Go into the costumes of the "OC" sprite, and replace the outline of a person with your OC. Also add your name and a brief description of your OC.
Sorry, I'm awful with text and it's a tad long so I'll write the backstory here. Spark was gifted - or you could say cursed - with the ability to transform into a being of immense power when he was angry. Now, before you say "ooh hes a hulk mary sue," let me explain. When he is in his powerful state, he loses control of his body, and acts only with malice and revenge. He attempted to fix this with an experimental cybernetic procedure, but failed and made his angry side stronger. (also, the brighter the red on his angry side, the madder and more powerful he is.)
