A five issue-mini seems fair though thank god they seem to be bringing back his streamlined second costume, I usually like retro campy looks but nothing about that original design worked from the 80s jumpsuit to the ponytail.
Mixed on Peter David returning to do it, I did like both of his runs but I always felt Genis himself was a secondary character in his own book with the real focus being on Rick Jones and Marlo who while I both grew fond of feel will once again dominate the story. According to Marvel wiki this also be Marlo return in over a decade and what bad luck for Rick to finally escape being merged with someone in Immortal Hulk only to find himself and Genis merged again.
Hope Phyla and Teddy will make appearance, were finally at point when all 3 of Mar-Vell kids are alive again lets have them finally all meet. Wonder if Genis will make note of Teddy forming a Kree-Skrull alliance it was after all a vision of that along with the Shi'ar that went on to dominate the universe that caused him crazy last time. This is a guy who killed his own infant son to protect the future I'm sure he'd willing to do the same to a newly met half-brother.
