Akidroh Avunakat is a character from the BIONICLE SAGA series.
Akidroh hides his past from others, but helps anyone who needs help, especially from Visorak. He reads every night The Chronicler's Book in his room. He rescued The Six Matoran before they were mutated by Visorak.
He wears a golden Kraahkan and has a multi-coloured body.
If you look closely, you'll see his body is made of the colours of the six elements, and also yellow, the colour of light. That may give you a bit of info about his past.
