Matt Groening vs Seth MacFarlane (second verse is Homer Simpson vs Peter Griffin, then Matt Stone & Trey Parker come in and are follwed by Eric Cartman & Kenny McCormick) It's a battle of the three most relevant and revolutionary adult animated sitcoms.

Peter Parker vs Peter Pan

Flash Gordon vs Zapp Brannigan (with Kif Kroker)

Joseph Smith vs L. Ron Hubbard (featuring God and Xenu, and maybe finished off with Richard Dawkins coming in to show them up)

Charles Darwin vs Professor Oak (I know it's already been suggested a hundred times so I don't take credit for coming up with it but I think it's a necessary battle for them to do so I advocate for it strongly)

Morgan Freeman vs David Attenborough (battle of the best speaking voices)

Key & Peele vs Jake & Amir vs Cheech & Chong vs Jay & Silent Bob vs Rhett & Link vs Smosh

Steve Irwin vs anyone. Steve Irwin just has to be included in a rap battle someday.

Willy Wonka vs Ronald McDonald

Tony the Tiger vs Snap, Crackle, & Pop vs Cap'n Crunch vs Lucky the Leprechaun
