Curse of Ratilla is the twentieth episode of ThunderCats 2011 TV series.
Lion-O defeats Ratar-O and frees the cats and asks them to hide in the underground near the ruins of Thundera.
Tygra and Cheetara find the Sword of Plun-Darr and suggest that the sword should be hidden in the Tower of Omens before Mumm-Ra finds the sword is unearthed. Panthro informs them that it is too late, pointing towards the approaching Lizard Army.
- Ratar-O: (While attacking Lion-O.) Not much of a king, are you? I pulled my people out from underground, built this mine, enslaved your pathetic kind, and will soon rule over all I survey. And you?
- Lion-O: I'm just getting started. (fights back) You're a tyrant who rules by fear. Your people are just slaves on the other side of the whip.
- Ratar-O: But my people are still standing.
- This is the third episode in the series to begin with a recap of the previous episode, "The Pit."
