One-Eyed Tyhrranoid

One-Eyed Tyhrranoids were Tyhrranoids with just one eye. These little terrors gnashed at Ratchet with their razor-sharp teeth (which made these the only Tyhrannoids that attacked without any actual weaponry), then jumped back to avoid a retaliatory attack. Ratchet turned into one of these via the TyhrraGuise, but this type of Tyhrranoid was the only one Ratchet turned into.

One-Eyed Robonoid
The One-Eyed Robonoid was converted into metallic machine by Dr. Nefarious with his Biobliterator. These once organic life forms were now purely made of alloys and circuit chips. While their attack patterns stayed the same they were much more powerful, and had strong metallic armor where there once was tough hide. Plus, unfortunately they were much smarter and harder to trick when you were using the Tyhrraguise.
