Yes xD Metal is actually one half of a deity duo. Hes the archetype of destruction and violence, while his counterpart Jim Jr (not a DoppelRip) is the archetype of creation and peace. (This is an allegory of Metal music as a whole.)
The universe they inhabited is completely annihilated, and Metal's guitar is a weapon called The Hatchet of War. It was used to penetrate the shield around Black Heart's dimension so the characters in the RP could enter.
Bird Rip? Every day is a struggle for life and death against Nature. Survival of the fittest and all that xD
I just tend to create everything as a supplement to what I already have. Though if there was one escapism I do with my characters it would be drawing them playing Metal music and doing extreme sports, but...even that is a battle against establishment and societal norms.
Edit: I realize now that I take myself waaaaay too seriously xD I swear in RP settings I do have fun though
