The series was initially ordered for 20 episodes on March 13, 2014, before being expanded to 26 episodes for its first season.

Series creator Dan Schneider announced on Twitter that a character from one of his previous shows would make a guest appearance on Henry Danger.

Michael D. Cohen, who played Schwoz, was promoted from a recurring role to the main cast starting with season 5 in 2018.

By the time it wrapped, the fifth season's episode order had been expanded multiple times, growing from 20 to 127 produced episodes (with 128 ultimately made) across additional orders announced in December 2018 and April 2019.

Critic Emily Ashby of Common Sense Media gave the series just 2 out of 5 stars, calling it a 'cheesy, formulaic superhero comedy' with little substance.

Patrick Kevin Day of the Los Angeles Times noted that the show's retro superhero concept felt like 'wish fulfillment of a previous generation' compared to the more popular Marvel movies among its target audience.

Henry Danger spawned a media franchise nicknamed the 'Dangerverse,' including an animated spinoff series, a feature film, and the spinoff show Danger Force.

A Henry Danger film was announced in 2017 and eventually premiered simultaneously on Nickelodeon and Paramount+ on January 17, 2025, with Jace Norman reprising his role and also serving as executive producer.

The spinoff series Danger Force, which premiered in 2020, continued the story with Cooper Barnes and Michael D. Cohen reprising their Henry Danger roles alongside four new trainee superheroes.
