Bandai Namco revealed in this week’s issue of Jump magazine that Dragon Ball Fusions will feature Dr. Slump’s Arale as a Fusion partner. [Thanks, @Kazu4281.]
The Jump scan shows us an “EX Fusion” character named “Towale,” a fusion between Arale and Towa.
Dragon Ball Fusions will release in Japan on August 4, 2016 for Nintendo 3DS.
