Either Axel the Water Buffalo or Bearenger the Grizzly will be the Kommissar of the Efrikan D.E.L. chapter.The staff said that each branch of the Dark Egg Legion will have a Kommissar as well as a Grandmaster. In addition, they're not ruling out any post-Super Genesis Wave characters from appearing, especially since the comic is now in IDW's hands. And since Axel was the Egg Boss of the Efrikan Egg Army, and Bearenger is a bear (making him feel home in Diesel's chapter), I think either is a good choice to be Diesel's second-in-command.
Hershey is not dead, but legionized.
