This week’s May 2016 issue of Saikyō Jump in Japan (released 01 April 2016) has announced that Frost and Botamo of Dragon Ball Super‘s Universe 6 will join the Nintendo 3DS game Dragon Ball Z: Extreme Butōden as Z-Assist characters in a forthcoming update.

The quick advertisement focuses on Frost, who is seen delivering a Death Beam-like attack, with a promotional splash stating, “The Evil Emperor of Universe 6 Descends!!!”

The game’s most recent patch in Japan (Version 1.3.0) added yet another four Z-Assist characters on top of the ever-growing list.

Dragon Ball Z: Extreme Butōden launched in Japan 11 June 2015. First-press copies of the game come packed with bonus content, including a downloadable version of the Super Famicom game Dragon Ball Z: Super Butōden 2 (previously included as a part of the J-Legend Retsuden compilation game; albeit now with replacement music). Arc System Works developed the game for Bandai Namco. The developer previously worked on the Bukū… / Supersonic Warriors games on the Nintendo GameBoy Advance and DS.

The game was released in Europe 16 October 2015, in North and Latin America 20 October 2015, and in Brazil 23 October 2015. A free demo is also available on the Nintendo 3DS eShop.

Thus far, none of the game’s patches have been released or localized outside of Japan.
