He was first seen in episode 13: Mario Bravado. Eli used him to free Pronto. Stuntz has special goggles in which he uses to calculate precise angles. He is friendly, but mischievous by nature.
- Protoform Abilities - Can curl up like a pinball and bounce around to hit a small target.
- Trickoshey - Calculates angles to ricochet off walls and hit hard-to-reach targets - good against blocking moves.
- Unlike other Speedstingers, Stuntz has orange highlights on his shell and has goggles.
- When he transforms, his goggles grow with him.
- In "Light as Day", Stuntz was the first slug shown to not be experienced enough to do a Mega Morph shot.
