A2 is exactly like 2B with the exception of her down special, dodge animation, taunts, and side special. The manner in which she fights is more powerful, arrogant, and aggressive than 2B. With the exception of her neutral special, A2 does not have Pod Program attacks, but she is technical in her own special ways~
Down special: Berserk Mode
Tapping it gives A2 a mighty damage boost to her strikes, in exchange for 15% of her health and making it easier to launch her off of the stage. The self-inflicted damage slowly accumulates over time.
When you hold down the button instead of tapping it, however, A2 explodes and it injures nearby opponents upon activation.
The downside is that holding it takes a while to activate and leaves you susceptible. As a visual indicator, A2's body glows red the total duration that Berserk Mode is triggered. Functionally, the move is like activating Arsene on command, at the cost of your health. Berserk Mode has a 25 second cooldown period when it deactivates before you can initiate it once more.
Side special: Evade Boost
Unlike 2B's dash, A2's is slower and deals damage. When used while Berserk Mode is activated, A2 is less visible, only leaving behind a red blur. The dash is also faster if A2 is in Beserk Mode.
Taunts: In addition to using her down special, you can interrupt any of A2's attacks with a taunt to initiate Berserk Mode. All of A2's taunts work online because they are integral to her move list and where her true strength lies. Precisely, this betch not only has attack into taunt true combos, but it is her blueprint - her very stratagem. A2 is all about getting inside of your opponent's head. She is mind games personified. Is she going to keep dishing out combos or stop in the middle of one to taunt and level up in the process? You never know.
When she dodges, she turns invisible like Mewtwo.
