Bertram was once a monkey who couldn't talk but when green magic hits him he can talk. Bertram notice that he can summon a Keyblade like his twin brother Matau does. When he is approached by Lord Megatron (from Transformers: Prime), Master Xehanort and other villains, he thought he's getting ready to fight. But Megatron tells him that he wants him to join the Decepticons. Bertram agrees and trains with Xehanort how to use the Keyblade. They capture Arcee's partner Cliffjumper to kill him by stabbing him with his Keyblade. When the Autobots arrived, he snuck up on Matau but his twin hears him coming and fight him in a swordfight. Arcee races to Cliff only to find out that he's been turned into a Terrorcon. Later, Bertram's brother Matau cuts his left arm off with Ryan's lightsaber. Crying in pain, Bertram calls for help and Starscream arrives to get him. Being send to the Medic bay, Bertram uses magic to make his arm immortal and puts it in a case. Knock Out looks at Bertram and asks Bertram what's the matter. Bertram informs Knock Out that Matau has cut his arm off. Knock Out suggests Bertram to rest and give him a sleeping potion. After Bertram falls asleep, Knock Out fits a robot arm on Bertram. When Bertram wakes up, he notice he's got a robot arm. Knock Out informs Bertram that his robot hand has fingers. Suddenly, his robot fingers move and notice Matau walking looking for someone to rescue. Bertram thought Matau would come and apologise but he didn't. Instead Matau needs to find how Megatron plans to use the spacebridge. Bertram gets angry and states he will get revenge on Matau. When Megatron asks Bertram how he will do it, he'll get Ryan and his sister Sari. But Bertram has something special in mind for his twin. Later, Matau notice Bertram is angry and want to apologise. But Bertram tells Matau that he wants revenge and got a surprise for him. He sends Vehicons out to get Matau and Sari. Sari runs while Matau slices the Cons into bits. Bumblebee and Bulkhead arrive and save the two. Bertram's robot arm turns into a rocket launcher and Bulkhead grabs the rocket when it's fired. He swings the rocket and throws at the Vehicon.

He gives the shard to Evil Ryan and walks off. Bertram is happy that he got his Siren pendant and a robot arm. He later reveals to be an Equestrian Siren and a bandmate of the Cyberlings.
