- Mandark: Excellent! My sneaky ways have put me in the lead! I'd give myself a pat on the back, but I'm driving, so I'll have to do it later!
- Mandark: My name is Mandark and I am Dexter's rival. He and I have been competing in science and other things for years and this race is just one more of those things where we try to beat each other, except I try to win by being sneaky and bad! My plan this time is to sabotage the Mark 5, so it doesn'twork as good as it should, then when Dexter is racing he'll most likely crash up, leaving room for me to win!
- Mandark: Gather round, all you mortals, and behold the fury that you cannot deny! And you won't be disappointed, either.
- Mandark: Ooh, ah... Ooh... ooh, ah... I have to beat Dexter, sworn enemy. Have to destroy Dexter's lab. If only Ducky could! Ooh, ah!
