According to a recent Tweet by Yonkou Productions, it seems like that Jump Force is starring some great characters. Those include Cell and Piccolo from Dragon Ball; Makoto Shishio and Himura Kenshin from Rurouni Kenshin. Light Yagami and Ryuk from Death Note are appearing as well. Though Kenshin's appearance has been rumored recently, it is still not certain because of a controversy involving the manga's original author.

Both Shishio and Kenshin look precisely how the anime featured them, adding some Jump Force-like factors. There appear to be a few details about how these 2 will be able to perform in the fighting game as well. It seems like that Shishio will showcase some Fire-styled moves that have always been a feature of him. On the other hand, Kenshin will be given some special abilities focusing on his speed, which of course, reminds us of the manga.

It seems like Shishio and Kenshin are getting a lot of attention.

Cell and Piccolo don't have as much of a spotlight, appearing along with Frieza as well as Vegeta. However, we can still see Cell appears to be pretty fearful and impressively deadly while Piccolo is in his famous custom. There is nothing revealed about the couple's abilities yet. However, based on the wide appearance of them in an incredible amount of other fighting games, we can have a mere imagination of how this couple will perform.

The appearance of Light Yagami and Ryuk from Death Note is also really notable as mentioned in the Tweet. However, what they are capable of is unclear and we can only wait for more details from the developers.

Jump Force is a fighting game which will be released by Bandai Namco in February 2019 on PS4, Xbox One, and PC.
