A pig in George Orwell's book Animal Farm. The more respectable of the two likely leaders, (the other being Napoleon,) it was his honesty and trust that was his downfall in the end.
He introduced the system of government on the farm and was the intellectual force behind the Battle of the Cowshed, and also the windmill. He would spend his time engrossed in his maths and the workings of the windmill, and did not take measures to protect himself and the rest of the farm from Napoleon, and so was driven out.
He represents an alternative system to the way the farm turned out under Napoleon's control. He also represents Trotsky, (Lev Davidovich Bronstein,) a figure of the Russian Revolution who Lenin planned to take control after he died, had he not been murdered by one of Stalin's henchmen by a pickaxe to the head.
