Dimension Phasers

Power Batlers 4 is the fourth main installment of the series and the seventh game overall produced by Burst Arts and published by Namco. It was the first game to never see an arcade release. Instead it was released for the PlayStation 2 and Nintendo GameCube in 2004. An updated version titled Power Battlers 4 Extreme was released the following year for the same consoles, in addition to the Xbox and PC.

Gameplay
Power Battlers 4 retains the same gameplay from the Revolution games, including the Synergy Stones from the 3rd game, but with some changes. Power Battlers 4 introduces a limited power form system, allowing each character to assume a stronger form using a set button combination. This is only available if the player is under the possession of a Synergy Stone. Futhermore, there is a meter underneath the health gauge, decreasing as the player has their powered form. When the player is attacked, the meter decreases faster than usual. Aside from that, Power Battlers 4 also introduces sidestepping, reminiscent of SNK's Fatal Fury titles. Players can jump to the background or foreground of most stages.

Story
Thousands of years before the setting of the first game, Chloromia, known throughout the six worlds as the Ruin Princess, attempted to become the conqueror of them all. Meixiu's ancestor, Xifan, fought and defeated Chloromia in a war that lasted for hundreds of years, sending her to the Felllands, where she would be sealed by the Synergy Stones. Years later, Chloromia has managed to escape from the Felllands with help from the sorcerer Iceldo, and seeks vengeance against her banisher's successor, Meixiu. She enacts her plan by conquering Eveia, with the help of the traitor Kelti, while she prepares to kill Meixiu. Meixiu herself requests help from the heroes of the Earthlands who saved the worlds from King Benmatsu.
