1. The Eternal Captain Park Ji Sung
We also can't forget the iconic name tag ripping battle between Park Ji Sung, Kim Jong Kook, and Yoo Jae Suk, a showdown that left Running Man fans in awe.


2. Grasshopper Hunter Choi Min Soo
The haunting memory of Choi Min Soo has stuck with Yoo Jae Suk. During his first appearance on Running Man, the actor was betrayed not once, but twice by Yoo Jae Suk, prompting him to request the PD to create an extra episode for revenge. Episode 69 remains a particularly sweaty and intense one for the nation's MC as he ran tirelessly throughout the challenge.


3. Lee Kwang Soo
The episode aired on June 13, 2021, marked Lee Kwang Soo’s final appearance on the show, ending with an emotional farewell. In this episode, the actor read a letter to his fellow team members, repeatedly apologizing for his sudden departure due to health issues.


4. Lee Jun Ki
The newly emerging entertainment icon made a lasting impression on Running Man fans with his incredibly deep and humorous acting. Even though it was his first time on the show, he quickly earned the nickname 'the master of deep acting' among fans. His performance left such a mark that viewers immediately praised his talent after the episode aired.


5. Lee Jong Suk
From the moment Lee Jong Suk joined Running Man, he was paired with Song Ji Hyo for a secret dating mission. Quick-witted and clever, he consistently devised crafty plans to outsmart the Running Man members. During his time on the show, Lee Jong Suk showcased his playful and humorous side, delivering intense and competitive moments that entertained the audience. The actor, known for his charming good looks, appeared in episode 181 as a transfer student and won over not just Kwangja, Kwang Soo’s female disguise, but also many female students at the school. He also made a memorable appearance with his friend Kim Woo Bin in episode 138, where their close actions on the show made viewers envious of the strong friendship between these two heartthrobs.


6. Park Tae Hwan
Park Tae Hwan is a renowned South Korean swimmer, famous for winning an Olympic gold medal and being a world champion. He has earned four Olympic medals, five world titles, and 20 Asian Games medals. His muscular physique made him a formidable rival to Kim Jong Kook.
Park Tae Hwan appeared on Running Man in episodes 109 and 110. The teams were divided into three groups: Red Team: Son Yeon Jae, Yoo Jae Suk, Lee Kwang Soo; Blue Team: Song Ji Hyo, Ji Suk Jin, Ha Ha; and Green Team: Park Tae Hwan, Kim Jong Kook, Gary. In the final mission, the teams had to tear name tags to locate a bottle of medicine, which could either benefit or hinder them in completing the task.

7. Lee Dong Wook
Lee Dong Wook made multiple appearances on Running Man, including a special episode filmed in Vietnam. One of his standout traits is his relentless determination to achieve his goals, even when facing fierce competition like Kim Jong Kook. His charming masculinity and sense of humor won the hearts of many viewers.
In episode 179, Song Ji Hyo was thrilled to find her dear friend Lee Dong Wook while looking for her partner. They worked together seamlessly, and their sweet, affectionate moments made fans wish they were an item in real life.

8. 'Villainess' Lee Yoo Ri
The actress from 'The Fire of Revenge' brought endless laughter to the audience in episode 213. With her stunning and alluring appearance, Yoo Ri kept both the viewers and Running Man members constantly surprised.
She spent hours getting ready, including wearing height-boosting insoles inside her boots, which drove HaHa 'crazy.' However, once the game began, the actress showed no mercy, displaying her fierce fighting spirit. Lee Yoo Ri even threw caution to the wind, ignoring her previous dignified image by jumping through a large puddle, causing the whole crew to laugh in astonishment.

9. Lee Hyori
If Lee Yoo Ri is the 'villainess' of the screen, Lee Hyori is the 'national fairy' who dominates reality shows. Lee Hyori was the first guest on Running Man, making her debut in episode 1 to support the new show. As a former member of Family Outing, her appearance immediately took control, especially over the powerful Kim Jong Kook.
Our 'national fairy' was also a trailblazer for the 'dirty play' style that Running Man is known for, even grabbing actress Hwang Jung Eum's hair, leaving the other members in shock.


10. Kim Won Bin
The incredibly talented actor Kim Won Bin is known as Kwang Soo's most successful 'apprentice.' After initially being teased as weak during his first two appearances, he got his revenge in episode 225 by secretly eliminating all the members' name tags, even surprising his 'master' Lee Kwang Soo. It can be said that Won Bin is one of the few male guests to have both laughed and cried on Running Man.
The handsome Kim Woo Bin appeared on Running Man in episodes 166, 188, 189, 191, 225, and 240. In his episodes alongside his close friend and the show's comedian, Kwang Soo, Kim Woo Bin shed his cool image to deliver a hilariously over-the-top performance with Kwang Soo.
