Just watch him train. May be in a series soon.
The Clone Mirage is actually a bunch of afterimages. yes he uses that technique. he attacks in them and trough them to make it seem like there are actually a lot of him. The Bloodwrath is similar to the Kaioken but only lasts twenty minutes max and can only be done once a day and doesn't burn up the user. He can also use the Kaioken, by the way.
