Nexo Knights is a fantasy-based Castle theme. Unlike it's predecessors that contained typical medieval elements, usually with a fantasy themes, Nexo Knights gives those elements a futuristic look combining both technological and magical aspects. Like some previous castle themes, it features two factions, the heroes being the Knights, and the villains being magical evil creatures. The sets features Nexo powers that can be used on the Nexo Knights app.

Vehicles and structures used by the Nexo Knights features silver and blue as the primary colors and using orange for windows and holograms. The designs of the vehicles are based on medieval weapons, in the case of the main heroes the vehicles are based on their signature weapons.

In the case of the lava army, they feature brown as they primary color scheme with transparent orange bricks for the lava. The designs of the vehicles have monstrous aspects with white fangs and horns, and it's weapons have lava desings.

The Ultimate sets includes one character with an exclusive design, and a set of accessories matching with the character’s faction, and includes three Nexo Powers. The sets are not used on a game unlike Ninjago’s Spinners or Chima’s Speedorz.

Later, the evil cloud Monstrox comes and turns Jestro evil again by zapping Jestro with a lightning bolt that can turn anyone evil (or bring stone statues alive). Jestro and Monstrox then team up to fight the Nexo Knights again, this time with a stone army instead of lava. The Nexo Knights are defeating Jestro, Monstrox and Runia.

NEXO Powers

Main Article: List of NEXO Powers


  • The characters' names play on words. Robin is a pun on "Robin Hood", Macy on "mace", Axl on "axe", Aaron on "arrow", Lance on "lance", Clay on "claymore", Moltor on "molten", Lavaria on "lava", Jestro on "jester", General Magmar on "magma", and Flama on "flame".
  • The emblems of most of the main knights are reminiscent of many Classic Castle themes. For example, Aaron reuses the Wolfpack sigil, Axl employs the Knights Kingdom I robbers' bull symbol, and Clay reuses the Black Falcons' emblem. Macy's dragon symbol may be an alternative take on the Dragon Knights symbol.
  • Two books and a TV series were released with the theme.
  • Unlike all of the other Castle-related themes, this theme is settled in a universe that is a fusion of the medieval with the technologically futuristic, which has displeased many traditional Castle fans.
  • A Knight cameos in the trailer introducing Clay.
  • This is the fourth theme to get its own full TV show (except Mixels, which only has shorts aired on TV).
  • Ninjago is referenced in the series when Lance's agent suggests that Lance audition for "Knightjago 3," where "the hero spins around to defeat his enemies and stuff."
  • Legends of Chima is referenced when the simulator room in the new Fortrex is revealed to the knights, and the Lion Temple is briefly simulated along with a few other locations.
  • The TV series was renewed for a second season in the same year it's introduced.
