In the fifth episode of MBN's variety program 'Legendary Men,' the TOP7 members and their families competed in a fierce battle of pride. In particular, the thrilling head-to-head match between Seongri and Jo Kwon for the title of 'Performer Ace' captured viewers' attention.

During an impromptu dance battle to determine the 'Performer Ace,' Seongri dominated the stage with an idol-style choreography to 'Growl.' Meanwhile, Jo Kwon, true to his nickname 'Kkap-Kwon,' performed Girls' Generation's 'GEE' with an energetic and animated performance. Their stages drew explosive reactions from the audience, with comments such as 'It feels like watching real celebrities' and 'Their energy is on another level.'

The families' performances also stood out. MC Yang Se-hyung invited Jeong Yeon-ho's father and Kim Tae-woong's mother, who had been highly active in the previous first round of the 'Family Pure Love Battle.' The two captivated the audience with excellent stage presence and vocal skills. MC Jang Min-ho praised them, saying, 'It feels like we have two guest singers today,' and the TOP7 members also cheered enthusiastically, declaring, 'We'll become their number one fans.'

Next, Seongri and his older brother, along with Lee Chang-min and Jo Kwon, each formed teams to put on duet stages. Seongri's brother displayed special brotherly affection, saying, 'I've been benefiting a lot from my younger brother lately,' and their mother in the audience could not hide her proud smile. Watching this, Jang Min-ho marveled, 'Their voices are so similar that it sounds like Seongri keeps talking.'

Taking the stage, Jo Kwon showcased his signature wit, saying, 'I'm Kkap-Kwon Jo Kwon. I came out to shake my hips for the first time in a while.' During this segment, when Jang Min-ho asked Lee Chang-min about his solo activities in relation to 2AM's possible disbandment, Jo Kwon answered honestly, 'To be honest, it does feel unfamiliar.'

Meanwhile, in the 'Unknown Legend' corner, Cho Seong-hwan, who has been generating buzz, participated in a 'Father-Son Battle' with his high school senior son, drawing attention. Cho Seong-hwan displayed strong confidence, calling himself 'the best rookie singer produced by Unknown Legend.' The MCs also introduced that a video of Cho Seong-hwan singing Lee Mi-ja's 'I Loved You' had surpassed one million views. When Yang Se-hyung asked Cho Seong-hwan's son, 'Between your dad and mom, who sings better?' the son's witty answer turned the studio into a sea of laughter.

The honor of ultimately claiming the 'Performer Ace' title and the final winner of the 'Family Pure Love Battle' were revealed through the broadcast airing at 9:40 PM that night.
