If you were a b-list supervillain, who would you be?

[DHBirr]

if Armada can lift something he is standing on.

Alas, one thing I specifically determined when I imagined these characters -- years ago; I didn't come up with these just now -- was that Armada can't self-lift.

Armada seems a bit too... well, credible threat, for the b-list, espescially if he's good enough to be a mastermind's favored right hand.

"Favored right hand" is giving him too much credit.  Zeta Prime isn't just a Gadgeteer Genius; he's got "bags of crisma," as Sergeant Colon would say it, and if he and David Xanatos existed in the same universe, they'd probably consider each other the most interestingly challenging chess opponents -- between attempts to kill one another, of course.  Armada is just an occasionally useful mercenary, and ZP's sense of honor won't let him betray someone without making some form of recompense. 
Also, Armada is content to be relatively small-time.
