Meruem with the same effort against Netero vs 3 Royal Guards combined?

Who do you got?

Round 1:

Meruem is not out for kill against the 3 Guards, just beat their ass until they give up. Kind of like how he was with Netero.

Round 2:

If you think Round 1 that the RG's would win, then how about Meruem who is going all-out?

This is Pre-Rose btw
