Asschaco's alpha fires a big, slow moving projectile. It's heavy damage, but has a long startup time. However, you can also hold it down to rush forward and do a direct hit for even heavier damage (similar to All Might's beta, but even easier to land) at the cost of 3 ammo. The direct hit also launches the enemy quite far away.
At level 1 it has 5 ammo, the projectile deals 117 damage, and the direct hit deals 145 damage.
At level 4 its ammo increases to 6.
At level 9 the projectile deals 157 damage, and the direct hit deals 185 damage.
At all levels it takes 2.5 seconds to recharge 1 ammo, and recharges from empty in about 5 seconds.
Asschaco's beta is similar to Hawks's beta, but it catches enemies and deals repeated damage similar to Strike Bakugo's gamma. Its movement is input-based rather than camera-based, so it's a little harder to control than Hawks's beta. Pressing forward makes you ascend, and pressing backward makes you descend.
It is percentage-based, but no matter how little you use, it always starts recharging from 0.
At level 1 you get a maximum of 2 seconds of flight time, and it can deal a maximum of 120 damage to an enemy before it knocks them down. At level 9 you get a maximum of about 4 seconds of flight time, and it can deal a maximum of 150 damage to an enemy before it knocks them down.
At all levels it takes 4 seconds to recharge.
Her gamma is basically the normal Ochako gamma, but a bunch of smaller circles in a line in front of her like a Strike Shiggy alpha, rather than one big circle. Like Shiggy's alpha, the circles will go up/down elevation changes, though they won't spawn on walls.
If you hold down her gamma, it consumes all charges and spawns a single larger circle centered on you, which creates a floating platform. At level 1, the platform rises almost as high as the archway on the USJ bridge. At level 9, the platform rises a bit higher, reaching even with the points at the top of said archway. Mostly leveling it up just makes the platform larger.
As long as you are standing on something, there doesn't seem to be any limitation on spawning the platform except the fact that you can't be standing on an existing gamma platform. Even if you're standing on top of a Cementoss alpha or even in a tree, it spawns the full-width platform from that point. If you try to spawn it while standing on an existing platform, the new one just breaks instantly and the ammo is wasted.
Interestingly, there doesn't seem to be any limit on how many platforms can exist at once. If you turn on increased reload speed in Training Mode, you can get a chain of 8 into the air at once before the first one falls.
One interesting property of the large platform is that when it falls out of the air, the whole thing is apparently instantly turned into a projectile. This means that while enemies are able to stand on it, if an enemy is standing on it at the moment it begins falling, they will instantly take the same damage they would if they had been underneath it.
At level 1, her short-press gamma does 42 damage on ascent and 62 damage on descent. Her long-press gamma does 110 damage on ascent, and 80 damage on descent.
At level 9, her short-press gamma does 60 damage on ascent and 78 damage on descent. Her long-press gamma does 150 damage on ascent, and 120 damage on descent.
According to the skill details, reload speed is supposed to increase at level 4. But in my testing, at all levels it takes 6 seconds to recharge one ammo, and 12 seconds to recharge from empty.
Overall, she seems quite strong. Good mobility with her beta and the capacity to just fly through team fights, shredding people like a combination of Assault Kiri's alpha and Hawks's beta. 185 damage on a melee alpha that, while shorter-ranged than All Might's beta, seems easier to land. Crowd control and combo potential with her gamma, plus a bit of utility.
Of all the parts of her kit, her alpha seems the most likely to be a balance issue.
