Armando Munoz, code-named Darwin, is a mutant with the power of "reactive evolution", the ability to develop a resistance or immunity to whatever they were injured by or exposed to, or instantenous adaptation to any situation. Actor Edi Gathegi has been cast as Darwin in the upcoming film X-Men: First Class.
Powers and Abilities
Darwin has the power of "reactive evolution". The exact nature and limits of his powers have not been revealed, but what this means is that his body automatically adapts to any situation or environment he is placed in, allowing him to survive possibly anything. Examples of his powers include: gaining night-vision after a few seconds in the dark; functional gills after being submerged in water; fire-proof skin after being exposed to flame; increasing his own intelligence; converting his body into pure energy; no longer requiring oxygen after being sucked into space; and acquiring comprehension of the Shi'ar language merely by looking at written samples. His power may concern itself with more efficient methods of survival than Darwin himself might choose; for example, instead of continually increasing Darwin's powers when taking punishment from the Hulk, his body simply teleported him away from the fight.
