This episode introduced Premier Dutch or at least a look-alike android. The Plago race (in it's normal form) is introduced in this episode, as well.
Lazarus Slade: At long last, BETA Mountain is mine! (seeing the hatch is barred) We'll need a battering ram, something incredibly thick, and hard. (points at a Plago) You!
Buzzwang: (as everyone passes out from Slade's gas attack) What a rotten day this turned out to be.
Lazarus Slade: (addressing his troops) I know what's been said about you Plagos: that you lack military discipline, that you're lazy, and weird, and that you just can't cut it. But they are wrong! Right?!
Plago One: Right, right!
Lazarus Slade: We're the roughest, toughest, deadliest force in the universe! Right?! (the Plagos all stand blinking at him) RIGHT?!
