As for titans, I’m regurgitating a memory from somewhere that there would be 20 or so titans and they’re all predefined? That might be a mismemory coming from there being something like 20 titans up for being created as a Kickstarter tier but I dunno. Intro music would be awesome for each, though it does stack up the amount to do. Perhaps there could simply be an into theme for all titans, though I think the dynamic duo could handle it.
