ThunderCats Roar (2020)

S01E17 Berserkers

The Cats' Lair comes under siege by gold-obsessed robot pirates known as the Berserkers. Surprisingly, this turns out to be a positive twist, as it gives Lion-O and the ThunderKittens an excuse to abandon their chores and engage in battle with the robo-pirates. Just make sure Tygra doesn’t find out!
