"Four-Arms: What is it waiting for?
Strike: (Laughs) Me.
Strike: I programmed old blasty here to corner you—not to destroy you.
Four-Arms: Oh. Phew!
Strike: (Chuckles) I'm gonna do that myself."
- Strike after cornering the heroes.
"And now to start my incredibly long, un-interruptible power-up sequence. Ra-a-a-a-a-a..."

"...a-a-a-ah‼ There. Fully powered and ready to face heroes who are powerless. Now...huh? Where'd they go?"
