Rocky is seen as a mischievous animal. When he is first seen it is trying to get himself some food from a trash can, however, he is soon interrupted by Jack-Jack. Due to this, Rocky is also shown to have a temper as he tried to fight Jack-Jack after Jack-Jack tossed his food away. He is proven to be fearful of Jack-Jack after he almost destroys him and he runs in terror at Jack-Jack's newfound powers.
Rocky looks like your standard raccoon. He has gray fur with a light/dark gray-striped tail. He has black hands, feet, and claws. His stomach is light gray along with his face. He has brown eyes with black fur surrounding his eyes, which prompted Jack-Jack to think he was a bad guy. Around the black fur is white fur above the eyes, with his ears being white as well.
Rocky is seen in the Parr's backyard rummaging through their trash. Since Rocky is a raccoon, he has a black "mask" prompting Jack-Jack to thinking he's a burglar. Jack-Jack goes outside to go stop Rocky from "stealing". This leads into a fight where Jack-Jack executed many of his powers to combat the raccoon's persistence and elusive nature until the raccoon ran for his life, eventually getting away after Bob grabs Jack-Jack, seeing that he has powers.
In the game, the raccoon is a fight for Jack-Jack, but he has two other raccoons to help him and cheer for as he fights the super baby. Rocky's boss title in the game is "Raccoon", which might be due to the game being released before the Incredibles 2 album was.
- The raccoon's name, Rocky, was revealed from the song that plays during his fight with Jack-Jack titled Rocky vs Jack-Jack, on the Incredibles 2 album. In the film itself, the racoon's name goes unmentioned.
- The idea of having Jack-Jack fighting against with a racoon and showing the racoon his superpowers was originally pitched by Teddy Newton for the original film. It was dropped as there wasn't room for it, but director Brad Bird loved the idea so much that he resolved to use it in the second film.
