A powerful red T-Trux with crushing jaws and a wrecking-ball tail. Ty is brave, warmhearted, and determined to build a community where size and species never decide someone’s worth. He leads the valley expedition, but protecting everyone can make him take on too much. He listens to practical advice and earns loyalty through his actions.

A small yellow-and-green rotary-drill Reptool and Ty’s closest friend. Clever, curious, and precise, Revvit repairs machinery and turns difficult problems into workable plans. The abandoned valley structures fascinate him, though his excitement sometimes distracts him from danger. He values small contributions as much as enormous feats of strength.

She helps map routes through the valley and speaks up when excitement threatens the crew’s judgment. Her teasing hides genuine affection for her friends.

She organizes demanding repairs and refuses to let larger creatures overlook the tools’ contributions. In the valley, she pushes for dependable equipment and plans that survive actual use.

Proud, intimidating, and fiercely competitive with Ty, D-Structs views the valley’s ore as the foundation of a new domain. His aggressive construction threatens shared routes and habitats. His rivalry concerns Ty’s community; his relationship with Guest develops through their own choices.

A small welding-torch Scraptool responsible for keeping D-Structs operational.
