They said "fusion is a cheap tactic to make weak things stronger!" but I disagree. Here's a fusion between Ricky (dragon) and Lloyd Mojave (ultimately decided the placeholder name for that red dragon would be permanent). An impossibility, but it would be kinda cool if they could fuse.

Fusions are also surprisingly difficult to draw, since I wanted to include elements from both of them, which went south quickly when I tried to decide on what color the scales and the hair would be.
