It is a bug (of the sort that arises when there is coding inefficiency), and it's pretty unfortunate given the short challenge duration. There are only two gold Doomsday characters otherwise, and Doomsday Containment is kinda weak for the later difficulties of the challenge, albeit, so would a lesser promoted Doomsday/Blackest Night.

It makes you wonder if Doomsday's character gear works on him, though.
