Gran decides to host trials meant to decide who among the Thunder Sisters will become the next Thunder Queen.
Tropes for this episode include:
- Game Between Heirs: The Thunder Games are a series of trials that Thunder Sisters undergo to decide who becomes the next Thunder Queen.
- Running Gag:
- Thunk coming up with a Thunder Sister nickname for himself, only for Gran to insist that his name is still "Thunk".
- Gran dreamily remarking that each of the dangerous trials of the Thunder Games was "the greatest moment of [her] life."
- She Is the King: Since he's a Thunder Sister, Thunk is allowed to compete for the title of Thunder Queen despite being a man—err boy, not that Gran has any confidence that he could beat the others.
- Vicariously Ambitious: Hope finds the role of Thunder Queen to not be worth it, but she wants Dawn to be Thunder Queen instead.
