I dont really watch power rangers(Sentai > Power rangers) but heres some suggestions.
alist of special moves(and some i made up) Pink ranger does in Zyuranger:
Rolling Arrows(suggestion) - Shes jumps into the air and shoots mutiple arrows. it also can be done on the ground.
Turn off attack - Im not sure..
Pteranodon(Suggestion) - She jumps into her plane thing and shoots everywhere, kind of like Jins Super or you can make it like Megamans beat plan.
Howling Cannon(Suggestion) - Her Bow transforms into the team attack weapon and shoots a large blast.

I don't think this would be hard to sprite.
WOO! WOO! WOO!
