Complete Monster: While Pete has always been characterized as an antagonist, or at least unpleasant, this version is easily him at his worst. He has no problem essentially declaring himself a warlord over England, looting and pillaging as he pleases, and when he learns that the Prince and Mickey have traded places, he immediately plots to have the Prince killed, and use Mickey as a puppet king. Completely self serving, this Pete has absolutely no redeeming characteristics.
He Really Can Act: The film may only be 25 minutes, but Wayne Allwine utilizes them to really bring out the emotion in both Mickey and the Prince, especially in the scene where the king dies.
Moral Event Horizon: This version of Pete threatening to kill Pluto and abusing his power under the name of the king.
Tear Jerker: The old king's death. Not only does he die unaware of his captain's atrocities in his name, he just seems so broken, and he doesn't even know he's talking to an impostor and not his son, because Mickey doesn't have the heart to tell him.
It also applies to the Prince who didn't find out about his father's death until a passing boater informed him. The grief of losing his father was hard enough, but it was also coupled with the fact that he wasn't there to say good-bye. His long silence after hearing the news made it apparent.
