Id pick Meruem King of the Chimera Ants to be the one who trains me!@VinMcCarthy
He insanely strong and fast. Im sure he's the strongest in all of Hunter x Hunter and that's saying something! He can read everything logically as well as knowing when to let his emotions take over even though he's just evolving into them! Strength, speed, knowledge, logic, and Intelligence all peaked and only improving!
