Tri-Spike Swarmers were robot swarmers. They were very much like the organic alien swarmers. They had spikes extending from their head to their tail and had three large spikes on their forehead. They only attacked by biting. They were extremely weak; a single hit from Ratchet's wrench would kill them. Tri-Spike Swarmers attacked in packs and rarely traveled alone. Judging by their body structure and attack methods, Tri-Spike Swarmers may have been in the same family as Claw Tooth Swarmers and Rhyno Swarmers.
Behind the scenes
