Unclear question. I added a brief description of the characters, Hop Frog, and the King in the short story “Hop-Frog” by Edgar Allan Poe.
Explanation:
Hop Frog: this character plays the protagonist role which is evident from the fact that he came to save the day by his revenge plan against the King despite his unimpressive physical traits.
The King: His interactions in the short story shows that of an antagonist who is keen at belittling others. For example, on page 1 line 2, the narrator tells us that he lived “only for joking".
