A simple cat he was, but he was always smarter then his siblings, not to a human level but still more intelligent than other animals, until something changed.

[Scene shift]

a piece of Kryptonite is seen falling from the sky and falls in between an alley with a cat in it, the cat called whiskers is seen laying on top of cardboard boxes, yawning from boredom.

Suddenly the Kryptonite falls into whiskers mouth and whiskers swallows it accidentally, whiskers, thinking it was a small rodent that tasted funny, didn't think much about it.

So whiskers stood up and walked into a cat sized hole in the sewers and layed on a nest of random small soft things, closed his eyes and slept.

Unbeknownst to whiskers, changes were happening to his body and his fur turned slightly green from his usual black and white, his claws started to shed and green glowing claws formed.

As the Kryptonite started to fully assimilate in whiskers body it dissolves and started to run threw his blood into his heart and brain, making him Superhuman intelligent.

As whiskers body slowly gets used to the changes, somewhere in the metropolis, someone is planning something.

"So, the radar picked up something with the same radiation level of Kryptonite." Lex Luthor said as he took a sip of expensive wine while looking out of the window.

"Yes, the radar picked it up and it says the Kryptonite landed in metropolis." Mercury said as she holds file.

"Send a team to the location to get the Kryptonite." Luthor said as he smirked, he took another sip of wine as he looked down from the skyscraper.

In the base of the justice Leagues, a meeting is happening with all the members present, "So bats, what did you call a meeting for?" The flash said as he looks at Batman.

"A high amount of radiation comparable to Kryptonite was found falling to metropolis, I have a suspicion that a small piece of Kryptonite landed in metropolis." Batman looked around the table and pulled up a holographic map, the map was then zoomed into metropolis.

A red pulse then spreaded through the mapped city trying to locate the Kryptonite, the holographic map then zoomed into an alley way where the Kryptonite landed.

"The radiation is coming from an alley way." Batman said.
