Part monster machine, part triceratops, Zeg is Blaze's best prehistoric pal. Zeg's favorite activities are smashing and bashing. But despite his brute tendencies, inside Zeg is a big softy with a gentle demeanor and a loveable laugh.
Zeg loves to smash since he's a loveable dinosaur truck
According to the Nick Jr site, Zeg is half-monster truck, half-Triceratops.

However, later on, there has been some evidence that Zeg came from an egg, like for example, "Zeg and the Egg" an egg hatched to into a baby truckodactyl. Thus it's further implied that, Monster Machines are born, not built.
