backpack kid

The legendary "Backpack Kid" dances with Katy Perry. He has no soul and moves like a robot, but he's actually an alien who comes from Proxima Centauri. He has the longest arm on the world and has the "Paty" Backpack, who gives him superpower. This backpack was made by the dance god "Shun Fik" in the Lear 1578.

We usually don't say the name of this living god because it could hypnotise you and make you dance so long until you die.
