Not every character can be a lead, but that doesn't mean every actor doesn't make every minute of their screen time count.
These characters have become fan favorites and seem to steal the scenes out from under the noses of their top billed coworkers. How do they do it? Skills and charisma, among other things.
Scroll through the photos and tell us if you agree -- they are scene stealers!
Emily Betts Rickard as Felicity on Arrow
Can you imagine Oliver Queen without Felicity? She's a figment of the TV show but fits so perfectly into the Arrow world that she's managed to outshine canon characters. That's a first rate scene burglar.
Nick Offerman as Ron Swanson in Parks & Recreation
Any man who can silence a room merely by mentioning meat or breakfast food is worth his weight in gold. It turns out Ron just so happens to have that much gold. Perfect.
Austin Basis at J.T. on Beauty and the Beast
When J.T. isn't in an episode, the show isn't as fun. He brings levity and comic relief to every situation. The light shines on his lines.
Gwendoline Christie as Brienne of Tarth on Game of Thrones
Her scenes have been few, but whether she's deftly defending the Kingslayer or fighting for her life against a grizzly bear, it's impossible to take your eyes off of Brienne.
Andrew Rannells as Elijah on Girls
Every time Hannah's gay ex Elijah pops up on Girls it's safe to say something wild will happen. Whether it's a coke-fueled club night or crashing a weekend at the beach, his fast talking wit helps him steal every scene he's in.
Kristin Bauer van Straten as Pam on True Blood
Pam simply commands attention. When she's on the screen it's impossible not to gaze at her. Our hope is this fan favorite gets her due in the show's final season
Jimmy Smits as Nero on Sons of Anarchy
He may not even be in SAMCRO, but the character's charisma and moral center cause him to stand out in any scene he shares with Jax. Will these two be adversaries on Season 7?
Jonathan del Arco as Dr. Morales on Major Crimes
It took him 5 seasons of The Closer and one on Major Crimes to become a series regular, but we've been a fan of his quips and quirky comments in the morgue all along.
Sarah Rafferty as Donna on Suits
If only every assistant was as revered as Donna. She's so important to the team that they allow her to bring down the bad guy to keep her happy. When Donna enters a scene, the game changes.
Norman Reedus as Daryl Dixon on The Walking Dead
Daryl is another entry written into a fictional world for TV that we couldn't live without. Nothing like his brother, his love for Lil' Asskicker and connection with the survivors won our hearts. If he goes, we go.
Mark Sheppard as Crowley on Supernatural
Crowley rules a room. He makes an entrance and his snark guarantees even an unpleasant visit will be a good time. His soft spot for the Brothers Winchester finalizes the sale.
Silas Weir Mitchell as Monroe on Grimm
Monroe has all of the personality on Grimm. He has the humor and the successful romance. He's more of a lead than Nick, but he's living on the wrong side of the fence. We don't care. He still steals every scene.
Uzo Aduba as "Crazy Eyes" on Orange is the New Black
Suzanne "Crazy Eyes" Warren surprised us by not being the one dimensional crackpot we expected, but showing deep and true emotions to her Dandelion. She's a scene stealer and a heart breaker.
Janel Parrish as Mona on Pretty Little Liars
Whether Mona's being crazy or cute, she draws attention. That she's managed to blend in as a member of the A team proves how great of an actress Mona is, because otherwise it's impossible to take your eyes off of her.
Jordan Gavaris as Felix on Orphan Black
Sure, the show is about clones and Tatiana Maslany gets the accolades for playing them, but who has to play against them? Felix gets all the best lines and Gavaris' job of treating each clone differently in various scenes hits the mark perfectly.
Gabriel Mann as Nolan Ross on Revenge
Nolan's crazy clothes, unending devotion to Ems and willingness to try just about anything for his friends makes his every move utterly delightful.
