Souther could give him a decent fight for like 2 mins but Wei Phoenix will say that Kaioh wouldn't know about Souther's secret and lose.

Kaioh, the only reason Souther was a threat was because his pressure points are reversed, but pressure point attacks aren't the only thing Kaioh uses, in fact he relies more on other types of attacks like ki blasts and his aura.
