Charmcaster's History
Ben 10
In Charmcaster's debut appearance, Tough Luck, she busts Hex out of prison and assists him in trying to steal the Lost Keystone of Bezel which can re-create the other five charms to greatly strengthen and increase Hex's abilities. She manages to trick Gwen by putting on an act about Hex forcing her to help him, only to swipe the Keystone while hugging Gwen. She then gives Hex the Keystone. In the end it is revealed that Hex needs the Keystone to recreate the five Charms of Bezel, and that she is planning to take their power for herself, but fails, as does Hex.
Charmcaster returns in A Change of Face. She attempts a body swap spell with Stinkfly in Salem, Massachusetts. She was hoping to take control of the Omnitrix and combine its powers with her magic in order to become invincible. Her efforts fail; however, as her attempts only end in swapping with Gwen, on her second try she was returned to her normal body while Ben and Gwen are swapped, and the third time resulted in returning Ben and Gwen to their normal bodies. She is arrested at the end of the episode, and her bag is tossed into the harbor. She is last seen in juvie, where she is about to be beaten up by Pinky and Missy, whom Gwen angered during her stay in Charmcaster's body. Gwen obtains her spellbook, and keeps it as a souvenir, eventually learning to use it.
Charmcaster makes a cameo appearance at the end of Don't Drink the Water, where she is seen taunting Hex (who has been reduced in age to an infant by the waters of the Fountain of Youth) and saying that she'll be giving the orders now. Charmcaster's final appearance in the original series is in Ben 10 vs. the Negative 10 as part of the Negative 10. Unlike her partners, however, Charmcaster is only focused on defeating Gwen (as opposed to Ben like everyone else was). She also is shown to have a small rivalry with fellow Negative 10 member Rojo.
Alien Force
Charmcaster returns in In Charm's Way, where she sends one of her stone creatures to attack Ben, Gwen, and Kevin while the trio were spending the day at the beach. The rock creature appeared to be immune to Gwen's energy attacks and proceeded to oust Kevin. Just as Ben was about to take down the rock monster, a magical portal opens up and sucks it away. It was later shown that Charmcaster was hiding in a nearby cave watching it. After voicing her deep hatred for Gwen and her plan to take something precious from her, since Gwen stole her spellbook, Charmcaster used a spell that transformed her into a beautiful, blonde-haired teenage girl named 'Caroline' as part of her plan to charm and hypnotize Kevin.
Charmcaster set her plan into motion after saving a child from being killed by a truck. Afterwards, she and Kevin journey to the beach where she revealed a partially false life story while removing the ID mask that concealed Kevin's mutant form, clearly growing jealous of Gwen when Kevin mentions "You think you can do magic? She's made of magic". She then kisses him, hypnotizing him and putting him under her hypnotic influence through a spell, and then ordered him to bring Gwen to the Planetarium before midnight where she can drain Gwen's magical and Anodite powers. To fortify or endeep her hypnotic control over Kevin, she also granted him a magic amulet. After a skirmish with Ben and Gwen, Kevin was broken free from Charmcaster's influence spell after the amulet was broken by Ben. After the trio arrives at the Planetarium at Gwen's request, Charmcaster sends her rock monsters to deal with Ben and Kevin while she dealt with Gwen herself. Upon meeting, Charmcaster gloats sarcastically at Gwen's hairdo then engaging her in a short magical duel, in which Gwen was led to stand in the middle of a circle of runes that were placed directly under the sky-panel. After luring Gwen into the trap, Charmcaster opens the runes, exposing Gwen to the full blaze of the moon light and forcing her onto her knees in agony. This helps Charmcaster in fully subduing Gwen. She then drains Gwen of all her magic and transfers it to herself. Confident that she had won, Charmcaster retreats with her two surviving rock minions while Ben and Kevin go to Gwens' aid instead of pursuing her.
After a short argument with Gwen, Kevin tricks Charmcaster into meeting him on top of a tall building where he lured her with a lie about his loyalty to Ben and that Gwen still had power left, angering Charmcaster even further. The duo later shows up at Mr. Smoothy, where Ben and Gwen are having the restaurant's namesake. After scanning Gwen, Charmcaster realized that Gwen had no power left and that Kevin managed to trick her. She uses a spell to bring a Mr. Smoothy sign to life as well as controlling a parked van to kill Kevin and Ben, while her rock monsters attempted to annihilate Gwen, who mocks Charmcaster and proceeds to challenge her to a one-on-one fist fight, which Charmcaster nonchalantly turned down, opting to kill Gwen with a bolt of mana. However, Gwen turns the tables on Charmcaster by reciting one of her spells and reabsorbs her stolen Anodite powers from Charmcaster, much to Charmcaster's horror. Powerless, Charmcaster gets help from her rock monsters to make one last stand against Gwen. Charmcaster was finally defeated after Gwen summoned a mystical vortex which sucked her and her rock monsters away.
