Although it is not legitimately a Fairy Tail team, the Team Tenrou was created during the X784 S-Class Mage Promotion Trial. It is composed of Fairy Tail's core members, including Makarov, who oversees the entire trial, the existing S-class Mages who supervised the trial, and the participants with their partners, who first arrived on Tenrou Island, followed later on by Carla and Panther Lily who flew over to the island via Aera in order to warn the others of the danger about to befall on the place. Laxus Dreyar also arrived on the island to assist in the fight against Hades.
- Makarov Dreyar: As Fairy Tail's Master at the time, he acted as the Trials' supervisor, and is considered the leader of the team.
- S-Class Mages: While not directly participating in the Trials, it was the responsibility of Erza Scarlet, Mirajane Strauss, and Gildarts Clive as S-class Mages to help facilitate it, and were therefore a part of the team prior to its unofficial foundation.
- S-Class Trial Participants: As the main competitors in the Trials, Natsu Dragneel, Gray Fullbuster, Juvia Lockser, Elfman, Cana Alberona, Freed Justine, Levy McGarden and Mest Gryder essentially make up the primary members of the team. Mest, later revealed to be a member of the Magic Council and whose real name is Doranbolt, defected after his real identity was discovered.
- S-Class Trial Participants' Partners: For the S-Class Mage Promotional Trial, the participants had to choose one partner who was a member of the guild and wasn't already an S-Class Mage. Those partners were Happy, Loke, Lisanna, Evergreen, Lucy Heartfilia, Bickslow, Gajeel Redfox and Wendy Marvell respectively.
- Late Arrivals: Eventually, Panther Lily and Carla became a part of the team, after they followed the rest to the island because they had been suspecting Mest to be an enemy, and Laxus joined later on to help in the battles.
Defeat Grimoire Heart
While holding the S-Class Trial, the Dark Guild Grimoire Heart attacked Tenrou Island in order to find Zeref and create the Ultimate Magic World. The Team Tenrou, after a powerful struggle, managed to defeat its top members: the Seven Kin of Purgatory, Bluenote Stinger and Hades himself.
After defeating Grimoire Heart, Acnologia appeared on Tenrou Island, wreaking havoc. Makarov tried to stop the Dragon single-handedly to allow his Guild the time to escape. Rather than run away, however, they all returned to fight the Dragon together. In the end, Acnologia seemingly obliterated Tenrou Island with his Dragon's Roar.
- Status: Failure
- All members of the Team Tenrou are presumed deceased for approximately seven years.
