The new Sonic movie The Hedgehog has captivated all the followers of the character with its incredible story and action-packed moments, so much so that it has become one of the most successful video game movies of all time due to its good reception in Box office during launch. During the film's trajectory (SPOILERS below) we can see mainly the fight between Doctor Robotnik and Sonic, but other characters also appear as his good friend Tails, and known enemies of the franchise.
Although these characters have given the film a lot of life and action, unfortunately not one of the most expected in this installment appeared, and it is Knuckles, the red hedgehog that is represented by his serious personality, and that also forms Part of Sonic team in video games
«For this first movie, we were really just watching the 1991 game and we only saw where it all started and we kept it simple. I really try to catch Sonic and Robotnik and establish their rivalry because I don't … I mean, I love it … There are a lot of great characters in the Sonic universe, but the most important thing is just set up Sonic and just tell a bit of an origin story with him, and do it in a way that really makes everyone fall in love with him as a character and just look for more. And then, if all goes well, then we can open it and bring some of these other characters that fans know and love. And yes, I mean, nobody is more excited than me to have that opportunity ».
Considering Fowler's words, the production wanted to capitalize on Sonic's origin, so it would be very hurried to place several characters that could form other stories in the future, such as Knuckles. Likewise, he affirms that if everything goes well and a sequel is confirmed, we may see this character and others in the next stories.
