See….the thing about this is that he was smart enough to like, time scale all of Alternia to be the evil destruction it was. But now he is raging to help out the others?

The only way I can see this happen is that the “Raging English” was the newly hatched one, and is destroying everything because he is an ass. And the one that took control of Alternia was a more mature one….and that is the one they have to fight.
