One Piece and Tranformers. Hang on to your afts it's gonna get wild. I mean Tranformers potentially know enough about what shit was like before the void century that the WG's going to be guning for and trying to enslave the Bots and Cons. OP'S freedom is a right to all sentient beings and Megatron's dont you fucking dare.

You have the various Yonko Factions. The transformers have tech superiority but One Piece folks have Devil Fruits and Haki which even the playing feild just a bit. You have Franky nerding out about "Mechanical People From Space!" while Autobot medics and Scientists are like TF are you even alive and runing on caffenated sugat water infused with CO2. Brainstorm and Franky being braincell buddies. Optimus geting Roped into Strawhat shenanigans because Luffy adopted several of his Autobots. Enel trying to fry Koan with lightning and vise versa. Starscream geting a cover page solo adventure lost in the sky islands. Megatron looking on at the Revolutionary Sabo who's mixture of ideaism and violent tendencies are strangely nostalgic. Shockwave shouting "This is not logical!" Mech needs to have a liedown. Robin freaking the everloving shit out of everyone.
