he is a not bad pig but some times annoyin.he usually think about the others animals like thinking of building the windmill and plan it over night and he miss like a few hour of sleep which is something to be proud of. but remember the harvest part he order the other animals to do stuff whereas he himself just doing nothing and gain the most.
If I remember correctly, Orwells 'Animal Farm' is a loosely based on the Russian Revolution. Napolean is supposed to be Stalin, Boxer represents the downtrodden workers and Snowball is Trotsky.
He's one of the pigs - originally in a dual leadership with Napoleon. I am a bit surprised that you need to ask, as it only takes 2 and a half hours to read the whole book.
although he is seen as quite a positive figure, he automatically assumes that the pigs have control and leadership over the rest of the animals. and he is a bit of an idealist, whose great plans if they had gone through, might have went completely down the drain.
