Pluto was one of the representatives of the SSKF who arrived on Ketheres in response to Zekka's call to fill out the reserve roster spots for the Space Karate Forces prior to the Block-B Semifinals. During the free for all that Zekka had all the karatekas who showed up undertake as a means of trying out, Pluto first fought a dog-headed karateka, managing to survive the first ten minutes of the brawl. Taraba then leaped into the air and impacted the ground with Squilla Blow, throwing several karatekas into the air and throwing up a massive mushroom cloud. Pluto and Cube then challenged him, but he fended off their attacks with Super-carapace Sanchin. The technique blew them both back, with Pluto losing the lower half of his left leg and Cube his right arm.
