At first glance, the city appears to function as a normal day. The exception? If one was to glance and squints really hard they might have notice a building in the sky. The building appears to be upside-down compared to the buildings on the ground. It looks like a luxuries condo building as the window reflects the sun's rays.

Inside the building, two mysterious figures emerge, a boy and a girl. A set of chess lays in front of them as they take their sit.

"Adam, have you decided on what you are betting?" the girl questions the boy as she sits down.

"Of course, Eve." Adam smiles at Eve. "It wouldn't be fun otherwise, if we had chosen the same thing."

"May the best Evolution win!" said Eve as she moves her first white piece forward.

Instantly, a message appeared on people's smart devices.

"Please choose one option:

A- Gain superpowers but keep the same body

B- Gain superpowers but gain a body transformation?"

Sudden confusion arise as people started reading the message. At first, they thought it was a prank. But it becomes more mysterious when the message could't be closed. Once the response was chosen, the message would disappear instantly.

Weeks went by and people was beginning to forget about that strange message.

Until the first incident happens.
