Akiyama Makuro is the founder of the Hero Factory and is the oldest robot on record.


Makuro's original birthplace is unknown as of now, but in his middle-age he founded the Hero Factory organization after realizing too many crimes had been going across the universe. Makuro succeeded in creating an organization that would allow Heroes to travel across the universe on any mission, at any time needed. He has witnessed the Upgrades the Heroes have gone through from 1.0 to 2.0, from 2.0 to 3.0, and from 3.0 to 4.0. He was present when the Brain Attack occured, and saw the 5.0 upgrade go into effect. He has also seen the Invasion From Below, when certain Heroes were placed in to mechsuits to repel the Jumpers.

Akiyama Makuro, in the Infernum Universe, is well-known for his greatest achievement, Hero Factory. Viewed as a justified, selfless leader, it has never occurred to anyone that Mr. Makuro may have had side projects.

Outwardly, Akiyama is very gentlemanly, and is everything else that is expected of the founder of such a great organization. Behind this front, however, Akiyama is a schemer. Perhaps not outright evil, nor can he be called a villain. But, it is clear that his intentions are geared for his own benefit, nobody else's. The creation of Infernum, a state-of-art prison that became a nightmare, is a testament to that. Though Akiyama did not mean for the prison to transform, neither did he put a stop to it once the prison became sentient.

Akiyama Makuro's story, along with the Tau-4's, will be continued in the Madness Series.



  • An expression was made called "Praise Makuro", and it reflects the BIONICLE phrase "Mata Nui preserve us!"
  • He has also conflicted multiple times with the director of the Makuhero City Police Department, Commander Gordan Yates.
