Dragon Ball Fusions

Dragon Ball Fusions is a role-playing video game for the Nintendo 3DS, based on the Dragon Ball franchise. It was released in Japan on August 4, 2016 with a localized version being released in North America on November 22, 2016. Dragon Ball Fusions was released in Europe, the Middle East, and Australasian territories on February 17, 2017. Dragon Ball Fusions allows players to create their own character, build teams, and collect Dragon Ball characters to fuse and create new ones to use during battles. 

It also allows players to take a photograph of themselves or their friends and fuse them. Unlike other Dragon Ball games in the franchise, Dragon Ball Fusions does not follow the story from the manga or anime. Rather, it revolves around the exploits of the customizable main protagonist Tekka and their friend/rival Pinich who use the Dragon Balls to summon Shenron and wish for the greatest martial arts tournament ever, resulting in the rest of the story to take place.

This wish resulted in the creation of the Timespace Rift, a warped dimension connected to and/or containing locations from various eras/timelines and parallel dimensions like Other World. After being sucked into the Timespace Rift after making their wish, they are informed by Bulma about the Timespace Tournament, a contest where fighters from throughout all the Dragon Ball Timelines come together to fight an see who is the best.

However, before they are able to get to the tournament, they must first make their way through 4 areas connected by Korin’s Tower. Bulma gives Tekka Ziku, a robotic Timespace Radar she developed that she believes will help Tekka in their quest and suggests they seek out Goten and Trunks who were also looking for teammates for the tournament.
