The four-eyed tyhrranoid, also known as a Tyhrranoid Commander, was a type of Tyhrranoid encountered in Up Your Arsenal. The largest type of common Tyhrranoid, they were also the strongest, often leading other Tyhrranoids in battle or holding important positions. Their robonoid version is called the four-eyed robonoid, with the later version being called four-eyed robonoid V2.
First encountered at Holostar Studios, they commonly appear in pairs or in company of a group of Three-Eyed Tyhrranoids. They appear to often have a role in guarding passageways. On Kerwan they were converted into robonoids by the Biobliterator. These robonoids appear again at Aridia, during the Operation: DEATH VALLEY operation by the Galactic Rangers. Lastly their final version, the robonoid V2, was seen guarding the command center on planet Mylon.
Easily larger than the 3-eyed tyhrranoid, the 4-eyed is easily visible by their skin color, which is bright green, except for their beige-colored abdomen. Four eye stalks rise from the top of their torso, above a large mouth, with misaligned teeth and a large underbite. On Kerwan they also will wear additional armor panels on their shoulders. The four-eyed robonoid had a more olive green color to its plating, whereas the V2 variant had an almost entirely black design, with only the arms being a metallic gray.
The four-eyed Tyhrranoids were armed with a large pistol that shot long-distance blasts of plasma. The pistol could only fire five shots in a row, before requiring a reload. They are often-times armed with a jetpack, which allow them to indefinitely remain aerial, until too much damage is taken. The robonoid V2 was the only variant never seen using a jetpack.
The tyhrranoid commander is most dangerous when it either manages to ambush the player, something it can do by utilizing its jetpack to appear out of a window or from below a platform, or when accompanied by other troops. Their pistol has high damage, fire rate and the reload window is relatively short enough that it does not seriously impair them a long enough amount of time. Added to this, their jetpack frees them from any ground-based hazards and their plasma pistols leave short momentary remains of plasma on any surface upon hit, further limiting the player's movement.
On the other hand however, they can relatively simple to dodge by relying on well-timed side flips and make a sufficiently big target that the majority of weapons will be able to damage them. With enough damage their jetpack stops functioning, grounding them and thus opening them up for more avenues of attack. Nonetheless, it is recommended to use any available sufficiently strong weapon such as the Annihilator, Plasma Coil or Disc Blade Gun. Combining these with the Holoshield Glove or Shield Charger is also recommended if there is a lack of available cover. Lastly, it is possible to engage them in close range, as they will attempt to pistol whip you, instead of relying on their firepower. On the inverse, simply taking them out at a distance using the Flux Rifle is also a viable tactic.
