Handicapping like the 6th worst character in the game is pretty close to as unplayable in semi-high competition you can get.
The primary problem with it is you HAVE to parry, or find a -retarded move on block, guess or land a HP Flash Chop to land it.
That’s so incredibly unreliable, and you lose better EX Moves, which do actually garuntee damage and cover his weaknesses.
It’s just a bad super. If the opponent isn’t in the air during Gigas, Gigas just kills them, the only requirement is that they are on the ground, it cant combo, but it’s garunteed once the superflash goes off, Hyper Bomb requires them to be in some sort of inability to jump.
