A-Trans

A-Trans (Aトランス) is an ability of Axl that appeared in the Mega Man X series. By defeating powerful enemies, Axl absorbs their DNA into himself, allowing him to access a new form and its powers, albeit at a somewhat limited scale. Axl uses a copy chip in order to use A-Trans, typically on a timer, and as the energy runs out, he reverts to normal.

In the Mega Man ZX series, Biometal Model A has a similar A-Trans (トランスン) ability in Mega Man ZX Advent. Like Axl, the Model A Mega Man is able to absorb the DNA of a powerful enemy to transform into a copy of the enemy, although not all abilities become available. Unlike Axl, Model A's transformations don't appear to have a time limit. Master Albert, the creator of Model A, claims he can use the "real A-Trans" (真のトランスオン) that can control all life when combined with Model W (or more specifically, its merged form Ouroboros), allowing to perfectly copy and control a target by using the souls absorbed by Model W.
