He had three friends, Edd, Tom, and Matt.
Of course, after he left to pursue his adventures and plot to become the red Leader, he became more distanced from them.

Before he became red Leader, he used to be slightly more compassionate and sympathetic. I'm sure that side of him is still in there somewhere. He can also be a tad bit flirty.
