Skollo is a shy, sensitive and somewhat of a nerd. Skollo never wants to harm or even kill anyone because he's afraid that it might cause karma, so he tries to not to fight. Even if It says so.
Skollo has also been seen playing games of chess with Screen and playing video games. Though, he should be training to make himself stronger with Blorse, Rezwrath and Lezzerd. He believes getting in physical shape isn't important but rather, making your mind stronger and smarter is the way to succeed.
