Antagonist turned unlikely ally Meg Masters made quite an impression on fans of Supernatural, but some things not everyone knows!

The hit show, Supernatural boasts countless strings of unpacked stories within the series' 15-year span. Characters come and go, with the most important ones dying in the end, but the shown is also known for finding a way to somehow bring a character back, whether it be a villain or a hero.

A famous demon that had been with the show from the first season and all the way to its last was Meg Masters. Initially, she was an enemy of the Winchesters, but later fluctuated in her role and eventually remained as an unlikely alliance or a frenemy for lack of a better word. Meg's character evolved drastically over the course of seasons 1 to 8 and ended up in a spot that wasn't ideal. Nevertheless, Meg's entire character was hard to underestimate.

10 She Was Attracted To An Angel

This whole affair hit viewers like a fallen angel crashing into Earth. It seemed sudden when Meg pulled Castiel in for a kiss, then when Cas returned the favor after watching "The Pizza Man," but their interesting relationship grew over time. Meg ultimately risked her life for Cas (and the brothers) against Crowley, but fans couldn't help but question who she really intended to risk it all for, whether it was for all of them or just for Cas.

Calling him Clarence after the angel from It's A Wonderful Life, Meg made it clear that she was holding a torch for the angel for quite some time, which definitely painted an unrequited love kind of thing for the two characters. However, since their relationship wasn't a huge focal point, the demon and angel's relationship didn't have enough screen time to fully defend what was going on between Meg and Castiel.

9 She Sacrificed Herself For The Winchesters

In the fight against the Leviathans, Meg was eventually captured by Drowley and his demons. While viewers still debate over whether or not she did, in fact, sacrifice herself purposely for all the boys or just for Castiel's sake, Meg still helped them and fought to the end defending them.

Meg endured some brutal beatings from Crowley and the demons from Hell, including being chained to a bathroom at a hotel she was taken to. The torture she went through was to push her to confess the whereabouts of the Winchesters, but the rebellious demon never specified, proving how tough she really was.

8 Her Vessel Became "The Shadow" Of The Empty

Towards the end of the entire series, fans saw Meg once again long after she was killed by Crowley, but not as herself. Poor Meg became the vessel for The Empty's shadow, otherwise known as simply, "The Shadow."

The Empty used this specific vessel to taunt Castiel since loyal fans kept in mind the ultimately toxic connection between Cas and The Empty. While Meg did not cause this upon herself, it was still jarring to see her as the chosen possession for the dark afterlife that The Empty is. Even Cas was at first happy to see Meg as he turned around to face her while in The Empty itself until he realized that it wasn't actually Meg.

7 She Adopted Her Name Based On The Original Human Vessel's Identity

This was when Meg had the darker side that the Winchesters initially experienced. She didn't only possess a human, she also took on that human girl's entire identity and reinvented it. The real Meg Masters that appeared as a ghost, later on, confessed how the demon Meg changed her wardrobe and cut off her hair, disapproving of the entire new look.

The demon Meg definitely didn't hesitate to acclimate herself on Earth and connect with others as a human being. This was a strong tactic in tricking Sam back in Season 1 before he and Dean found out she was a demon.

6 She Suffered From Hell's Torture

Meg swore revenge against the Winchesters, specifically, Dean, for exorcising and sending her back to Hell in the early seasons of the show. Once back in Hell, she endured a roughly similar experience to Dean as fans would always recall his debilitating and soul-crushing time in Hell.

Once she returned to Earth, Meg had no problem planning on taking Dean out slowly, just as she suffered. While a demon isn't expected to have real feelings over anything for that matter, Meg was a different case since she later had some feelings for Castiel. What Meg had gone through in Hell defined most of her actions in Season 2 when she had apparently escaped and then possessed Sam.

5 She Flirted With And Then Threatened Jo Harvelle

Although she was possessing Sam at the time, Meg still put on a pretty convincing performance in front of Jo. Meg attempted to hit it off with Jo as Sam, but anyone that watches the episode will see that Jo wasn't having it. Meg used Jo's trauma about her father (who hunted with John Winchester and later died because of him) to influence Jo in their conversation.

Knowing that Dean would eventually show up, Meg then knocked out and trapped Jo at the bar they were in, and proceeded to be like all the other demons that would use personal information against their victims. Meg used Jo as the bait she needed for when Dean would show up, which he did, to save her from "Sam's" apparent, uncontrollable killing spree.

4 Her Second Vessel Was An Aspiring Actress In Los Angeles

This was a random bit of information for viewers, but essential because it was when viewers understood where Meg found another vessel when she was exorcised out of the original human, Meg Masters. The only reason why she admitted this was because she was tied up and tortured by a possessed Christian Campbell.

This scene showed fans just how much of a serious backbone Meg had since she fought the pain back with sass and determination, even though she basically mocked her meat suit.

3 She Was Brought Back Into The Fight By Castiel

Referring to one of the many fights the Winchesters and Castiel went through, Meg left the boys when they were up against the angels and Dick Roman. She supposedly told Castiel that she enjoyed staying out of sight on her own.

Cas was the one to call her back however and bring her to the brothers, which appeared strange to them and viewers because they didn't necessarily need an assistant. Without her though, fans don't know what would have happened since she sacrificed herself for them, but mainly Castiel as fans figured out. When he brought her to Sam and Dean, Meg claimed that "her angel" had "zapped" her back when she was far away from them and the fight.

2 She Was Technically Abandoned By Castiel And The Brothers

Well, this was a bit of a heartbreaker, primarily to the whole Cas and Meg relationship story, but it was true. Sam, Dean, and Cas basically left Meg, since they didn't look for her after Crowley and his demons took her. Cas found out where she was and killed the demons that were guarding her.

Despite Castiel's heroism, and even his plea to Naomi to defend Meg, nothing could erase the fact that the boys didn't immediately help her when she was abducted. The pain Meg went through when Crowley and his henchmen demons beat her was already enough of a sacrifice. She didn't budge when they forced her to tell them where the Winchesters were, so it would have made sense for them to help her sooner than later. Sadly, they didn't, so it was a small surprise to see that she didn't hold this grudge as strongly as others would have.

1 She Was Officially Killed By An Angel Blade

Dying on Supernatural always meant there was still a way to live, and so when Meg was sent back to Hell in Season 1, it wasn't much of a shocker to see her return with a swinging vengeance in Season 2. However, her official death was when Crowley ruthlessly and quickly stabbed her in Season 8.

It was strange when Meg was killed because, in comparison to every other battle that she fought tooth and nail through, a blade ended her life quickly and easily. From all the torturous beatings and interrogations, and fights she was in against angels, demons, Leviathans, and monsters in general, it was hard to grasp the fact that she died with one motion, in a split second.
