Mega Man Model A using A-Trans to attack Chronoforce as Buckfire in Mega Man ZX Advent

A-Trans (Aトランス)[1] 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 Trans-On in Japan) 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 Shin no Toransu On, lit. "true Trans On") 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.[2]

Mega Man ZX series

Mega Man ZX Advent

Boss Image Description
Buckfire the Gaxelleroid
In this A-Trans form, access to a series of agility attacks is unlocked, including a diving kick that can destroy certain boxes. This is the fastest for travel in the game as the player is always in a dashing motion while moving.
Chronoforce the Xiphosuroid
In this A-Trans form, the player can move freely through water (similar to Model L), and fire icicles. His hide is completely invulnerable to all forms of offense. In addition, he possesses an electronic-disrupting technique called 'Time Bomb' that gives the sensation of slowing down time. Chronoforce is rendered immobile if not in water, but can still use Time Bomb combined with his hide makes his ability just as ideal on the ground.
Rospark the Floroid
In this A-Trans form, the player can climb ropes, shoot Rose Stingers, and use his whips to attack enemies on ground or attached to poles or electrify them with a charged attack as well as airborne enemies. On the ground, Rospark remains in an extremely slow-moving bulb form, while his true power blossoms in flower form whenever attached to a pole.
Argoyle & Ugoyle the Shisaroids
In this A-Trans form, the player controls Argoyle and attacks with AR Bombs, spherical weapons that explode after ricocheting. This form can 'infinite dash' and summon Ugoyle as a 'ghost' player that follows all over the player's movements and is invulnerable to harm. In addition, Ugoyle is not affected by terrain and can retrieve items in out-of-reach areas. There is a special monthly unlockable chip which changes the form's AR Bombs into soccer balls.
Queenbee the Hymenopteroid
In this A-Trans form, the user can fly into the air to collect items previously inaccessible. The player is also able to carry objects larger than itself, usually by pulling it from underground.
Hedgeshock the Erinaceroid
In this A-Trans form, the character can roll through small spaces without having to transform into their human form (very much like Sonic's spin abilities) and can cut through obstacles while doing so. She also has access to a Rakuhouha-like attack.
Vulturon the Condoroid
In this A-Trans form, the ability to stick to walls and weights to move them is available. The user is able to hover in the air until Biometal energy runs out.
Bifrost the Crocoroid
In this A-Trans form, the user gains a drastic size increase. Bifrost can attack with buzz-saws that deals multiple hits. Its other attack includes Ice Fangs that fire ice shards while the mouth is completed extended, giving the user limited invulnerability with the mouth. It also has two attacks not listed in the move list screen: Tail Swing, which flings enemies away while turning the opposite direction; and crushing enemies while falling to the ground or landing on them. The form's jaws are strong enough to destroy the plasma-powered electric blocks.
Aeolus - Model H
As a copy of Aeolus using the Model H Biometal, this A-Trans form allows the use of the same abilities of Model HX in the first Mega Man ZX game, including Enemy Analyzing.
Atlas - Model F
As a copy of Atlas using the Model F Biometal, this A-Trans form allows the use of the same abilities of Model FX in the first Mega Man ZX game, including Buster Edit.
Thetis - Model L
As a copy of Thetis using the Model L Biometal, this A-Trans form allows the use of the same abilities of Model LX in the first Mega Man ZX game, including Item Searching.
Siarnaq - Model P
As a copy of Siarnaq using the Model P Biometal, this A-Trans form allows the use of the same abilities of Model PX in the first Mega Man ZX game, including Night Scope and attacking enemies on the touch screen.
Vent/Aile - Model ZX
Imitating Vent/Aile in the Model ZX form is available. The abilities of Model ZX from the previous Mega Man ZX game are available for use, as well as a character-specific ability for Grey and Ashe that was not featured in the first ZX game. Grey's (Aile's) character-specific ability in Aile's form is 'Energy Fissure' ('Fission' in the English version), a downward stab move that spews forth rocks on impact, while Ashe's (Vent's) form is 'Rising Fang', which consists of a jumping upper slash and a saber-wave projectile (distinct from a Sonic Boom in that it does not penetrate enemies or obstacles). However, only the boss can link up this attack with the standard three-hit combo.

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.

  2. "I told you that you were made in my image. But my real power is not in my copy ability. The spirit of everything Model W eats lives on inside me. The power to control all life. That is the power of the ultimate Mega Man. The real A-Trans! They're waiting for you inside with their new bodies. Please go in and play with them. If you can make your way to me, I'll tell you everything, on how, even being incomplete, you can still use A-Trans, and who you really are." - Master Albert, Mega Man ZX Advent
