Jeice's History
Background
Jeice is from a planet located in the same planetary system as Salza's home planet, Coola No. 98.[5][6] Also, the video game Dragon Ball Z: Budokai Tenkaichi 2 states that Jeice and Salza are of the same race. Like the other members of the Ginyu Force, Jeice's special powers originated during his childhood: Jeice was a pitcher in the Galactic Little League, and it is there that he developed the Crusher Ball as his special technique.[2] Soon, while Salza became the leader of Cooler's Armored Squadron, Jeice was recruited in the Ginyu Force led by Captain Ginyu. Jeice has a rivalry with Salza, the two arguing about things like who is the better fighter and who is better looking.[7]
Frieza Saga
After landing on Namek and posing for Frieza, Jeice and the rest of the Ginyu Force find Vegeta, Krillin and Gohan trying to get Vegeta's wish of immortality. Before Ginyu takes the Dragon Balls to Frieza's Spaceship, Jeice, Recoome, Guldo, and Burter do Rock-Paper-Scissors to decide who gets to kill who.
Like Burter, he lost the initial Rock-Paper-Scissors contest with Recoome and did not get to fight either Gohan, Krillin or Vegeta. However, after Guldo's death, Jeice becomes frustrated, not due to Guldo's death, but that their posing positions will look completely stupid without Guldo. Jeice and Burter then play to see who will get to take on the two Earthlings and finish what Guldo tried to start. After Recoome defeats Vegeta, Jeice and Burter allow him to have fun with Gohan and Krillin as well when Recoome requests to kill them also.
After Goku arrives and defeats Recoome with a single blow to the stomach and revives Gohan, Krillin and Vegeta using Senzu Beans, Jeice is not impressed with his scouter's power reading of 5,000 for Goku. Burter convinces him further that Goku just got lucky since Recoome let his guard down. He and Burter jump in to kill Goku, but the Saiyan proves much more powerful than they had anticipated.
For all his previous boasting before engaging in combat with Goku, Jeice becomes actually quite cowardly when facing Goku. Jeice and Burter attack Goku furiously, but Goku proves to be far too strong, as he manages to deflect Jeice's Ultimate attack, the Crusher Ball, with no problems, when Jeice and Burter attempt to perform a team attack on the Saiyan after realizing attacking him head on does not work. While battling Goku, Jeice is still confused as to why Goku is still reading at 5,000 while still overwhelming them, not realizing Goku is bringing out his power in only the instant he attacks.
After Goku constantly dodges more of Jeice and Burter's attacks, he defeats Burter, knocking him unconscious, giving Jeice another chance to leave the planet. Jeice fearfully leaves his comrades behind for Vegeta to kill them, against Goku's wishes. Jeice flees back to Frieza's Spaceship in order to inform Captain Ginyu of the team's decimation. Captain Ginyu becomes aggravated at Jeice's actions, running away from the enemy, and he treats him rather harshly as a result.
He accompanies Ginyu in confronting Goku, after Ginyu reads Goku's power Jeice comments on how it seemed weird. Ginyu berates Jeice for relying too much on his scouter by stating that Goku is probably capable of suppressing his true power for when he needed it. Ginyu estimated Goku's power to be 60,000 as Jeice is in disbelief at the reading but Ginyu says he might actually have a worthy battle. When the battle between Captain Ginyu and Goku commences, Jeice remains on the sidelines as a spectator, apart from one instance when he interferes, stepping in and trying to help Ginyu by firing a beam at Goku, distracting him while Ginyu grabbed him. This results in Captain Ginyu releasing Goku from his grip, warning Jeice never to meddle again while he is in combat, or he will get into deep trouble. Jeice then watches Goku use Kaio-ken to power up and is shocked as his power level increases even going pass Ginyu's power level. He then understands how Goku was able to beat him and his comrades as he calls the Saiyan a monster and is shocked when Goku exits the form and says he can go even higher than that. When Ginyu calls out to Jeice, the latter catches his scouter and watches Ginyu injures himself and uses his Body Change to steal Goku's body.
For the rest of his time, Jeice tags along with Captain Ginyu (who is at this point in Goku's body). Jeice arrives along with Ginyu in front of Krillin and Gohan, who are surprised to see that Ginyu has switched bodies with Goku. After Jeice does some posing for a while with Ginyu, Goku arrives in Ginyu's body, still damaged. Ginyu (in Goku's body) asks Jeice to read his power level on the scouter, thinking it will be 180,000, but only goes to 23,000, because of Ginyu not being able to use all of Goku's power. As Goku, Gohan, and Krillin battle against Ginyu, Jeice ultimately runs into Vegeta, who engages him in battle. As they quickly trade blows in Frieza's ship, Jeice manages to ram Vegeta into a ventilation shaft, he thinks he has gained the upper hand. Vegeta continues to toy with him before revealing to him how his strength has increased substantially.
When reading Vegeta's power level, Jeice's scouter goes haywire and he breaks it out of frustration. Not willing to accept Vegeta's strength, Jeice continues to attack Vegeta, only to get pummeled. Vegeta then relentlessly attacks, propelling Jeice into midair and brutally destroying him with the Genocide Breaker directly aimed at his face. Jeice begs for his life before being executed. After Jeice is eliminated, Goku expresses his disapproval of Vegeta's harsh behavior, but Vegeta quickly retaliates by reminding Goku why his conscience and emotions are weaknesses, and says that he did it to protect himself and the others.
In another instance exclusive to the anime, he and the rest of the deceased Ginyu Force members travel to King Kai's Planet and square off against the Dragon Team who were still training there. Jeice teams up with Burter again, though both are blasted into Hell by Tien Shinhan, where they fall into the Bloody Pond. They were invited by King Kai to test the strength Tien, Chiaotzu, and Yamcha had acquired through their extensive training.
Majin Buu Saga
In a filler episode when Goku is in the Other World, Grand Kai informs him that Frieza and Cell have teamed up and that they'd all been trying to escape from Hell. When Goku and Pikkon arrive, the likes of Frieza, King Cold, The Ginyu Force (excluding Captain Ginyu) and Super Perfect Cell were threatening and interrogating ogres in order to obtain a mean of escape. Jeice and the other Ginyu Force members tried to attack Goku simultaneously, but he defeats them all with ease and they fall into the blood pond. Jeice was defeated with a punch to the stomach. When Pikkon spins around creating a tornado-esque attack, he creates a whirlpool and the Ginyu Force is lifted into the air and they all fall into a mountain of needles, impaling them. Shortly afterwards, they all end up in a prison cell with bandages covering their wounds.
Jeice also viewed the battle between Goku and Kid Buu amongst fellow villains.
Dragon Ball Super
When Goku and Krillin were sent into a forest to retrieve a special herb for Master Roshi, an illusion of Jeice and many other villains from the Z-Fighters' past show up to challenge the duo.
