As it turns out, last week's speculation is true. Jotaro Kujo and Dio from JoJo's Bizarre Adventure will be available as fighters in the upcoming Jump Force.
This information comes from the most recent issue of Jump magazine, shared by NiniiSpangle on Twitter. A full-color page is dedicated to the reveal, showcasing a few of the fighters' details.
Jotaro utilizes Stand, and can attack with Ora Ora by button mashing into a powerful finishing move. When you play as Dio, you can use the familiar Muda Muda rush attack as well as strike foes with a road roller.
All of this came not long after Namco Bandai teased his inclusion in a vague tweet, which was corroborated by Viz Media, the publisher of the JoJo series.
Jump Force releases for PlayStation 4, Xbox One, and PC on February 15, 2019.
