　Prototype　　　　　　　　　Final Version

He's a rather violent character who is quick and strong, tends to fight people who make annoying remarks with his special attack “bodafone” (暴打フォン)⁴⁾ which is just a ground-and-pound, and mysteriously carries the body to Area 51.⁵⁾ In the past, he'd fight with Hageshiku Ninja. Nowadays, he works in delivery or as a teacher. Despite his fixed expression, his face cheeks can be changed to “*”, “；”, or “＃”.⁶⁾

• Kukkuru is said to have god-like strength, like Hahaja to the Sasuga Brothers.
• The beak is actually an element/member symbol in set mathematics.
• Some users nicknamed him “Chicken George” (チキン・ジョージ) which references the superhuman chicken man who terrorizes humanity in Kazuo Umezu's science fiction manga, Fourteen.
• In the baseball boards, Kukkuru was once used for Takashi Toritani who was nicknamed “bird”.
  • Toritani had played for the Hanshin Tigers from 2004 to 2019, then he became a free agent and briefly joined the Chiba Lotte Marines before retiring in 2022 to be a commentator.
• Kukkuru is the rooster at Shobon Action's fake ending, standing next to a pipe that would theoretically lead to Area 51 as the joke goes. You're supposed to go over him, if you haven't figured that out.
