We have seen the Mane Six used their Rainbow Power to defeat Lord Tirek and save Equestria. But now that Twilight Sparkle has been captured and turned into Twivine thanks to Omega Brony, a new team has been formed. They are known as the Key Six.
DISCORD (Key of Magic)
He is the reformed bringer of chaos and their leader. He gave Scorpan's Medallion to Twilight in order for her and her friends to unlock the chest and use their Rainbow Power to defeat Tirek.
COCO POMMEL (Key of Generosity)
She is Suri's assistant for the fashion show in Manehattan. She was so generous that she gave Rarity a rainbow thread. She will face her fears as Twivine attacks with her plunder vines.
SPITFIRE (Key of Loyalty)
Leader of the Wonderbolts. She was gonna have Rainbow Dash for Team Cloudsdale, but she has shown great loyalty that she wants to join Team Ponyville. Spitfire gave Dashie a wonderbolt badge.
CHEESE SANDWICH (Key of Laughter)
The Powerhouse of the Key Six, and a Party Planner. Him and Pinkie Pie had thrown a party for Rainbow Dash and after that was done, he gave Pinkie his rubber chicken called Boneless and kept Boneless 2.
SEA BREEZE (Key of Kindness)
Sea Breeze may be small, but with the power of the breeze, he can fly at maximum speeds. He gave Fluttershy the flower for her kind intentions towards the breezies.
SILVER SHILL (Key of Honesty)
He was the helper of the Flim Flam Bros. Miracle Curative Tonic, but Applejack was honest that it was a fake. Silver Shill gave her a bit.
Together, they will defeat Omega Brony and free Twilight Sparkle from her plunderseeds curse and save the Tree of Harmony.
