Portaltron

Portaltron was a minor antagonist in season 2 and reappeared briefly in season 3. Little is known of the alien cyborg known as portaltron. Portaltron's body received numerous technological enhancements at one point in his life. Due to this he became more machine than human and rarely shows emotion. Portaltron spent the rest of his life working as a mercenary for various people around the umiverse. One day he would receive a contract from Ancestor Skeletor. Portaltron focused his sights on Skeletor and travelled to earth in search of him. Portaltron eventually found skeletor but realised that he was now accompanied by two friends, Zombie Skeletor and Skelewoman. Portaltron put up a fight but the three of them made short work of him. The beating caused Portaltron to shut down, leaving him dormant but still alive. His body would later be sent to FuturScience Industries where John encounters him once again three years later. Portaltron woke up from his dormant state after being repaired by scientists and went looking for Skeletor once again. Portaltron decided to leave Skeletor alone after realising that three years have passed and that killing him would be pointless. He leaves earth after this to an uncertain fate.

Powers
Portaltron became a cyborg after receiving a lot enhancements to his body. His skeleton and skin have been replaced with a metal-like material from a distant planet. Portaltron is quite durable as a result of this and can take quite a lot of punishment before dying. His most valuable tool is the portal gun which is welded to his arm. This prototype gun can create portals which lead to various areas around the universe. Portaltron also possesses a couple of alien projectile weapons.

Personality
Portaltron never had the luxury of a family and spent most of his life trying to earn a living as a mercenary for hire. He became almost emotionless after becoming a cyborg and was very much like a machine. The only time he ever shows emotion is when Skeletor reveals that his contract giver is dead and gives him a chance to leave without any trouble. This causes Portaltron to tell Skeletor the sad tale of his existence. For the first time Portaltron realises that he has no family and friends and this causes him to feel disheartened.
