Robotboy, Robotman and Robotbird (younger brothers)
Protoboy was created by Dr. Moshimo in his earlier years. He had many of the same qualities as Robotboy, especially advanced fighting skills, but he lacked Robotboy's humanity. He was stolen by a young Dr. Kamikazi and Constantine. Kamikazi reprogrammed Protoboy's circuits and turned him evil, however, Kamikaze made Protoboy too evil and couldn't control him. Protoboy was disconnected by Constantine and placed in a reject closet. In the episode Brother, after hearing about Protoboy, Robotboy, being sad that he had no family of his own, traveled to Kamikaze's lair and re-activated Protoboy, who then began destroying the city. When Robotboy used Super-Activation, Protoboy did as well. Robotboy was nearly defeated until he used the new weapon Dr. Moshimo gave him, which is essentially a limpet mine. As a result, Protoboy exploded and wasn't seen again until 'The Old Switcharobot' when he switched bodies with Robotboy (only ending up with Robotboy's circuits by accident. This is also the episode in which Robotboy receives his unbreakable armour. He then returned in 'The Revenge of Protoboy' when he nearly disabled Robotboy, tried to sink a cruise ship that Tommy's parents were on. When Robotboy played possum after he fell into the sea, he ripped Protoboy's circuits out. Protoboy then deactivated and fell into the sea.

He melted Robotgirl's batteries and almost defeated all three of them, but was foiled when Robotboy broke free and destroyed the bridge that Protoboy was standing on. Protoboy seemed to have melted in molten lava he used to try to destroy Moshimo and his brother, but is not shown falling in. Protoboy could have made a great brother if he wasn't turned evil. He is stronger than robotboy but he doesn't get any updates his smarts is almost as great as Dr. Moshimo. Protoboy can be captured while he's turned off and re-programed. When he super-activates, he is very similar to Robotboy except for being gold, having a wider head, smaller hands, and for having a large blaster on one of his hands. When provoked, he can have a gatling gun on his shoulder similar to the war machine. Protoboy has been destroyed multiple times and once was deactivated. It is unknown how he is able to return later as Protoboy has simply stated that he is very difficult to destroy.
Moshimo's nemesis. He was originally named Brian and was born from Moshimo's prized milk yak. Unfortunately, he wasn't very smart, which to a lot of ridicule from other yaks and a young Dr. Kamikazi. Moshimo hated the poor treatment Brian got so he performed Brain surgery on Brian which he learned from comics. Unfortunately, this made Brian too smart for the yaks. He ran away the next night, leaving a note telling Moshimo it's his fault he became a freak and that he hates him. Eventually he changed his name to Brain-Yak and was forced to sell test answers to school children as adults don't like a smarty-pants. He joined forces with Kamikazi who promised that Brian could destroy Moshimo for ruining his life. He lost his temper when he realized he was used by Kamikazi to get Robotboy. He was saved on Moshimo's orders. He told Brian he never saw Brian as an enemy. Brian was close to forgiving him until he was taken back to the farm he grew up in. He returned to save Moshimo from Protoboy disguised as Robotboy as he didn't want anyone to destroy Moshimo but himself. He made a cameo in "A Tale of Two Geniuses".
