Heee good ol' Boomerbutt. He fit right in on the Squad because he had the same "you're disposable" attitude that the higher-ups did. He really was good for the book and the book was good for him. That was from the days when DC could make good editorial decisions.
As a Battle of the Planets fangirl, I absolutely howled with laughter the first time I saw the Captain's sonic boomerang. Alright, now who else is picturing our Captain in the birdsuit? Anybody? Anybody? Aw come on, I can't be the only one left, can I? No motto at all? (Maybe one day I will write a fic about the Captain and the Pied Piper getting their heads together to create that sonic boomerang. I'm sure there's a Boring Story in that...)
