Help with personal saga.

[Hellfighter 17]

I am trying to become a better RPer so I am going to start a personal saga but i will need someone to help me. My character wants to become the strongest fighter in the universe and kill anyone who gets in his way. I'm going to base a saga around that. My character is so over-confident that he thinks he can beat anyone. He well encounter somebody stronger than him and lose. Than that person will train, I would prefer a neutral kind of character to help me.
