Corner
[508] Kazuya [s.HP xx EWGF, EWGF, c.HP xx EWGF, c.HP xx EWGF, EWGF]
Counter hit:
[530] Kazuya [c.HP (ch) xx EWGF, EWGF, c.HP xx EWGF, s.HP xx EWGF]
2 Bars:
[597] Kazuya [s.HP xx EWGF, s.HP xx EWGF, EWGF, Super]
Max Damage:
[620] Kazuya (corner) [j.HK, s.HP xx EWGF, c.HP xx EX Slaughter Hook, c.HP xx Super]
Note: The last combo really isn’t worth it. He can get 619 off j.HK into the above 2 bar combo and 680-729 off a j.HK into Cross Art combo (the 729 belonging to Cross Art with Hugo). But in terms of solo max damage, that was the best I could find.
