Even angels can be bad

I thought of another idea that might be better, but I'll let you pick xD So I have Neptune who is a year old now I think and he's been on his own since he was really little because his parents passed away. He's generally kind hearted, but he's also very naive and probably easily manipulated. I actually made him as a lone pup and made his personality pretty open so his threads could shape him, but nothing has really happened with him yet. So maybe Rikeros can mold him to be darker? I'm down with Neptune taking Rikeros' name if an adoption plot would be in the works!
