Writes Lee, here credited as "Co-Publisher, DC Entertainment":
We were so excited when the monsters team called us to help design their packaging because we've been fans since we were kids. We hope you love all of these designs as much as we do.Lee, Dave Johnson and Terry and Rachel Dodson took on the task of redesigning one of the General Mills monster cereals' Trinity (That is, no Fruit Brute or Yummy Mummy), and none of them went too far in terms of their redesigns; that is, none of the monsters look as radically different as the recent-ish redesigns of, say, Superman or Batman or The Creeper or pretty much any DC Comics character (For what they did do, check out Chris Sims' article at Comics Alliance).
Honestly, as soon as I learned that Lee and DC were redesigning the monster cereal monsters, I just sort of assumed the results would end up looking a little more like this...
...but you know what they say about making assumptions.
