Nine of us came from Lorien.

They killed Number One in Cloudsdale. Number Two in Manehattan. Number Three in Trottingham.

I am Number Four and I am next.

After the third scar appeared, Number Four knew that Three was dead. Burning his stuff and leaving everyone he met in Saddle Arabia behind, he changed his name from Clockwork to Time Turner and moved to Ponyville to hide from the Mogadorians, the alien race out to kill him and the five others remaining. He makes friends with a seemingly nice pegasus named Derpy, makes enemies out of ponies and develops Legacies - special powers that were given to him by his home planet Lorien.

It's going to be one wild ride.
