These aren't your little sibling's Lego creations.

YouTube user Counter656 created a stop-motion video that pits Lego ninjas against each other in a fierce fight. Posted online earlier this week, the video highlights the metallic clang of swords clashing and the sound of lightning-fast footsteps of warriors in pursuit.

The battle eventually kicks into high gear, when the ninjas throw fire balls and spin tornadoes.

And with no clear winner, there's definitely the potential for a rematch.
