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.

Other appearances
A-Trans appeared as a rare Action card in TEPPEN. When used, it copies the cards in the player's EX Pocket and returns them to the top of the deck in random order.

A-Trans is also one of Axl's abilities in his appearances as an event character in Dragon Poker and Elemental Story. In Dragon Poker it is a support skill that, under specific conditions, may grant a skill buff to the user (if the team leader has the same skill type as Axl), recover 5% HP to the party (if one member has an abnormal condition), or remove abnormal conditions from the party (if all members have the same condition). In Elemental Story it converts two Light pieces into Wood pieces (Axl's element) in the end of the turn.
