Here are the biggest villains from previous seasons of "The Bachelorette."

Chad Johnson, Season 12We're only in Week 2 of the current season, but Chad has already established himself as the villain. He's aggressive, doesn't care about the other men in the house, and in last week's episode, he called JoJo "naggy." He also ended a toast with, "F--- you guys, I’m gonna make her my wife.” Classy.

JJ Lane, Season 11Well, for starters, he coined the phrase, "villains gotta vill" with Clint Arlis. He became the most hated man in the house when he stole Kaitlyn Bristowe away from the other men, although he had already secured a rose. Then, there's this lovely quote: "More than anything I’m feeling just smugness wrapped inside of cockiness wrapped inside of confidence wrapped inside ‘I just talked to the girl and you didn’t.'" That's the dating version of a Thanksgiving turducken.

Ian Thompson, Season 11Thompson famously blasted Kaitlyn Bristowe for being "shallow," when he was clearly so full of himself. He left the show by saying, "I need to have sex." Good luck with that.

Kalon McMahon, Season 8He called Emily Maynard's daughter "baggage." The moment wasn't caught on camera, but other contestants let Maynard know and McMahon was promptly sent home. He is not winning the Stepdad of the Year Award.

Justin Rego, Season 7This guy also had a girlfriend back home when he tried to fight for Ali Fedotowsky's heart, but he literally ran away when she tried to confront him about it.

Joe Bailey, Season 11He didn't really spark controversy during his time on "The Bachelorette," but what he pulled on "Bachelor in Paradise" is worth mentioning. He famously dumped single-mom Juelia Kinney to stay in the competition for Samantha Steffen, with whom he had talked to before the show and told her he would do anything to stay until she arrived.

Juan Pablo Galavis, Season 9Galavis was considered the hottie of Desiree Hartsock's season and didn't make bad headlines until he became the "The Bachelor." He stunned the world during his overnight date with Andi Dorfman, where she accused him of only talking about himself, not wanting to learn more about her, and boasting about his overnight date with Clare Crawley. And she told him she would "die" if she heard him say "it's OK" one more time.

Ben Scott, Season 9Ben started his war against other contestants vying for the heart of Desiree Hartsock during the premiere when he brought his son to the cocktail party. Then, he would often swoop in on other people's one-on-one time. After he was eliminated, his true colors came out when he asked the producers on camera when he could be seen out with other women.

Wes Hayden, Season 5This guy was famous for saying he was the "first guy on 'The Bachelorette' to ever make it to the Top 4 with a girlfriend.” Indeed, he was accused of only coming onto the show to promote his music while his girlfriend stayed at home. 

Dave Good, Season 5He didn't have a girlfriend at home and didn't diss Jillian Harris, but instead he drank a lot and became increasingly aggressive, especially towards fellow contestant Juan Barbieri.

Nick Viall, Season 11After he blasted Andi Dorfman during "After the Final Rose" for sleeping with him (that's just not something you talk about), he begged to come onto Kaitlyn Bristowe's season midway through, much to the anger of other contestants.
