Fire Lion

With its all-terrain treads, quad-rocket pod and roaring engine, Laval’s Fire Lion is already a mighty force on the battlefields of CHIMA. But when things get really tough, Laval fires it up with Chi to transform it into a towering, treaded lion-mech that can smash and claw its way through any frozen obstacles – or Ice Tribe vehicles – that dare to stand in its way.

Trivia

 * Laval got the Fire Lion as a gift from his father.
 * Despite it being said that it's a common design, the Fire Lion never appeared before episode 28, leading to some canon confusion, but it does have a similar tread setup to the lion tank, so there is some truth in that statement.
