History[]
Scooby-Doo! World of Mystery[]
He ran off the bridge and hid in one of the nearby rooms when the alien was attacking, and later met the gang when they were rescued by the bridge guard and introduced himself, he accidently sneezed when Scooby got close, to which he apologized saying he's allergic to dog. And then left the room soon after.

The chief engineer revealed.
He was later revealed controlling the alien, thanks to his allergies towards dogs causing him to sneeze so hard that the robot fell apart. He climbed out angry at how his allergies ruined everything, he was so annoyed with it that he didn't pay attention where he was walking and caught his legs on some rope, and then fell off the top of the bridge all the way down to the road, but the rope ended up tightening around his ankles leaving him suspended in the air just before he hit the ground.
The rest of his plan was explained by the rest of the gang and he was then fired by the bridge guard and arrested by two police officers.
