Takashi Iizuka Calls Sonic 'Like My Own Son' as the Series Reaches 35 Years

Few game characters have remained as recognizable, adaptable, and constantly discussed as Sonic the Hedgehog. Sega's blue mascot has crossed generations of hardware, shifted from side-scrolling speed runs to 3D action adventures, starred in cartoons and comics, and become a major movie character. As Sonic approaches his 35th anniversary, Sonic Team leader Takashi Iizuka has offered a personal perspective on that long history: after spending most of his career with the series, he sees the franchise almost as if it were family.

Iizuka described Sonic as being "sort of like my own son" while reflecting on the unusual length of his connection to the hedgehog. Sonic has existed longer than Iizuka's own children, a fact that gives the anniversary added emotional weight. It is an especially fitting sentiment from someone whose career has been entwined with the character's development since the early 1990s.

His involvement began with 1992's Sonic the Hedgehog 2, where he worked on debugging. From there, Iizuka became a key creative figure in Sonic's evolution through major technical, tonal, and structural changes. That makes his recollections more than a simple anniversary message. They offer a view from within a franchise that has repeatedly had to redefine what Sonic means for new audiences.

A Career Built Alongside Sonic

Sonic's history is not a straight line of uninterrupted success. The character became one of gaming's defining icons during the Mega Drive and Genesis era, but the transition into 3D created both opportunities and long-running challenges. Sega experimented with new casts, alternate gameplay styles, branching stories, open environments, racing, fighting, party games, and a broad range of spin-offs. Through all of that, the central question has often remained the same: how should a character known for momentum and immediacy work in a changing medium?

Iizuka has been involved through many of those transitions. His perspective is therefore shaped not only by landmark releases, but by the difficult stretches in which the identity and future of the brand were less certain. He recalled periods when the series was under threat of being discontinued by Sega. That context makes the franchise's present position particularly notable. Sonic is no longer merely a legacy mascot with occasional game appearances; it has become a multimedia property with a significant global footprint.

For a developer who joined the series during the 16-bit years, watching Sonic survive that many transformations would naturally feel personal. A game franchise can outlast teams, consoles, studio structures, and design trends. Yet the people who contribute to it over decades carry memories of the pressure behind each reinvention. Iizuka's comments suggest that Sonic's longevity is not something he sees as inevitable. It is something that had to be sustained.

Why Sonic Adventure Remains a Defining Turning Point

When asked to identify the game that changed Sonic most, Iizuka singled out Sonic Adventure. His choice points to the enormous importance of the Dreamcast-era title, which represented Sonic's most consequential move into 3D at the time. The game did more than put familiar characters into polygonal spaces. It established ideas that continue to influence how the modern version of Sonic is understood.

Iizuka said the current Sonic franchise would not be the same without Sonic Adventure. It brought the character into a full 3D format, but just as importantly, it gave Sonic a speaking voice. That seemingly straightforward change had major consequences. Earlier games conveyed character largely through animation, music, manuals, visual style, and brief text. A voiced Sonic had a more direct personality, allowing the series to build stories and relationships in a different way.

That approach became a foundation for later games. Sonic was no longer just the fast-moving hero at the center of an arcade-like platformer; he was increasingly a character who could lead cinematic scenes, participate in dramatic rivalries, and carry longer narratives. The results have varied across the series' many eras, but the basic model of a voiced, story-driven, 3D Sonic has remained central.

Sonic Adventure also arrived at a time when platform games across the industry were attempting to find their footing in three dimensions. For Sonic, whose gameplay was tied so closely to speed, curved terrain, precision, and flowing level routes, that transition was particularly complex. The game's importance lies not in presenting a final answer to every problem, but in laying down a template that Sonic Team and Sega have continued to revisit, revise, and debate for decades.

Sonic Adventure 2 Holds a Special Place

Although Iizuka pointed to Sonic Adventure as the most transformative entry, he has also identified Sonic Adventure 2 as the most memorable game he has worked on. That distinction makes sense. The sequel is one of the series' most enduringly discussed 3D releases, remembered for its Hero and Dark story structure, its playable character variety, its Chao Garden, and the introduction of Shadow the Hedgehog.

The game's story achieved an additional kind of longevity when elements of it were used for the third Sonic movie. Iizuka said he was delighted that the film drew on that material. For longtime fans, it is a meaningful example of how Sonic's game history can continue to shape the franchise beyond the games themselves. Characters and ideas introduced in one era can resurface years later for an entirely different audience.

That kind of cross-generational reuse is increasingly central to Sonic's appeal. Newer fans may encounter Sonic first through a film or streaming series, while longtime players may have entered through a Genesis cartridge, Dreamcast disc, or a later console release. The franchise has enough history to offer multiple entry points, but that also creates a balancing act: Sega and Sonic Team must celebrate decades of continuity without making newcomers feel as though they need extensive background knowledge.

The 2020 Film Changed Sonic's Trajectory

Iizuka also highlighted the 2020 Sonic the Hedgehog film as a major turning point, saying its success "definitely changed the course of this franchise." That is a substantial assessment, especially coming from a leader so closely associated with the games. It underlines how important the film's reception was to Sonic's larger cultural revival.

The movie helped put Sonic in front of audiences who may not have been following the latest game releases. Its success showed that the character's appeal could extend well beyond the traditional gaming audience, creating new momentum for the brand and paving the way for further screen projects. Sonic's media presence has since become a significant part of the character's identity, rather than simply an occasional side venture.

This matters because multimedia success can change the expectations around a game series. It raises Sonic's visibility, introduces new fans to familiar characters, and gives Sega more ways to tell stories using the property. At the same time, it increases the pressure on future games to make the most of that attention. A successful movie can bring people to Sonic, but the games still need to give them a compelling reason to stay engaged.

Iizuka's comment about the film also puts the franchise's difficult periods in perspective. Sonic has weathered uncertainty before, but the movie demonstrated that a well-executed adaptation could give the entire property fresh energy. The character's relevance is now supported by games, film, and television rather than resting on a single release strategy.

What Comes Next for the Blue Blur?

There is still limited information about Sonic's next major game direction. No follow-up to Sonic Frontiers has been formally detailed. That leaves fans speculating about whether Sonic Team will further develop the open-zone ideas associated with that game, return to a more traditional structure, or pursue another kind of reinvention entirely.

There are, however, more Sonic projects on the horizon outside the game space. A new Netflix show and another film are expected in the near future, ensuring that the character will remain highly visible while Sega's gaming plans take shape. For a franchise with Sonic's history, the gap between big game announcements can often become a period of intense fan theorizing. Every tease is examined for clues about gameplay, characters, settings, and which earlier era might influence the next project.

Iizuka has indicated that there is more to come for Sonic's anniversary. With 35 years behind the character, that leaves plenty of room for celebrations, retrospectives, announcements, or new projects. Nothing specific should be assumed until Sega shares more, but the anniversary is a natural moment to look both backward and forward.

For Iizuka, that future is tied to a history he has helped build since Sonic the Hedgehog 2. His description of Sonic as being like a son is more than a warm anniversary soundbite. It reflects the rare relationship between a creator and a character whose life has stretched across more than three decades. Sonic has changed forms many times, but Iizuka's comments make one thing clear: the drive to keep the hedgehog moving forward remains very much alive.
