The current version of Song Ji Hyo is tame and a bit of a ditz.
But there is a reason why they call her The Ace. Jihyo uses her beauty and wit to disarm her opponents, which is why it's hard to see her without a meat shield like Kang Gary at the start of the series, Haha as the Mapo brother, and Kim Jong Kook in more recent history.
She can also operate ruthlessly by herself. Now I don't want to be that guy who compares Song Ji Hyo and Jeon So Min but yeah, So Min is more of a female version of Lee Kwang Soo while Ji Hyo can be a commander (or a sudden commander) if she wants.
So check out this old Running Man episode to check out her old school version.
