He challenged Ikki with the "Devil's Thirty Thirty", a stunt that normally involves jumping over the bodies of thirty-three of one's teammates; in Ikki's case, he has to leap over Ringo who was lying at the end of the track.

Yoshitsune's Ram Jet Theory based Regalia intercepted and completely nullified the fang. Ultimately, Ikki successfully tackled the challenge, and Trident agreed to collaborate with Genesis.
