Bachelor Nation's biggest villains

See the biggest villains from years of The Bachelor and The Bachelorette, ahead.

Krystal got off to a good start on the 22nd season of The Bachelor, but her early advantage went to her head. She quickly made enemies among the other ladies with her condescending attitude, annoyed Arie with an attention-seeking tantrum after a bowling group date, and eventually got sent home on the dreaded two-on-one.

Courtney Robertson achieved a rare villainous victory in the 16th season of The Bachelor. Despite alienating all of her fellow contestants and pushing the boundaries of network television, the model won winemaker Ben Flajnik's heart, accepting an engagement ring from the Bachelor, only to split with him months later.

Kelsey Poe found herself in less than favorable light in the 19th season of The Bachelor. She feuded with the other women, spoke about her "story" in a way that some took issue with, and finally found herself abandoned on an island with her nemesis, Ashley I.

Juan Pablo Galavis may have charmed as a contestant on Desiree's ninth season of The Bachelorette, but he soon showed his true colors as the star of the 18th season of The Bachelor. The former soccer star was crass, harsh with his romantic hopefuls, and even made an enemy out of Chris Harrison.

Chad Johnson joined The Bachelorette's 12th season and he was definitely not there to make friends. The cold cuts-loving suitor quickly crashed and burned as he managed to call Jojo a nag, threaten violence against his fellow competitors, and punch some walls all in his first few episodes.

Rozlyn Papa found herself in hot water with Bachelor Nation during the 14th season of The Bachelor. Though she was there to vie for Jake Pavelka's heart, Papa was kicked off the show when questions were raised about her relationship with a producer.

Justin Rego was rated R in the sixth season of The Bachelorette. Ali Fedotowsky kicked him off the show when she learned that he still had a girlfriend at home.

Tierra Licausi had trouble seeing eye-to-eye with the other women in the house from the first day of the 17th season. She continually fought with her fellow competitors and was labeled as a common enemy for the women hoping to win Sean Lowe's heart.

Kalon McMahon may have joined the eighth season of The Bachelorette in an attempt to win over Emily Maynard, but he spent most of his time fighting with the other men and referring to Emily's daughter as "baggage."

Michelle Money perfected the art of being a Bachelor villain. The hair stylist attempted to win over Brad Womack on his second run as the Bachelor, and made a name for herself with her intense confessional interviews, feuds with the other women, and aggressive interactions with Brad.

Ashley Hebert fell hard for Bentley Williams in the seventh season of The Bachelorette, but he didn't quite reciprocate her feelings. Instead, the businessman took himself out of the competition entirely, leaving the Bachelorette in tears.

Olivia Caridi rose to fame on the 20th season of The Bachelor thanks to her open-mouthed facial expressions, blind confidence, and inability to get along with the other women.
