Moltor is a lava monster and an enemy of the Nexo Knights. He was summoned by Jestro and the Book of Monsters.
Moltor's head, legs, and torso are black with cracked lava rock patterns. His face has a wide grin. He has brown shoulder armor with orange spikes, and reddish brown hands representing his boulder fists.
Description Hard-Hitter Weapon Boulder fists Skills Slamming things with his fists Dislikes Cold, snow and discussions Likes Heat and his brother Flama
To say that Moltor is a hard-hitter would be an understatement. This guy has boulders for fists, which gives him a quite devastating punch. Moltor is not big on discussions and likes to let his hands do the talking. He is usually seen creating chaos somewhere near his twin brother Flama. Together they are the Hot’n’Heavy twins that deliver a 2-for-1 offer on destruction.
His name is a pun on "molten", a word to describe minerals that have been turned into a liquid from extreme heat.
In the lava smasher set, his fists and shoulder armor are brown. In the TV series, however, the fists and shoulder armor are red, and his head is topped with a crag, which is not part of the original minifigure.
