So my first sons, LOCW, is kind of aloof at times, and is "lawful good," to use internet meme stuff! He's serious unless he's alone with his friends; then he can be pretty funny. He's selfless and a very good leader.
Jedi would be the "chaotic good", but he's still super loyal and faithful. He loves pranks and being ridiculous and at times rather annoying! He's quite sensitive though. He's also pretty fearless and, against all odds, wise for his age. He can sometimes say rather tactless things, though. That's usually due to him not always knowing people's history because he isn't nosy, though. He's a very good friend to have, even if he is the Sarcasm Master.
Evan is a "neutral good" guy, but he's got serious self esteem issues. His friends have been helping him through it. You'll never find anyone more selfless and loyal; he has died for his friends about 8 times with no thought for himself. He's very sweet and innocent, and rather immature when he's around friends. That's because he never really got a childhood. He's fun and brave though, and a bit sarcastic.
They have these personalities not because I chose them (honestly Evan and Jedi turned out way different than I thought they would when I designed them!) but because they chose them for themselves.
