Team Ren is a manga exclusive team in the Shaman King franchise.
Before heading into the first tournament event in Tokyo, Ren forms this team in Patch Village with Horohoro and Chocolove. At first, Ren asks Ryu and Horohoro if they want to join his team. When Ryu states that he only join if Lyserg is there, Ren decides to recruit Horohoro and Chocolove.
Their team fight in the first match in the Shaman tournament in Tokyo against Tsuchi Gumi: Peyote and BoZ. With Chocolove's Over Soul disabling Peyote's ghosts with laughter, Ren defeats Peyote.
After their first match, they spectate the second match of Team X-I and join Yoh's team at the cafeteria. When Yoh makes a comment about defeating everyone with one strike, Team Ice Men gets agitated and demonstrates their power on Chocolove.
