Omnitrix

tu is walking around in the forest alone... the normal pathway to their house was blocked by some construction work, which was, to say the least, was annoying as all hell.

Suddenly, some sort of shooting star soars across the sky in re-entry and tu notices. They were amazed by the sight, but all of a sudden, the falling star changed its path towards them, and they had to run before it landed.

It crash lands, launching debris and tu to the side. They get up and look down at the newly formed crater at the edge. The spherical object rapidly cools down and the small ledge breaks away, making tu tumble inside.

Not long afterwards, the pod opens up, containing... a mysterious watch.
