So, I just watching the episode of Danny Phantom in which he fights his alternate future self and I had a idea for a one one one roleplay. 

Dark Dan, Danny's alternate future evil self after being held captive for a few years by the ghost of time name Clockwork proposes a new idea to Clockwork. Dark Dan offers to help his younger self become better at fighting ghosts and take the the teenager under his wing. Clockwork hesitantly agrees and releases Dark Dan to train young Danny, on the condition that the training is monitored, so Dark Dan doesn't try to force young Danny to turn into him.

Please comment on the thread if you are interested in doing this.
