Darwin has the power of "reactive evolution"; I.e., his body automatically adapts to any situation or environment he is placed in, allowing him to survive possibly anything; the exact nature and limits of his powers have not been revealed.

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; morphing into a sponge when shot at with a weapon designed to destroy the subject's nervous system; 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.

His power can also work when dealing with non-immediately-life-threatening situations, such as rendering it impossible for Darwin to get drunk by allowing his body to process alcohol faster than humans would normally.
