How does Kadaj summon using a support (blue) materia?

dont use the video games rules. just because its blue doesn't mean its support materia. thats just the colours used in a game. before you argue against this if you plan to, can you give me a good reason that it shouldn't be blue other than "it was red on the game".

Why doesn't Bahamut look like Bahamut?

its a different bahamut. think of it as the 4th bahamut. i think its official name is bahamut sin.

Whatever happened to fighting with materia? (I think someone should have at least a restore equipped...)

i guess its not neccasary and it would make the film seem nerdy if everyone was using materia. kadaj using it is enough i guess.
