I'm a fan of this game.

I really don't get why he's hated, he's a fun character to use, an important part of the plot, I can still take the character seriously, and he is used in many of my main teams.

Is it because he's not human? I doubt it, because Red XIII seams to be a liked character.

Is it because he only has two Limit Breaks? Stupid reasons, because Slots is like a load of Limit Breaks in one.

Is it because he's a "Weak" character? Again a strange reason, because like all FFVII characters anyone can be your best character if you level them up correctly.
