The Seal Prince (or The Prince) is the main antagonist in the 2006 movie, Romeo and Juliet: Sealed with a Kiss. He warned the two families that there should be anymore disturbance or he will send to Shark Island where they will be eaten by Sharky, his minion, the shark that lives there. He wants Juliet to marry him because he thinks she is cute and that he deserves the best. He will use his body and size to kill all those that make him even the slightest mad. The little fish stops him by introducing a female elephant seal who looks as ugly as him, and he was so happy to see his new mate, the princess.
- He bears a resemblance to Dr. Slug from Darkwing Duck.
