Zeetha's armor in panel five is a nod to Metroid. It's Samus Aran's power armor, and Agatha's comment is a nod to the fact that Samus removing her armor at the end of the first Metroid game was the first indication the player received that Samus was female.
Aha! I'm not much of a gamer, so you have enlightened me.
There's also Sontaran armor in the background, and the metal bikini is reminiscent of one of the NSFL sketches.
Sontaran where? [peers]
