Kenny Cavanaugh is the main antagonist in the Smallville comic book story "Paterfamilias".
Biography
Early life
In 1989, a boy named Kenny Cavanaugh was hunting in the woods with his father. They found a good watering hole and decided to split up to watch for deer.
Kenny pointed out the importance of camouflage to his father, putting a stick in his hat. As soon as they are in place, deer stampede, and to Kenny's horror, a giant meteor lands on his father. Kenny's disappearance became an urban myth in Smallville.
Paterfamilias
In the fall of 2002, Jonathan Kent took his son Clark and Pete camping in the same woods where Kenny disappeared. They thank him, and he heads back to the truck. Seemingly from nowhere, Jonathan was hit with a piece of tree and knocked out.
Jonathan awakens in an underground cave with other people that have been in this cage he's in for nine months.
There are several dead people. A voice introduces itself as Kenny, telling Jonathan that he's a good dad, and that his father, Kenny's, is gone. Kenny asks Jonathan to be his new father. Jonathan figures out who Kenny is, and what happened.
He starts trying to tell Kenny to take him to the cabin his father built, in the woods, when Clark and Pete arrived. Kenny sneaked out and attacks.
Clark caught him and threw him high into the air. Back at the cell, Clark broke the lock with his hand and the others stare in awe. At the truck, they hop in and speed off unaware that Kenny is underneath the grill, invisible.
At the Kent Farm, Lex tells the Kents that he has a security team on the way. They haven't found Kenny, however.
Jonathan went to the feed store, only to be met by Kenny, who told Jonathan to come with him or Martha will be hurt. Kenny and Jonathan drove through town where Clark and Lana noticed them.
Clark saw Kenny pointing a shotgun at Jonathan, and leaps onto the truck. Inside, Kenny hits the accelerator. Clark flies off into a kitschy souvenir shop sign, which explodes.
Clark walked out of the fire unfazed and asked a man if he could use his phone. He called Chloe who has information on Kenny pointing out the cabin Jonathan talked about with Kenny and Clark takes off.
At the bridge leading to the property, Clark and Jonathan tell Kenny that Clark would feel as distraught as he did if they took Jonathan away.
The bridge breaks, and Clark runs down, leaps up, and catches the two of them, telling Kenny it will be all right. At home, Lex assures the Kents that Kenny will receive the best care possible. After leaving, he calls the asylum to make sure that the cameras are in place watching Kenny.
