Fred's mother had given birth in the secret lab she worked at.
HE WAS BORN A MUTANT!!!
A new superhero was born today. We have to get rid of him!
A group of 3; Boil boy, Heat Wave, and Tempesta found out about Fred.
The trio captured Fred Mercury and brought him to their lair.
Fred outsmarted Tempesta and brought boil boy into the room. Hear Wave's body heat heated the room to Mercury's melting point, 234.28 K, to keep him at his normal state.
Tempesta uses her powers, using freezing point to turn the room 234.32 K to turn Fred into a solid block of mercury.
Boil Boy took Fred Mercury into another room and used his powers to heat up the room. He heated the room to 630.05 K to Mercury's boiling point to melt him to his liquid state. Mercury outsmarted them again and brought Tempesta into the room.
He used Tempestas powers to turn the room back to his normal state at 345.15 K. The trio realized they couldn't take Fred down as individuals. They came into one room to take him down.
Boil Boy and Heat wave worked together to heat Mercury to 638.75 K to vaporize him into a gas. Mercury knew how to trigger Tempesta's powers and cool the room down to where he can condensate back into his liquid state, then cool it down enough to solidify to 234.32 K
They couldn't get rid of Gred Mercury and gave up. Fred told them he was going sublimate all three of them and turn them from solid humans to a gas. He told them that he would use his power to increase kinetic energy within them and they would turn into a gas. Mercury actually has no powers and is just smart. He laughed this off and put them in jail.
