[ Robbie teases people with nicknames like Buckethead and Supertights, once a solid rapport is established, but that's a different situation. He wouldn't feel comfortable with someone's codename being Idiot or Jerkface, and, once he thought about it, Brainiac didn't sit well either.

Brainy could be okay, but Robbie was hung up on Querl not knowing who the Smurfs were. The fact that it's obviously a pet name for Brainiac is now a negative. ]

Okay. So it's Querl on Legionworld and whenever off-duty applies, and Brainy when we're being all official and codename-y. Sidebar: I am really, hilariously bad at using codenames when a teammate's life is in danger, so you try not to be in peril where I can see unless you're down with everybody knowing your real name.

Or, you know, where I can't see. Because I'll find out and lecture you later.
