What they got right: The writers continue to make use of the lesser-known DC characters, although the Patrol would be known to the younger readers if they've seen the Teen Titans cartoon. It's from the cartoon that the super villain of the issue gets his design, but then again I haven't seen him in the comics to say that for certain. Still, it's the voice I heard, and he's my favorite Titan villain from that series, so I liked seeing him.
What they got wrong: Even if this series does take place separately from the Teen Titans cartoon, and therein the Teen Titans Go! spin-off comic, Beast Boy hasn't been part of the Doom Patrol in any version for a long time now. So I have to wonder about his inclusion in the team. Also, maybe the "Secret Files" section should include the opening cameo characters, as I doubt anyone in the target audience knows who the Olympian is. I know I didn't until I looked it up online.
Recommendation: Still a comic worth reading.
