KIIBO is a polite and serious robot boy, who has some trouble with human social interaction. Which often comes across as unintentionally comical as a result. Yes, KIIBO is a robot, but he will be quick to assure you that he's just like any other guy. He does take pride in being a robot, and is more than happy to educate and answer questions about what being a robot is like, but he absolutely will not condone any name calling or robophobia.

He is actually far more insecure than you'd think - possibly being self conscious that his robot form doesn't have any of the cool abilities people are quick to ask him about, like lasers or jet powered flight. He would honestly rather be a normal, every day robot instead of something fantastical like that. He is working to understand what it means to be human, and act like how everyday teenagers would. 

He is very well meaning and kind, genuinely wanting to be friends with everyone he can, even though he often ends up as the butt of people's jokes. Which isn't helped by his somewhat oversensitive and wimpy reactions. But he gets increasingly confident as time goes on, even to the point of motivating others towards hope.
