Yu-Gi-Oh! 5D's episode 097: "Natural Instincts, Part 2"
|Video game debut|
Hermann is a member of Team Catastrophe. He has two criminal marks. Hermann was originally seen when he used the effect of Hidden Knight -Hook- to cause Crow Hogan's Duel Runner to crash (His identity was a mystery for several episodes), thus resulting in Crow's right arm being broke; due to this Crow couldn't enter in the World Racing Grand Prix. He was later seen a long with his team mates Hans and Nicolas smirking at the defeated Team Unicorn, even though they were in danger due to fatal crashes within the Duel Stadium. He was then later seen when Team 5D's were dueling his team within the WRGP. He tried to cause Crow to crash again, but due to Crow's knowledge of the dark card he was able to avoid it's attacks thus causing Hermann to be defeated by him. When he returned to the bay to switch teammates he was greeted by an angry Nicolas who snatched the flag and told him he was useless. The latter along with his Team Mates haven't been seen since.
Hermann uses a Hidden Knight deck which revolves around the Hidden Knights Archetype. He also uses various cards to support the Fiend-type aswell as cards that protect Defense Position Monster Cards such as The Shadow of Dizzying Darkness.
