Well, the entrance of YC1 is
1. Benn Beckman : Pointing a gun to kizaru, but kizaru did attack the submarine anyway.
2. Marco : Defending Whitebeard from Kizaru's Yasakani No Magatama with his phoenix DF
3. King : Kicked Queen Mama Chanter off from waterfall in Wano.
4. Katakuri : Killed one fodder in front of Wedding Plaza in Whole Cake Island
5. Shiryu (Before timeskip) : Killing impel down fodder after being released.
Shiryu (After timeskip) : Ate Invisible fruit.
From that entrance, seems like oda will not disrespect King's power. We dont even know how his sword fighting ability.
