Geez, are my questions too hard or something? Hardly anyone ever answers them (maybe they just don't like me...?).

Anyway, the answer is because Ansem created them. Reading the Ansem Reports thouroughly will prove it.

What's Squall's limit break called? (excluding the extas, like "Rough Divide")

There, if that's too hard, then ya'll need to pay more attention .
