Notes
- Gairyū corresponds with 鎧竜 in Japanese, meaning "Ankylosaurus".
- The Dinoforce shells are notable for developing a green patina on the painted-gold portions, as well as a slimy texture over their whole surface over time. What causes this is unknown, but ick. Even previously-unopened samples will develop this nastiness. While some water and a little bit of hand-soap should take care of the slime, there's not much to be done about the green discoloration.
- The Victory anime depicted the Dinoforce members as carrying melee weapons, rather than the blasters the toys actually came with.
Foreign names
- English: Bristleback (Omni Productions dub)
