How about he takes it up to the next level! Goku is the Super Saiyan God, a power beyond that of the Super Saiyan 3! He has red hair, red eyes, and what looks to be an even more sparkly gold aura. The Super Saiyan God pictures, or rather scans, come from the latest issue of V-Jump. There is also an interview with Akira Toriyama. Please visit the Akira Toriyama Interview (Dragon Ball Z: Battle of Gods) page for an English translation.
