The inclusion of Hugh Neutron in the game as DLC, particularly instead of his son and series main protagonist Jimmy Neutron, was a response to an ironic internet campaign to get the character in the game known as "Hugh Nation", led by Hugh voice actor Mark DeCarlo and YouTubers The Superverse and Uncle Al, following Hugh trending on Twitter due to memes related to the game's reveal. When Hugh performs his strafe taunt in the game, he can say the voice lines "Hello internet!", "Thank you internet!" and "Hugh Nation!", referencing this push. The showcase for Hugh's moveset, which was aired at EVO 2022, mentions Hugh being included as a "thank you" to the devoted Nickelodeon All-Star Brawl community.
