Epic Battle Set - Kai vs. Skulkin

The LEGO® Epic Battle Set - Kai vs. Skulkin (set 71730) is a 70-piece LEGO Ninjago set released in 2021, staging a classic good-versus-evil duel between fire ninja Kai and his bony skeletal nemesis from Seasons 1 and 2 of the NINJAGO TV series. The set includes a small brick-built temple as the duel's stage, a spinning battle platform Kai uses to whirl into action and knock down his opponent, and four red weapons for extended combat options. Two minifigures ship with the playset: a new-for-January-2021 Kai variant and a Legacy Skulkin warrior. A compact, action-focused entry built around dynamic spin-versus-strike battle mechanics.
