Trantoshen (OU)

Trantoshen was created by Kakamu with a Genetic Manipulator given to him by User KoN. He left the Matoran Universe some time before Kakamu became a Makuta. When he heard that his father was dead, he vowed to destroy all Makuta. He somehow found his way into the realm of shadows and he got the Kanohi Daran and the Guardian Fire Spear.

Some time later, he discovered a Makuta named Klak. While trying to destroy him, Trantoshen was knocked to the floor by TMV. They fought.

Suddenly, the Fellowship of Kakamu appeared out of nowhere and kidnapped him, believing that they had found Kakamu.

When Kakamu was revived, he took over Trantoshen's body.

Because Kakamu was in Trantoshen's body when he teleported inside concrete, Trantoshen was technically trapped too.

He later went with Kakamu and Nosmailliw to fight Blackout at the Mata Nui II. During the battle, Genetoes kicked Trantoshen high in the air, and the Toa landed on Parkin.

He did a lot of stuff after that. At some point, he ended up inside the Wigwam, tried to fight Barricade on board Darkmount, was thrown out and fell towards the planet below, had his parachute destroyed, was attacked by Daleks, and was pulled into the Shattered Mirror by strange beings. He was then confronted by his Shattered Mirror incarnation.

Trantoshen later escaped from the Shattered Mirror Universe and came to his father when he sacrificed his life force to destroy Blackout's titan form. Afterwards, he met Yon. Yon tried to kill him but it ended up in them both falling into a plothole. They later escaped.

During the events of the Uterio War, Trantoshen was a part of the Rebel Alliance and fought in some of the many wars with Klak, Treveya and Nadle. One of the more notable battles he was part of was the Battle of Krustallos, where he commanded a squad of Malchiorian soldiers.

After the war had ended and he was reunited with his father, who returned with a new biometal body, he fled with him alongside Muta and Mocax to a planet far far away. On this new planet, his father built a new laboratory for himself deep underground while Trantoshen and Mocax journeyed to the surface. Once they emerged, they were worshipped as "arena gods" by the planet's inhabitants and forced to fight a Zahgargak.
