The One-Eyed Tyhrranoids were the smallest variant of Tyhrranoid. Unlike their stronger brethren, they did not use weaponry. They gnashed at Ratchet with razor-sharp teeth, then would jump back to avoid a retaliatory attack.[1] Ratchet could disguise himself as a purple-and-blue One-Eyed Tyhrranoid via the Tyhrraguise; however, it was the only one he could use.

In Secret Agent Clank, they were incarcerated at the Prison Planet and used a roll attack against Ratchet.


One-Eyed Tyhrranoid v2

The One-Eyed Tyhrranoids V2 were tiger-striped Tyhrranoids that were a stronger variant of One-Eyed Tyhrranoids, but otherwise behaved identically. This variant began appearing in Holostar Studios.

One-Eyed Robonoid

These Tyhrranoids were transformed into robots by Nefarious with his Biobliterator. These ex-organic life forms were now purely made of alloys and circuit chips. While their attack patterns remained the same they were now more powerful and had strong metallic armor where there was once tough hide. In this form, they became much smarter than they were before and made them harder to trick while using the Tyhrraguise.

Tyhrranoid Doorkeeper

Tyhrranoid Doorkeepers were teethless versions of the One-Eyed Tyhrranoids, due to this they were the weakest type and were not capable of efficient combat; however, when forced into combat they would utilize a lunging chomp attack. As such they were used by Nefarious to operate his defenses. Ratchet would have to communicate with them using the Tyhrraguise.

After all Tyhrranoids were turned into Robonoids they became One-Eyed Robonoid Doorkeepers, making them smarter and also giving them teeth (making them combat capable), thus making them identical to regular One-Eyed Robonoids.

  • On Holostar Studios, there are falling one-eyed Tyhrranoids on the gravity tower where a Titanium Bolt is. If these are killed by Ratchet, a fast-falling effect shadow is left in mid-air.
