Bizorm (ビゾーム Bizōmu) was originally a German man named Klaus Eckart (クラウス・エッカルト Kurausu Ekkaruto), a former member of Alchemy Stars. He was part of Project CRISIS alongside Hiroya Fujimiya, but he left the project, stating that he believed that should the Radical Destruction Bringer ever appear, humanity shouldn't try to attack it.
Klaus' reasoning was that if the Destruction Bringer was capable of giving him power then he saw no reason to antagonize it. Klaus had found a way to make contact with the Radical Destruction Bringer through an ancient rune circle. He then joined the Destruction Bringer's forces and became a member of Spirit Parasites, now as Bizorm. He first appeared in Ultraman Gaia episode 42.

Klaus gave a transmission diode to Σ-Zuigul to hack into Gamu Takayama XIG-NAVI. The diode allowed Satanbizor to invade Gamu's dreams in an attempt to psychologically defeat Gamu. However Gamu discovered the diode and suspected Klaus, as he had worked on the Project CRISIS, the project that was dedicated to predicting the arrival of the Radical Destruction Bringer.
Gamu took flight to Germany, and while looking for Klaus he met again with Catherine Ryan, who shared his goal, as she believed Klaus must have meant that it would be a mistake for humanity to try and attack the Destruction Bringer. She explained to Gamu that Klaus had disappeared behind his family's castle in a garden in front of his family. After Gamu discovered Klaus' rune circle, he and Catherine went to the garden were Klaus had disappeared.
There, they encountered the creatures that took Klaus, the Spirit Parasites. One of them appeared in the form of Gamu Takayama and later as Klaus. Klaus explained that he had willingly joined the Destruction Bringer in order to receive power, with the Spirit Parasites then merging with him and becoming Bizorm.
Gamu transformed into Ultraman Gaia and the battle started with two giants fighting with blades of energy. Ultraman Gaia's superior swordsmanship left Bizorm sliced into pieces. However, the pieces quickly transformed into a smaller group of Bizorms, who used their energy beams to bring down Ultraman Gaia. Gaia transformed into Supreme Version while the small Bizorms reformed, the two giants then charged at each other with energy-coated fists whereupon the decisive impact, ended with Bizorm's defeat.
After the battle, Gamu commented that he felt Klaus and him were alike, and that Klaus gave into the same fears he himself had about being an Alchemy Stars.