Charmcaster appeared in Time Heals with her uncle Hex. In this episode, her uncle was awakened by a disturbance in their home late at night, only for Charmcaster to convince her uncle to return to bed. The disturbance was actually Gwen, who snuck in to steal one of their books that had a spell that'd allow for her to travel back in time in order to stop Kevin's mutation. When this happened, an alternate timeline was created: one where Hex and Charmcaster ended up ruling the Earth. Because the accident that mutated Kevin never happened, the Kevin of this timeline was weaker, and Ben's Team was unable to defeat Charmcaster and her uncle. Charmcaster managed to murder the Gwen of this timeline and absorb all of her powers, also forcing Kevin to absorb the material of her rock monsters, giving Charmcaster full control over Kevin. Without his team, Ben was easily defeated by Hex and imprisoned in the dungeons as Spidermonkey. When Gwen freed Ben, Ben fights off Charmcaster, Hex, Kevin and the rock monsters as long as he can so Gwen can repair the damage she had done in the past, presumably dying as a result of this.
Ultimate Alien
Charmcaster returns in Hit 'Em Where They Live, where she assists Zombozo and Vulkanus in a plot to kidnap Ben's mother. She was defeated by Kevin, who scares her away by almost causing a roller coaster to crash on her (If the episode is played scene by scene, it is shown that Charmcaster escaped before getting hit); Kevin was making sure she was not killed as he had promised Ben and Gwen not to finish off his opponent.
In Where the Magic Happens, Charmcaster is brought back to her home, Yahwahtacsip (Ledgerdomain as the natives refer to it) to bring help to Gwen and the team. In this episode much is revealed about Charmcaster's past and her feelings toward Gwen. It was shown that Charmcaster had always dreamed of becoming a great sorceress, saying that she had studied magic her whole life but found it extremely unbelievable that Gwen could just come out of nowhere, steal her spellbook and become so strong and powerful and suddenly 'out-magic' her. It is also revealed that when she was a child, her father Spellbinder and her people were at war with Addwaitya, the greatest magical, mystic being that has ever lived. Her father helped her and Hex escape safely to Earth, but failed in battle and was murdered by Addwaitya. Charmcaster's villainous actions were all to gain more and more power so that she could return to Ledger Domain and defeat Addwaitya. Charmcaster moves past her feelings of resentment toward Gwen and actually develops a friendship with her, chiefly due to learning that the two of them are actually stronger and more powerful as a team than individually; her knowledge of magic coupled with Gwen's Anodite powers. She even ends up putting her life on the line, buying time for the trio to escape, leaving herself behind in Ledger Domain with the hopes of defeating Addwaitya at last.
In Enemy of My Frenemy, Charmcaster has become corrupted with power during her time fighting for Ledgerdomain and relapsed back into her evil ways when the denizens she'd fought to free from Addwaitya turned on her and fought a massive civil war to decide who would become the new ruler; a war which Charmcaster won. Building a device that drains the souls out of living things, she enacted a plan to drain the life force of her world in order to perform a ritual that will bring her father Spellbinder back to life. Ben, Gwen, and Kevin attempted to stop her, but their souls were sucked out as well. When Spellbinder was resurrected, he reveals that Charmcaster's real name is Hope. Horrified at the lengths his daughter has gone to in order to bring him back, he says he can't stay at the cost of so many souls. Telling his daughter that he loves her, he fades away, making the ritual null and void and returning all souls back to where they belong. Charmcaster breaks down crying, not knowing what to do with her life now. Out of pity, Ben, Gwen, and Kevin agree not to arrest the heartbroken Charmcaster and depart from Ledgerdomain.
