because the baby's monster would be something like Meruem?
Even then, if let's say Tyson hires the whole Zoldyck family, the baby will have a disadvantage just because he'll have to rely on nothing but the beast. Even Meruem needed a Royal Guard, after all, and I'm not seeing the baby have one.
I also think they're ranked in order of birth.
I'm not a big fan of the monsters either… and well, raw power is not everything, they certainly will have to be cunning too. Benjamin looks pretty good for that (I think) and so does Harkenburg… :3
As for the baby, could he even ask the monster to do anything? What on earth is he doing in this succession fight, seriously… ?
I think that the monsters can act independently from the user, so the baby wouldn't necessarily have to give orders. Or he's like the Mannish Boy from Jojo ^^
Or his mother does the dirty work for him.
Oh I agree he's a cruel father xD What kind of father makes his children fight against each other?
I think he did the same to his siblings, so, it's tradition...
