Mega Man Star Force 2

Mega Man Star Force 2: Zerker × Ninja and Mega Man Star Force 2: Zerker × Saurian are action role-playing games developed by Capcom for the Nintendo DS. It is the sequel to Mega Man Star Force and the second game in the Mega Man Star Force trilogy. The game was first confirmed on April 12, 2007 in an issue of CoroCoro Comic. The same issue also revealed that a boss design contest would be held exclusively in Japan much like the same contests held for the Battle Network games. A sequel, Mega Man Star Force 3, was released on November 13, 2008 in Japan.

In a similar format to Mega Man Battle Network 5: Double Team DS, each game card contains two versions of the game, available as Zerker × Ninja (ベルセルク×シノビ, Berserk × Shinobi) and Zerker × Saurian (ベルセルク×ダイナソー, Berserk × Dinosaur). Both versions were later compiled in Mega Man Star Force Legacy Collection (2026).