In Couples Retreat, Hope falls in love with Darkstar when he attempts to get into Ledgerdomain. She supplies him with a lot of mana when they kiss multiple times, and allows him to go back to Earth to take revenge upon "his enemies", not knowing this to be Ben, Gwen and Kevin. She also reveals her true name, Hope, to him. When Ben, Gwen, and Kevin arrive at her castle, she fights Gwen while Ben and Kevin take on Darkstar, and becomes enraged when she learns Darkstar and Gwen once dated. Gwen, concerned about Hope, tries to convince her that Darkstar is merely using her, but Hope seems hopelessly deluded. However, just as Darkstar offers her the chance to team up with him and conquer Earth, she realizes that Gwen may be right and asks Darkstar why he never calls her by her real name, and if he even remembers it. After Darkstar doesn't, Hope becomes so enraged that her screams destroyed her castle, then drains Darkstar's powers and banishes him from Ledgerdomain, leaving him at the mercy of Ben, Gwen, and Kevin waiting to beat him up. Charmcaster is last seen at the ruins of her castle, sadly looking down upon Darkstar's mask.
Omniverse
By the time of the Omniverse series, she is gradually becoming corrupted again, this time partially due to an outside influence. Charmcaster makes her appearance where she appears driving the police car carrying Darkstar disguised as a police officer. When asked if she had forgiven him, she responds by turning him into a totem.
In Charmed, I'm Sure, Charmcaster appears on Anur Transyl to take back the Alpha Rune, which had been stolen by Zs'Skayr. She teams up with Ben, Rook Blonko, and Hobble (who has a crush on her) to get it back. When they reach Zs'Skayr, he gives the Rune back willingly since he has already drained it of much of its power.
Charmcaster puts the Rune on and goes mad with its power, summoning rock creatures that she turns into battle armor for herself. She suddenly turns on Ben and attacks him, but she is defeated when Hobble throws the magical artifacts in Rook's arsenal at her, which destroys her armor. Rook then uses a teleportation spell from Gwen's spellbook to teleport her back to Ledgerdomain.
In Ledgerdomain, it is revealed that Charmcaster betrayed Ben under the advice of Addwaitya, who has been turned into a stone miniature that is kept in her bag along with Darkstar, both of whom she has been speaking with all episode (leading others to believe her to be crazy since only she could hear them). Addwaitya assures her that she will be successful next time, to which Charmcaster threatens him to remember that she controls him now, not the other way around. When she asks why she shouldn't just smash both of them, Darkstar whispers a plan into her ear that she evidently likes.
In Charm School, Charmcaster attended Friedkin University at Hex's word hoping that the two of them can be closer. However, Charmcaster only came to Friedkin University to obtain a powerful artifact known as the Staff of Ages. Charmcaster's first attempt that getting the Staff of Ages was a failure due to Hex being powerful in his library. However, Charmcaster managed to turn Hex into a totem after impersonating Professor Xagliv. Charmcaster obtained the Staff of Ages from a book in Hex's library but it was soon taken away by Gwen. Charmcaster managed to take back the Staff of Ages and completely overwhelm Gwen due to Charmcaster possessing Hex while in his library. Charmcaster continued to fight Gwen until Ben as Ghostfreak joined in the fight along with Kevin, Rook, and Zed. Charmcaster summoned some Stone Bats and had them go after Kevin, Rook, and Zed while Charmcaster went after Gwen and Ghostfreak. Charmcaster easily defeats Ghostfreak and sends him flying into the library. However, Charmcaster was then outmatched by Gwen who took back the Hex totem and was more powerful in the library. Charmcaster lost the Staff of Ages and was sent back to Ledgerdomain.
In Third Time's a Charm, Charmcaster lures Gwen to Ledgerdomain and turns her into a totem. When she returns to the library at Friedkin University, she learns of Bezel's presence there and tries to take his power. She succeeds when she turns him into a totem, and then attempts to destroy Ben, Rook and Kevin, even transforming into a dragon. But Ben and Gwen trick her into getting turned into a totem and sealed into her own bag, which she declares a temporary setback and vows revenge. Gwen keeps Charmcaster, still inside the bag, in her headquarters and is hopeful that under these circumstances the two of them can finally be friends.
Charmcaster appears, no longer a totem, as one of the many female contestants vying to marry Ben in The Most Dangerous Game Show. She loses in the third round when she flies across a lava pit only to crashland on a floating rock when a lava bubble bursts dangerously close to her. She is then transported to the Null Void along with the other losers, until Ben arrives to set them free. Charmcaster, along with the other girls, helps to save Ben from the Way Bads before returning to Earth to help him face Charles Zenith.
It is unknown what happened to her after this. She either got zapped back into her bag magically or she escaped and is currently on the loose.
