1) HANK SCHRADER FROM BREAKING BAD (DEAN NORRIS)
Sure, BREAKING BAD was about a lot of things, ranging from Walter White's relationship with his wife, or the edgy bond with Meth-making partner Jessie, but keeping the truth from his DEA brother-in-law Hank was always the bottom line... And it was Hank who could end the party, right quick, if and when he discovered the truth... And he was always searching to expose his man: to close the curtain for good...
2) CLIFF BARNES FROM DALLAS (KEN KERCHEVAL)
Born into squalor and jealousy, Cliff Barnes did all he can to overthrow the evil and awesome JR Ewing, and to put Ewing Oil into the garbage, which then would make DALLAS... all about JR screwing people around... be no more.
3) JACK McGEE FROM THE INCREDIBLE HULK (JACK COLVIN)
"You wouldn't like me when I'm angry," David Banner tells snoopy yellow journalist Jack McGee, who dogs Banner's tail for the entire five season series, to expose the THE INCREDIBLE HULK and uncover the green giant's true identity, which would destroy the cross country trek.
4) EUGENE FROM THE WALKING DEAD (JOSH McDERMITT)
Eugene, the passive guy with the mullet, is more neurotic than intrepid yet he might just hold the key to save the human race, ridding the world of zombies, or rather, walkers... which would be great for the characters but bad for the rabid WALKING DEAD fanbase.
