Icemen

The Icemen (アイスメン, "Aisumen"） is a team of shaman who entered the Shaman Tournament.

About
A trio of shamans from the northern parts of Europe. Training and hardening their pride and duty through the cold, these shaman are notable for their teamwork, using each others abilities to complement one another in order to defeat their opponents. Their pride is initially wounded by Yoh, whose relaxed demeanor and sense of confidence in their match is taken as arrogance.

The team's leader Pino Graham, offended by Yoh's apparent disregard for the Icemen's pride, forces the team to try and prove their own worth in the Shaman Fight. However, the revealed combined power of Yoh, Faust and Ryu make the team realize that they are sorely outmatched and the team is defeated, though Yoh manages to leave their pride intact by not holding back against them despite the evident differences in their power.

After their defeat the group try to leave the island but are attacked by Hao's followers who want to offer their souls to Hao and the Spirit of Fire.

Anime/Manga Difference
The Icemen were shown in one episode and the fight between Funabari Onsen and them was short and the battle ended the same way. They returned again in another episode when Hao was close to getting the Great Spirit they fought Hao's followers and held them off  long enough for Yoh and the others to get to the Great Spirit.
