TV Special
Description
Brocken Jr., son of the brutal German chojin Brockenman, endured a strict upbringing defined by harsh training methods. His father demanded to be called "Lehrer," not "father," forcing Brocken Jr. to perform weighted arm exercises over flames to master their family technique. This forged a complex relationship where Brocken Jr. respected his father as a trainer but rejected many of his beliefs.

Initially appearing in a Nazi-style uniform inherited from Brockenman, his imagery was later adapted across media into a generic military uniform, with swastikas replaced by eagles or skulls. After Brockenman's death at Ramenman's hands, Brocken Jr. sought vengeance. He joined the justice chojin assembled by Beansman to defend Planet Rakka from Black King's Space Samurai, prioritizing the mission over immediate revenge against Ramenman, revealing an early sense of duty and underlying morals.

His defining shift occurred during the 21st Chojin Olympics. Following a brutal concrete ring match against Ramenman where Brocken Jr. used his father's techniques but lost, Ramenman spared him. This act, coupled with a pivotal confrontation later that night in the Hakone mountains on the anniversary of Brockenman's death, led Brocken Jr. to abandon his vengeance quest. Guided by Ramenman, he embraced justice, forming a lasting mentor-pupil bond. He transitioned from a brutal style to a dedicated justice chojin, though he occasionally reverted to aggression when needed.

Brocken Jr. consistently supported Kinnikuman and the justice chojin in later conflicts, fighting adversaries like The Ninja and displaying resilience. During the Survivor Match for the Kinniku Throne, he swore absolute loyalty to Ataru Kinniku (Kinnikuman Soldier), serving as Second-in-Command of Team Soldier. In a six-man tag match, he performed a supreme act of loyalty: removing his Totenkopf skull badge – the source of his chojin powers – to revert to human form and shield Ataru from Prisman's Rainbow Shower beam, which only affected chojin bodies. After sunset weakened the beam, he executed his Bremen Sunset technique to eliminate Prisman, falling to his death. He was later revived by Kinnikuman's Face Flash.

After these events, he returned to Germany directionless and succumbed to alcoholism. He found new purpose discovering Jade, an orphaned child. Unofficially adopting Jade, Brocken Jr. became his "Lehrer," rigorously training him for seven years. Their bond deepened into a father-son relationship, with Jade deeply devoted. Brocken Jr. imparted his techniques, including the Red Rain of Berlin, to Jade.

His abilities stem from the Totenkopf, enabling transformation from human to chojin. Signature techniques include the Red Rain of Berlin (a high-speed hand slash causing bloody wounds), Black Fog of Hamburg (a handstand flip kick), Bremen Sunset (a headfirst divebomb), and variations of holds like the Camel Clutch and German Suplex. His fighting style blends speed and precision, utilizing forward-moving strikes and counter-pokes effectively. Controversy surrounding his initial character design led to adaptations downplaying specific elements and emphasizing his justice-oriented role.
