He is carefree and good natured. However, he tends to get manipulated and tricked into situations. Relying most of the time on luck, Sarrok's brother isn't the smartest but isn't a full blown moron."Barrok Series"
Barrok is one of the oldest characters that Larnuu has made. When made, Larnuu had intended for a "Barrok Series" but then Gako and Rio came a long. He did not want to scrap the character so he decided to just make him a big role.
The "Barrok Series" was going to be about Barrock and his life at work, (co stars were going to be Sarrock and Kerrog). However, Larnuu did not scrap the concept and incorporated some aspects in "Gako and Rio".
