Don't worry its not really a problem. To me it actually sounds like a good thing, as far as creativity goes.
My view on RHG is that its cool and all, but it doesn't have to be the only character you create. For example ENDO, his official RHG is Chuck, but everyone knows of Beard Ninja just as well. Terkoiz's RHG is FLLFFL, but everyone knows Mr.Red , Trucido (I hope I spelled that right), and the Gra fight guys (so yeah, he's done a whole lot of different characters).
Just make your RHG the one that you like animating the most and can be most creative with. Its not like you have to stick to animating only one thing, but as far as battles, that's just how RHG works.
TL;DR
Pick your favorite & do your best
