Because the months of the year were a little disappointing. This feels a little more like they’re trying.
I think my favorite is Maandag, but that’s just because I remember his adventures trying to tear up the ersatz X-Men team Psi-Force in Marvel’s short-lived and completely unloved New Universe line of comics. His most vicious attack was to remind the team they were in the New Universe and would probably never get promoted to the real comic book industry. But really, Maandag! Half-maan, half-dag! He’s unstoppable, unless someone tries. Aren’t we all?
