So I was thinking instead of me just picking all the fields for the submissions forms I could get everyone else involved and we could come up with the new submission forms together.

Here's the list of submission forms we need:
Character
Stage
Item
Assist Trophy
Pokémon
Adventure Stages
Subspace Emissary
Bosses
Event Matches
Trophies

For trophies...

Name:
Series:
Origin:
Date Of Origin:
Works:
Trophy Description:

Can't forget 'Image:' lol

For Characters, what about adding in an optional space where we can place links to images that could be possible alternate costumes. And by alternate costumes I mean costumes, not recolorings.
