It looks like the reason Sunggyu is INFINITE's leader isn't just because of his age.

The INFINITE members were the featured guests on a recent episode of KBS 2TV's 'Mamma Mia'. On the program, they were asked, "Have you guys ever fought each other before?". Sunggyu admitted, "We've fought hard about 10 times."

When asked who was a good fighter, he picked Hoya and said, "This kid is pretty good at fighting", and then pointed to Sungjong and said, "This kid kind of sucks at fighting".

Sunggyu then said, "Woohyun and Sungyeol fought once, but Woohyun won. I fought once with Woohyun, and I won", ranking himself as the King of Fighting in INFINITE.

He also added, "You win when one person loses their fighting spirit, or when we just don't want to fight anymore".
