|"That's not what happened at all!"
The Thunder Keepers are members of the Keepers.
Behind this fearsome mask is an equally forbidding islander! He isn't in a bad mood though-he just takes his job seriously. Using ancient chants and rituals, the Thunder Keepers call out to the storms that surround the island and asks them to never stop scaring off unwanted visitors!
Singing, dancing and painting creepy masks - that's all these guys do! They do this because they believe it will create violent storms that keep the island hidden it appears they didn't sing loudly enough...
- LEGO Brawls (non-canon)
- They are the only Keepers not to appear in the show.
- Ironically, they are the most common Keeper minifigure in the sets.
- Their masks are inspired by the Island Warrior's mask from LEGO Minifigures, but the Thunder Keepers' masks are attached to the head, unlike the previous mask, which is between the head and the body and its wearer also has hair. The Thunder Keepers' masks also lack eye cutouts.
- This is pointed out in a Thunder Keeper's description in Hunted!, which states that "masks restrict visibility - good for the ninja, not for the mask wearers!"
- According to Keeper tradition, the Rumble Keepers can participate in a ritual challenge and become Thunder Keepers if they prove themselves worthy in the challenge.
