Up for a different title, it's a decent one but doesn't fully explain the trope.
A team is gathered together specifically with members from different cultures and nations. The reasons may vary. It could be to gather together a team with a wide variety of skills to assist in the mission, it could be because the team is funded by an international organization or maybe it is a problem greater than one group and each nation needs to be represented to combat the conflict.
Compare the Five-Token Band
, but this is different as each member may not really "represent" their people so much as marketing trying to include everyone.
- Trope Namer comes from Lord of the Rings where The Fellowship of the Ring is a small band of heroes who are tasked with taking the One Ring to Mordor. The members include Frodo, Sam, Merry and Pippin representing the Hobbits, Aragorn representing humanity in general while Boromir represents the human nation of Gondor, Gimli representing the Dwarves and Legolas representing the Elves. This was significant as each group had a vested interest in the coming quest.
- Mass Effect takes pains to include as many alien species in your group as possible, as this does wonders for encouraging you to talk with them and understand their people. In the first game you have two human crewmembers besides yourself (Kaiden and Ashley) and you recruit a Turian (Garrus), a Krogan (Wrex), an Asari (Liara) and a Quarian (Tali). In the second game in the expanded DLC crew you can have four humans (Miranda, Jacob, Jack, Kasumi and Zaeed), a Turian (Garrus), a Krogan (Grunt), an Asari (Samara), a Quarian (Tali), a Salarian (Mordin), a Drell (Thane) and even a Geth (Legion).
- Avatar: The Last Airbender established early on that they needed to follow the pattern of Aang learning how to bend water, then earth, then fire. For each element the group acquired someone to instruct Aang on how to bend those elements. By the end of the series their group was a mixture of all the different nations: Aang represented the long gone Air Nomads, Katara and Sokka the Water Tribes, Toph and Suki the Earth Kingdom and Zuko the Fire Nation.
- The order of the White Lotus also factored into this as it was an international organization, in the finale we see Iroh, Piandao and Jeong Jeong from the Fire Nation, King Bumi from the Earth Kingdom and Pakku from the Water Tribes.
- Captain Planet is often teased for the "market appeal" of including one member of every race in the group, but in practice the team members were all representatives of their people and thereby what can be accomplished when we work together. Straight from the opening titles "Kwame, from Africa, with the power of Earth... From North America, Wheeler, with the power of Fire... From Eastern Europe, Linka, with the power of Wind. From Asia, Gi, with the power of Water... and from South America, Ma-Ti with the power of Heart."
