Subtitle: Transformation Super-beast (変身超獣 Henshin Chōjū)
- Height: 63 m
- Weight: 46,000 t
- Origin: Yapool's Dimension
Brocken was created by Yapool in his laboratory by combining the bodies of an crocodile with an unknown space creature, merging them to form a new choju. Yapool then sent Brocken aboard a space vessel, that was heading home to Earth, hijacking it in the process and possessing one of the crew members, Koyama. While in its host's body Brocken appeared to act normal, but once his host's son found an extra mouth on his hand the guise was revealed. The son informed TAC, who were quick to take action. When Brocken was found out, he fled TAC until he reached one of their HQs, where he took his true monstrous form and attacked the city with his flames. TAC quickly responded with their gunfire and jets, but they were no match for Brocken's strength. During the fray, Hokuto was caught in Brocken's right arm jaws. Minami ejected from her jet and together they transformed into Ultraman Ace, severing Brocken's right arm in the process. At first, Brocken had the upper hand in the battle with its brute strength and laser attack. Then an Ultra Sign was sent by the 4 Ultra Brothers which encouraged Ace, who managed to stand, and destroy the choju with three Ultra Guillotines, severing Brocken's head, arm, and whips, killing the choju. With Brocken dead, his host was soon free of the monster's control.
- Brocken's roars are modified elephant trumpets. They would later be used and modified for the Toho Monster, Titanosaurus.
- There is a brief continuity error during the battle between Ace and Brocken. When using his claw lasers, Brocken has both from his front arms even though one was destroyed when Ace transformed.
- Although not physically seen, Brocken is one of the monsters that makes up Beryudora's Body in Mega Monster Battle: Ultra Galaxy Legends The Movie.
- Brocken's design and suit are very similar to Dodongo from Ultraman.
- He looks like another of Yapool's chojus, Jumbo King.
