Who created the metal Sonic army in Sonic the Hedgehog 3?

The post-credits scene of Sonic the Hedgehog 3 has left Sonic fans throbbing with excitement as well as speculation as Metal Sonic has finally made his long-expected film debut. The post-cred scene disclosed a whole lot with not just one but an entire army of Metal Sonics, which infers their substantial role moving forward with the future of the Sonic the Hedgehog franchise.

The post-cred also got in Amy Rose’s character, who ends up helping Sonic out in his fight against the Metal Sonic army clones, which in turn possibly sets the roadmap for Sonic the Hedgehog 4. However, with all this being said, a hanging question still remains to be answered: who created the Metal Sonic army in Sonic the Hedgehog 3?

Whodunnit? A few theories surrounding the creator of the Metal Sonics Army in Sonic the Hedgehog 3:

In the Sonic video game series, Metal Sonic’s character was initially designed by Dr. Ivo Robotnik, a.k.a. Eggman. Nevertheless, the film i.e. Sonic the Hedgehog 3 attempts to confuse the fans with the origin story by hinting at various other multiple prospects that might’ve created this metal army of sonics in Sonic the Hedgehog 3.

Dr. Ivo Robotnik, who on the face of it met his deathbed in Sonic the Hedgehog 2, might just still be the mastermind behind all of this. His fixated competitiveness with Sonic could perhaps be the reason that may have stimulated the creation of Metal Sonic as a backup plan.

If Robotnik possibly survived his supposed death, it’s quite probable that he could have behind closed doors planned the upsurge of the metallic army of Sonic from within the shadows in Sonic the Hedgehog 3.

Yet a different persuasive theory links the creation to a character named Gerald Robotnik who is Ivo’s grandfather. Gerald, who is notoriously known for his work on Project Shadow, may have had the capability to build such technologically advanced robotics. His experimentations on Shadow the Hedgehog directly imply he retained the knowledge to scheme on such intense machines.

It is unknown If Gerald may have had a hand in building Metal Sonic as a possibility during his time in prison, but it could surely very well elucidate the technological increase apparent in the Sonic robotic army in Sonic the Hedgehog 3.

Agent Stone, who is Dr. Ivo Robotnik’s loyal sub, is someone else who could also be the creator of the metal sonic army as seen in Sonic the Hedgehog 3. After having spent years at work with Robotnik, Stone could have gained a whole lot of understanding about robotics.

His allegiance and appreciation for Robotnik might have made him continue Dr. Ivo Robotnik’s legacy by having a hand in the building of Metal Sonic after Robotnik’s death.

Other possibilities - G.U.N. and time travel:

The Guardian Units of Nations (G.U.N.), who seemed quite morally vague in Sonic the Hedgehog 3, come up as another suspect. Given their developed resources and history of evolving contingency plans, G.U.N. may have perhaps also designed the Metal Sonic as a defense reaction against probable menaces, which involves Sonic too.

This theory somewhat holds a little bit of weight and power considering Sonic’s intrusion into the headquarters of G.U.N. earlier in Sonic the Hedgehog 3, which may have just activated the release of the Metal Sonic army.

The last probability of who could have made the metal sonic army in Sonic the Hedgehog 3 involves a titillating turn of events that could involve Eggman Nega, who is a descendant of Dr. Robotnik from far in the future.

If the Sonic films picked up ideas regarding the time-traveling occurrences as seen in the video games, Eggman Nega’s introduction could explain the origin story of the metal Sonic army. Eggman Nega's fixation with Sonic and superior technological abilities could make him a prime suspect for the mind behind the creation of Metal Sonic.

The post-credit scene of Sonic the Hedgehog 3 has unlocked countless possibilities to a number of theories about who could’ve created the Metal Sonic army in Sonic the Hedgehog 3.

Right from Dr. Robotnik’s character and his grandfather Gerald to Agent Stone or the G.U.N., or rather to stretch it out even more… could it also be Eggman Nega? The probabilities are huge and endless.

The arrival of Metal Sonic builds upon the eagerness for Sonic the Hedgehog 4 with fans wanting to see how all of these possibilities or which one of these theories end up being true in further installments.
