Arukoitan

The Arukoitan (アルコイタン) is a Reaverbot that only appears on Kattelox Island and Ryship Island, but are very common there. They are mobile and can attack with fireballs or kick the target if the latter is in very close range. The Arukoitan is often paired with an Orudakoitan, which is considered to be the mind while the Arukoitan is the body. If the Orudakoitan is destroyed, the Arukoitan will not function anymore and just stand still, however, the Refractors it yields upon destruction is far less than if they aren't disabled. The Orudakoitan seems to be a radar Reaverbot that sends an alert to the Arukoitan of any intruders. Not all Arukoitans are paired up with an Orudakoitan and vise versa.

In The Misadventures of Tron Bonne there is also one pink/purple Arukoitan called the Koltkoitan (コルトコイタン) with a group of invincible green Arukoitans called the Jeepkoitans (ジープコイタン) are the guardians of one of the Yellow Aurora Stones in the Shala-Kun Ruins. There are few normal Arukoitans in Shala-kun Ruins, and they attack with flames instead of fireballs.
