Frankenspriting

Frankenspriting is a way to make new and interesting sprites. The method of this is to gat a base sprite, several other sprites and merge them together sort-of. For Example: With Megaman, replace both his arms with Busters from other sprites, then recolour him.

One famous MUGEN creator that is known to use this method is TheRealSpiderMew. Infact he even has a Tutorial on how to Frankensprite on YouTube.
