How would Hisoka react if he sensed Meruem's power?

Do you think he'd be excited and try to switch hands, or would he be scared and turn tail?

I find this interesting to speculate because we know that Hisoka is always keen on challenging himself against strong opponents and finds enjoyment in that... but Meruem is so strong that he didn't only flabbergast the two other royal guards but made Knuckle withdraw from the plan of facing him head to head. Knov aged a lot only from witnessing Pitou's nen.

 

[Captain Cadaver]

He'd most likely be excited to meet someone so strong and dangerous, but very aware of the danger. Hisoka has shown himself to be more than someone with a one-track mind with things like him not desiring to fight Illumi or holding enough ill feelings towards his near death against Chrollo to go after the Troupe, so the risk of approaching Meruem wouldn't be lost on him.

 

[Symbiote]

He would get a major chub but also resist his urges.

 

[Pocket-Gog~]

He would kneel instantly to the king.
