J-Stars: Naruto Uzumaki

Fanmade wallpaper for J-Stars Victory VS of Naruto Uzumaki, composed of my ideas for alternate costumes and transformations. From the scans of J-Stars that I've seen, I assume that the game's gameplay will be a mixture of Budokai Tenkaichi and Ultimate Ninja Storm, sort of in the likes of Tenkaichi Tag-Team or Zenkai Battle Royale. With that in consideration, there's no doubt that characters will be able to transform. As for costumes, both the Naruto and Dragon Ball Z games have had them, so I assume this game would as well. I'll only be suggesting three (Default and two alts) as that may be most likely.
Costumes (Left):
Shippuden: Naruto's default, of course. His modern appearance in the manga and anime.

Menma: The evil Naruto from the Road to Ninja movie. Since he wasn't made a costume in Ultimate Ninja Storm 3, (although may be future DLC), he would be a great choice for one of Naruto's costumes. The fact he originated from film may lessen his chances, but the fact that he was created by series author, Masashi Kishimoto, increases his chance.

Goku Costume: Naruto wearing Goku's outfit. This one is fairly unlikely, but a fan can dream. It was featured as a special DLC costume for Ultimate Ninja Storm 3, and was based off of a sketch by Masashi Kishimoto that appeared in an issue of Jump. It has a higher chance due to the fact that this game has the potential for crossover costumes such as this one.

Transformations:

Sage Mode: One of Naruto's most recently used forms, Sage Mode would be a Stage One form, similar to Goku's Kaioken or, for example, Ichigo's Bankai. This form would mainly be a condition change that would allow Naruto to perform slightly different combos (such as Rasengan Barrage or usage of a throwable Rasen Shuriken), with a bit more knockback. He would also appear wearing the red cloak and scroll, as an homage to Sage Naruto's first and most iconic appearance.

Nine-Tails Chakra Mode: Naruto's newest "favorite" form, Nine-Tails Chakra Mode would be a Stage Two form, among the ranks of Super Saiyan Goku and Hollow Ichigo, and would change his moveset completely. His moves would be much faster and he would have a large variety of Rasengan and teleportation techniques.

Bijuu Mode: Naruto's most powerful form, this would be his Stage 3 transformation. He would still fight within the same style as Chakra Mode, but he would also be able to shift into a secondary Full Bijuu Mode, allowing him to access the full Nine-Tails form for a brief amount of time. In this form, Naruto is able to lash out with the Nine-Tails' claws and tails, as well as perform the Tailed Beast Bomb. As with the manga, however, he will be unable to maintain this form for more than 45 seconds to a minute, and would need around the same amount of time to re-access it.
