Well... here is...
1. Blaze Fantasy Creature
Flame, fire, blaze... its could be awesome! But... the blaze ones? Yeah, like Blaziken the HUGE thing from a... little chick! Well, impossible! Look at the Blaziken's evolution chart:
Baby First Ev. Fully Grown
Torchic -> Combusken -> Blaziken
Is an epic huh?
2. UltraSpeed Fantasy Creature
WHHOOOOOOOSSSH!!!! Maousy and Wilky... but if they have a SUPER SPEED? Like a Sonic using Bunny Hood at the brawl... :p
3. Aura Fantasy Creature
Yeah... a purple fire is called "Aura" A-U-R-A
PETZ FANTASY MUST HAVE!!!
4. Other attacks
I like the rainbow attack by Nyan the Poptart rainbow cat... puff attack... and more!
5. Evolution
They must have pre-evolution and evolution!!!!
