Click if you read the lightning thief book. Please help me?

I have a project due Monday and its about the lightning thief. I need to make 3 wanted posters about a character in the lightning thief. I already have Medusa and Ares,But if you can give me more information about some bad things they did that would be great. I need the character's name and information about why they are wanted and other bad stuff they did. THANK YOU
