Grey Matter is a tiny little alien dude who has popped up in every iteration of Ben 10 so far. And now, you can add the Dynamite comic book to the mix, as the little rascal will be introduced in September’s Ben 10 #5.
Written by Steven T. Seagle with art by Robert Carey, the issue will continue Ben’s fight against killer clown Zombozo, who first appears in Ben 10 #4. And thus far, Dynamite is touting that Ben 10 is an enormous hit, with issue #3 sales dropping from issue #2… By 56 issues. Which is a wildly small attrition for a title, three issues in.
Here’s the synopsis for the upcoming issue:
Ben has all the power of a number of new and strange alien forms at his disposal, but will any of them be enough to stop crazed clown Zombozo’s mission to spread his brainwashed circus across the entire nation? Ben has an ally with a strategy he doesn’t want to believe is true, but with Grandpa Max’s life on the line Ben has to decide: Is it hero time? Or something else entirely…? And don’t miss the comics debut of Grey Matter! This issue features a PREMIUM MYSTERY BLIND BAG which contains three limited editions of the issue selected randomly from a range of variant covers exclusive to this offering. Please Note: The number of Blind Bags is limited. Allocations may occur.
