Title says it. Who you got in the biggest rap battle the DCU has ever seen?
My first instinct is Wally West. He has the disposition, and his perception of time means he’s got all the time in the world to come up with a devastating rhyme mid-verse.
My second thought — NOT Etrigan. Sure, he can rhyme, but his flow is wack.
By virtue of being a Rap God, he probably exists outside the multiverse and can travel to universes as he pleases. So the map of the multiverse looks like this-
Gotta co-sign on Wally West! In fact, I am of the belief that his style would be so next level that it would turn into a new way to fight crime. He could drop fresh, freestyle rhymes about making better choices & not being a thug & all SO FAST that it would (temporarily) disable the villains from being able to think about anything but the knowledge he’s laying down for as long as he keeps the flow going… or something kinda like that.
Also, with regard to team-ups, I suggest Wu Tang formation: “The Genius” - Mr. Terrific, “The Scientist” - Wally West, & “The Specialist” - Cyborg. That’s my start, anyway, because everybody knows, Wu Tang Clan ain’t nothin’ ta !@#$ with.
