When Tsukioka joined Osaka Pro Wrestling he adopted a masked clown gimmick, the comedic character "Kuishinbo Kamen" who wore a clown suit and even had a hat with yellow pom-poms attached to the mask.

[1] He would return to the ring a week later as ""Super Robo K", a robot gimmick completed with a more mechanical wrestling style.

The character change only lasted for a couple of months before Kurishinbo Kamen returned to the ring.

Kurishinbo Kamen would hold the Battle Royal and the Meibutsu Sekaiichi several times in subsequent years.

[1][2] On June 6, 2010 Kamen teamed up with Ebessan III and Kanjyuro Matsuyama to defeat the team of Atsushi Kotoge, Daisuke Harada and Takoyakida to win the UWA World Trios Championship, holding it for six days before losing it to Tokyo Gurentai (Fujita, Mazada and Nosawa).
