Elongated Man's powers and abilities
Meta-Human Physiology
After Ralph was struck by the dark matter energy after the Flash's release from the Speed Force, this altered his DNA and cells in a way that Earth-2's Harrison Wells found most intriguing (and considering the number of meta-humans and their roster of logic-defying abilities and powers that Harrison encountered thus far, that's saying something), polymerizing the walls of his cellular structure, causing them to be elasticized to form an unbreakable bond at an atomic level, enabling him to access his new-found powers.
Elasticity
Ralph can stretch, contort, and compact various parts or his entire body into a myriad of different shapes and sizes. After taking a chemical stabilizer given by Caitlin Snow, he was able to retain a degree of "muscle memory" and revert to his leaner, fit state (or "default form").
Superhuman Durability
As a side effect of his elasticity, Ralph is also rendered highly durable, mitigating any impact he may receive with little consequence as his body expands and contracts, in and out of his normal human shape, to render said impacts obsolete and even cause projectiles to bounce off from his person, after absorbing the said projectile into or through his body, and immediately rebounding it back to the direction of the source. He took no harm from a bullet to the head, and a punch to the face only inconvenienced him as his body would stretch and cushion the impact to ultimately negate it; though it was implied that certain other forms of assault could still harm him, since a Viber meta-human from Earth-19, "Breacher", claimed that he could kill Ralph after furiously firing a vibrational blast at him and then followed it with another. It would appear that his insusceptibility to outward and solid physical harm is not limited to blunt assaults, since Ralph took a gargantuan bite to his outstretched torso from the teeth-filled jaws of a mobilized T-Rex skeleton without sustaining much harm to himself, despite something like that would have surely bifurcated a normal person in half. Ralph managed to withstand enough explosives to destroy a city block, though he did comment that it gave him heart burns right after doing so. Later, Ralph exhibited a marginally reasonable resilience against Axel Walker�??s Axid, sustaining only moderately superficial damage on his knee that did not impair Ralph in any way.
Shapeshifting
Ralph gained the ability to physically change the bodily form of anyone he can clearly picture within his mind. This was discovered when Ralph was describing his old business partner, Earl Cox, to Team Flash, and while doing so, he gradually started changing form from body part he described to body part, including his voice and accent, until he was in the full form of Earl. Ralph further on used this ability to masquerade as Gregory Wolfe and Clifford DeVoe, the latter of which he used to successfully testify for Barry Allen's freedom. However, as he was still unused to this new facet of his elastic capabilities, maintaining himself in the likeness of another's form taxes Ralph to the point where, apart from not being able to retain the said alternative likeness for as long as he would have liked, showing signs of gradual reversion until snapping back into his true form eventually, the assumed form also somewhat hampers Ralph's natural mobility - causing him to experience some difficulty in both movement and locomotion.
Superhuman Strength
Ralph has also demonstrated considerable strength, possibly attributed to the now substantial bonding of his cells at the molecular level which also refines his physical parameters and muscle definition. He was able to grab onto and stop a helicopter mid-flight with his extended arm and allow the Flash to run up his extended arm with ease, although he was somewhat strained by the act, and later (quite literally) single-handedly prevented a speeding car from driving away, with only one outstretched arm gripping the car from behind, while anchoring himself to another vehicle with the other arm. Ralph later showed being able to knock down a mobilized t-rex skeleton with a single hit from an enlarged fist.
Abilities
High-Level Intellect/Expert Detective
As an ex-police detective of the Central City Police Department, Ralph runs his own private investigation business and is very experienced in detective work, and has shown being able to tell an encountered woman's vital statistics with a simple glance (much to the discomfort of females) and claiming to have never had a case he could not solve. At one point he was Barry's senior for this field and was seen successful in closing several cases whilst working as a PI. He was able to discover a woman's husband, who was still alive after being assumed dead and had even even remarried, relocated and conceived two children. He is also very good a reading people's honesty as he saw through Carla Tannhauser was lying about Thomas Snow's death. Despite being oblivious to the existence of the multiverse and failing to notice Harry Wells was from Earth-2, he was able to deduce that time travel was possible and that the multiverse existed.
Skilled actor
Ralph was successfully able to impersonate Clifford DeVoe to get Barry out of jail for his framed murder, and he has tricked Earl Cox by impersonating Joe West.
Police Training
Ralph has received training, as all Central City Police Department members do.
Keen Sense of Smell
Ralph has a very keen sense of smell capable of detecting and distinguishing scents even behind a concrete wall.
Expert Combatant
Ralph has shown to be an expert in unarmed combat as he was able to defeat multiple of goldfaces thugs.
Skilled Marksman
Ralph is shown to be adept with guns. He and Barry once used guns stolen from Goldface to fight and knock out all of the latter's forces, as well as briefly stun Goldface himself.
