Dozer is an aggressive, brave and cranky Dozeratops with a soft heart hidden under a hard exterior and a "hit first-think later" kind of attitude who likes doing dangerous things. At first he hated Ty Rux as much as he did D-Structs, but after Ty and the other Dinotrux rescued him from a tar pit he became their friend, although he has a rivalry of sorts with Skya, who is a Craneosaur. He once claimed to have been a single egg and used to be best friends with Blayde until D-Structs attacked, turning her against her own herd.
"One T-Trux is bad enough. We don't need two."
"LET'S TURN THEM INTO A PILE OF SCRAP METAL!"
