Sonic the Hedgehog 3: Who is Gerald Robotnik?

Video game-based movie adaptations often prove disastrous, but Sonic the Hedgehog managed to avoid joining that club. The rather unsightly first looks at the titular Blue Blur broke the Internet, but Sonic (Ben Schwartz) was redesigned, his live-action blockbuster debut turned out to be a massive hit, and now, his beloved video game series has become the basis for an entire franchise.

Following up both Sonic the Hedgehog 2 and the Paramount+ streaming series Knuckles is Sonic the Hedgehog 3. This time around, Shadow the Hedgehog (Keanu Reeves) stands as the central antagonist, giving Sonic, Tails (Colleen O’Shaughnessey), and Knuckles (Idris Elba) a run for their money. Thus, they’re left little choice but to form an uneasy alliance with their longtime enemy, Dr. Robotnik (Jim Carrey), who’s also set to go on quite a journey of his own.

As revealed in the Sonic 3 trailer, Robotnik will come face to face with his equally scientifically-inclined grandfather, Gerald Robotnik (Carrey). If you’re not too familiar with the extensive and sometimes complicated lore of the Sonic video game franchise, but want to learn a bit about Gerald ahead of Sonic 3, you’ve come to the right place.

Gerald’s video game history

Though his brief appearance in the inaugural Sonic 3 trailer may indicate that Gerald Robotnik is a bit of a goof, much like his grandson, that’s not quite the case. Since making his debut in the 2001 platformer Sonic Adventure 2, it has consistently been shown that Gerald is a brilliant scientific mind. He was specifically sought out to lead the secretive research program Project Shadow under the direction of the United Federation. He accepts, ultimately doing so to unlock the secret to immortality. With trial and error, he eventually creates Shadow the Hedgehog himself.

Unfortunately, his time as one of the leading minds of Project Shadow comes to a swift end. As he completes Shadow, the government gets cold feet and deems his work a danger to humanity. This eventually leads to him being sequestered on Prison Island, where he’s left with no choice but to continue his research under the government’s close watchful eye. Shadow, now completed, initially escapes custody but is soon brought to Prison Island and kept in suspended animation. Dr Robotnik later releases him from this imprisonment long after Gerald loses his mind and is executed.

Maria Robotnik and the future of the Sonic film franchise

Seeing as the movies don’t follow the exact canon of the games, Gerald Robotnik could be up to all sorts of things in in Sonic 3. Surprisingly, there’s a good chance that his story in the film could be similar to that of his video game counterpart.

In addition to potentially aiding in the creation of Shadow the Hedgehog, the plot may hint at the tragic fate of another character: his granddaughter Maria Robotnik (Alyla Browne), who has been confirmed to appear in the threequel in some capacity. She’s the main motivating factor behind Gerald’s decision to join Project Shadow and, unintentionally, his descent into madness.

When he signs up, she’s terminally ill, and he wants to use his research to save her life. Sadly, his involvement in the program leads to the exact opposite. With Project Shadow crumbling, troops from the Guardian Units of Nations, or G.U.N., are sent to the Space Colony ARK, where Gerald is conducting his research. With armed personnel swarming, Maria and her friend Shadow are forced to flee.

Shadow makes it out, but Maria is shot and killed by an ARK soldier, which sends Gerald into a tailspin and manifests in his plan to destroy the world using Shadow. It’s entirely possible he could seek revenge for her death in the film and use Shadow as the means to do so, or she has yet to be killed and will be over the course of the film, setting up a fourth movie.

All in all, Gerald Robotnik, despite not being the most well-known character in the Sonic canon, remains one of its most vital. It will be interesting to see how he’s used on the big screen when Sonic the Hedgehog 3 premieres on December 20, 2024.
