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. Furthermore, 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 Fellands, where she would be sealed by the Synergy Stones. Years later, Chloromia has managed to escape from the Fellands 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.

Newcomers

 * Chloromia: The antagonist of the game. She is the Ruin Princess who was freed from her Fellands prison and aims to conquer the worlds once again. She appears both as a playable character and the final boss of this game. Chloromia controls crystals and can summon scythes at will.
 * Denise Falter: A former member of the Dust Rats, as well as Lyle's girlfriend. She journeyed to the east after meeting her boyfriend and his partner, Bartz. Now they team up with Meixiu in her battle against Chloromia. Denise can channel energy in her feet to grant her super speed, which requires concentration.
 * Iceldo:  The mysterious evil sorcerer who helped Chloromia escape from the Felllands. In exchange for his services Chloromia has granted Iceldo the position of arch-sorcerer of the now expanded Fellands. Iceldo is the sub-boss of the game, and he possesses black magic and psychokinesis.
 * Kelti: A traitor to the planet Eveia. As the daughter of the world's ambassador, she invited a group of escapees fleeing their own world into the tranquil Eveia. But once Queen Natwan allowed them through the portal, she learned that one of the warriors was none other than the banished Ruin Princess, Chloromia. Kelti is known for her preferred fighting style, the "Wandering Sloth," where she fools her opponents with her slow movements.
 * Otiz: A general working for Chloromia, who lead the forces of darkness into the battle against Xifan. Once thought to have been killed during that onslaught, he resurfaces and joins the battle against Earth's forces. Otiz carries several weapons at his disposal.
 * Tao: Meixiu's ally, a Chinese lion spirit. Their ascendants were defeated in a war of the Cosmos between Chloromia's forces and the Superiors. Now assuming a human form, he prepares for the final battle between the Forces of Light and Chloromia's warriors of ruin. Tao is capable of performing lion magic, based solely on fire.
 * Veggy: A humanoid plant-like creature. (Unlockable)
 * Zet: The last member of the Blood Dinosaurs after the assumed death of Stabber. He has since been hunted down by Force Ranger Ivy Ross for crimes against humanity. With the emergence of a powerful evil, she focuses her strength on Iceldo. Zet meanwhile finds himself fighting alongside Ivy and Earth's warriors to help defeat Chloromia. Zet possesses the same weapons Stabber once had.
