Makeo

Makeois an android-saiyan hybrid and antagonist-turned-protagonist of Dragon Ball: Forgotten Age.

Makeo began as a project to recreate the power of Takama. At the age of 12, he snuck into Takama's aging machine, also becoming 16. Eventually he began to battle Takama in the Makeo's Path Arc, however he began to become a protagonist around the God of the Universe Arc, at this point Takama's full on friendly rival.

In Rukia's Arc, he and Rukia begin to have feelings for each other after their initial encounter. Eventually this, mixed along with the fact that he was more friendly now, has him turn into a full fledged protagonist, rather than a deuteragonist.

He is the winner of the Battle of X and plays a prominent role in the Battle of X Arc.
