Dan's little brother Trek is a bit of a copycat. He is always following Dan around and trying to get him to play dinosaurs with him. Of course, that's just because Trek idolizes Dan. Dan loves his brother but finds it a bit of a challenge to include him in his dinosaur research. Surprisingly, Trek will usually end up helping Dan out. Trek's innocence usually points out the simple truth of a situation.
Trek has a white bowtie and white shirt. He wears a black coat.
Trek has appeared in most episodes of Dino Dan.
