Radim

Radim is the Patch Officiant who is selected to be the commenter of the tournament.

Personality
Unlike most of the other officiants, he tries his best to remain neutral, but at times has openly agreed that he doesn't approve of Hao's shaman only kingdom (going so far as to get Hao's furyoku rating during the fight with X-III). He is constantly making ridiculous comments and announcments during the fights, and mostly act like a coward when the larger OverSouls appears, such as with the Yamata No Orochi Go, or crying that he was afraid of needles when seeing Mephisto E. However when Yoh and his friends met him in the Plant of the Lake, he showed a more serious side(possibly because of the effect of the Patch Song) and even said that it was said that he had to fight them. But he still attacked them because of his sence of duty. Even though he is still not a cruel person and even offered them to go home.

Spirit

 * See More: Platinum Sword

His spirit is an Australian pelican named Platinum Sword, with his medium being his microphone. When oversouling Platinum Sword into the microphone it creates a sword of concentrated furyoku.

Shaman Fight 2nd Round
Radim is a member the Patch Tribe and one of the Ten Officiants. He is responsible for commenting the fights and made his official appearance in the opening fight of the second round of the Shaman Fight where he announced the rules of the fights and explained the conditions. He is then seen in every official fight during the second round of the tournament. During this time his comments works as a constant running gag.

He is later seen at the Patch`s "Patchmarine" a Submarine OverSoul, drinking something hot, while complaining about the surrounded island, saying that it would be impossible to transport the last contenstent to the island of Mu without beeing noticed.

VS Radim. Plant of the Lake
After having defeated Magma, Yoh and his friends enter the Plant of the Lake where they encounter Radim, standing in the middle of the lake. Announcing that it is to sad that acquaintances much fight each other, he also announces that he is a part of the Patch and a job is always a job. He then reveals his spirit and his OverSoul.

Anime/Manga Difference
Because of the large anime/manga difference with the second round of the Shaman Fight, Radim never makes an official appearance in the anime. Instead are the fights supervised by various Patch Officiants who are also judging them.
