==Character History==
===Bugster Ordeal===
Nishiwaki was infected by Graphite, who subsequently kidnapped his sister to aggravate Nishiwaki's stress. The coroner was found quickly by his co-worker Kiriya Kujo. His infection flared into a spiked wheel Bugster Union that was destroyed by Lazer Bike Gamer Level 1, releasing the Motors Bugster. Motors was soon destroyed and Yoshitaka cured by Ex-Aid and Lazer Action and Bike Gamers Level 2. 
===Kiriya's Absence===
Sometime after Kiriya's death, of which Nishiwaki was unaware of, he would later pass on Kiriya's belongings to Hiiro Kagami, including his laptop which contained important data required to complete the Maximum Mighty X Gashat. 
==Forms==
The is the monster form of a Bugster-infected patient when the virus first flares up. When a Bugster-infected patient experiences enough stress, the Bugster Viruses inside multiply rapidly and overtake the patient's body, forming a giant orange virus form around it; the Union's shape seems largely irrelevant to the Bugster's appearance. Bugster Unions can only be defeated by a Kamen Rider in Level 1; the reason why is unexplained, though it may be because other Levels are too strong and may injure the patient inside the Union.
