This might take the cake for the most random yet mainstream appearance of a New Warrior.
Back in January, the long-running Funky Winkerbean comic strip by Tom Batiuk reminisced about Speedball, even spotlighting the cover of Speedball the Masked Marvel #2 by Steve Ditko! Crazy!
Oh the sub-text hilarity unknown to the general audience! Back in January Speedball was still the “deeply disturbed and borderline psychotic” Penance. Of course just this month, the bright fun-loving Speedball has finally bounced back in the pages of Avengers Academy, so maybe all hope isn’t lost yet.
(Thanks to Nebula of the New Warriors Source Forum. I can’t believe I missed this until now!)
