After the misunderstanding of Tein's students thinking Bruce ment harm and Batman owning them then getting owned by Tein Batman explains which has them call Bulma. Bulma says that she can help him but it might take a year in order to do so batman stays with Tein during that year training with him and roshi due to him being fascinated by the concept of ki and Batmans year of training begins.......
-This is current Batman (New 52 and Pre 52 are pretty much the same with a few retcons)
- This Is Dragonball Super(Obviously)
- Batman is not restricted to the dojo hes also free to go to Kami's lookout as well
- Many of the main cast come to see Batman (Yes even Goku Vegeta Weiss and Beerus)
How strong do you think batman would get in compared to Dragon Ball characters?
How strong do you think he'll get in compare to people of he's own universe when he gets back?
