What is the joke in these four pages?
a) Deathstroke and Trigon are the parents of the two girls, so they are mortified to find that their fathers are going to be teaching in the school. Also, Trigon is a monster.
b) Deathstroke and Trigon are old-time enemies of the Teen Titans, have killed multiple members of the team over the course of 30 years of continuity, and are a nod to those times.
If your answer was B, you aren’t qualified to review Tiny Titans, one of the most adorable comics I’ve ever read and one you can give to just about any kid. It’s like the Muppet Babies– any continuity nods are secondary to the visual humor.
I mean, if you feel like Tiny Titans requires obscure continuity knowledge, you must shake your first in rage every time the Chiquita Banana lady shows up on Bugs Bunny, screaming out “Why don’t they explain who she isssssssss,” right?
