Mechaniloid

The Mechaniloids are a group that appear in the Mega Man comic series, and the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. They are a type of robot from the year 21XX in Mega Man's World, but less advanced in terms of intelligence than a Reploid. Mechaniloids were created for various functions to assist humans and Reploids. Unfortunately, many of them were corrupted by the same virus that turned many Reploids into Mavericks, and as a result became part of Sigma's forces in his bid to take over the world.

Worlds Unite
When the Maverick Hunters attacked Sigma's fortress in an effort to destroy him for good, they were challenged by a small army of Mechaniloids. Upon making his escape to the Lost Hex above Sonic's World, Sigma had Dr. Eggman's Badnik producing facilities there reconfigured to produce Mechaniloids instead. He soon had a veritable army ready to confront the heroes, which he placed under the command of the mind-controlled Deadly Six.
