パワーバルタン　Powered Alien Baltan

In Ultraman: The Ultimate Hero, the Baltan appear as Powered Alien Baltan (パワードバルタン星人 Pawādo Barutan Seijin), and their leader, Psycho Alien Baltan (サイコバルタン星人 Saiko Barutan Seijin). They are the main antagonists of this series and are referred to in series as the Baltanians.

Long ago, multiple planets had fallen victim to Baltan's conquest of invasion. Their recent target is Earth and were followed by Ultraman Powered. Arriving nearby Earth, the spaceship sent a trio of agents to Earth in the form of green orbs. However, one of them molted their skin and was analyzed by WINR, losing what stealth capabilities they had.

That night an Alien Baltan was found growing inside of a warehouse in Los Angeles and managed to kill two police officers. Their ship was detected by WINR and attempted to attack the ship but Powered destroyed the satellite first, fearing the Baltans would strike with a stronger counterattack. WINR was soon sent out to exterminate Alien Baltan before he could start a rampage. One of them was hunted by WINR troops and fleeing underground only to meet up with the other two. After being shot at, Alien Baltan grew by fusing with the other two and started attacking Los Angeles.

With the destruction piling up, Ultraman Powered showed up, having recently merged with one of the WINR cadet, Kenichi Kai. As the battle was going on, Alien Baltan fired an energy blast at Powered only for it to be reflected back at him and seemingly destroyed him until he attempted a surprise attack. During Alien Baltan's assault, Powered was charging up the Mega Specium Ray, which destroyed him in one hit.
