Superbot. You should add unblockable attacks and/or guard break meter. Preferrably guard break meter that refills at a somewhat slow, but still decent pace.
You can grab, but when it's at the start of a match and the person has no AP, grabbing is pretty useless at that point because you might get a whole 1AP from it. When they're at level two going for three though, grabbing is extremely useful.
Also, grabbing should atleast add some sort of AP bonus, not only drain AP from the enemy player.
