Unraveling Earth-688: Inside Sony’s Spider-Man Universe in the Marvel Multiverse

When fans talk about the vast and sprawling Marvel Multiverse, designations like Earth-616 (the primary comic book continuity) or Earth-199999 (the Marvel Cinematic Universe) roll easily off the tongue. However, one specific number has captured the attention of moviegoers and comic enthusiasts alike: Earth-688.

Officially cemented into multiversal lore through the animated epic Spider-Man: Across the Spider-Verse (2023), Earth-688 is the official designation for Sony’s Spider-Man Universe (SSU). It represents a unique, anti-hero-heavy corner of the multiverse where iconic Spider-Man characters take center stage.

The Multiversal Milestone: How Earth-688 Became Canon

For years, live-action cinematic universes outside of the core MCU existed in a sort of gray area regarding their exact multiversal coordinates. That changed during a blink-and-you-miss-it cameo in Spider-Man: Across the Spider-Verse.

While the dimension-hopping antagonist known as The Spot tests the limits of his expanding portal powers, he accidentally tears open a rift right into a San Francisco convenience store. There, he startles Mrs. Chen—reprised brilliantly by actress Peggy Lu from the Venom films—who reacts with her signature deadpan humor to an interdimensional void opening on her counter. This clever crossover officially stamped Sony’s live-action franchise with the designation Earth-688.

Key Pillars of Earth-688

Unlike traditional superhero worlds driven primarily by classic caped saviors, Earth-688 is defined by a darker, more chaotic tone. It focuses heavily on complex anti-heroes, supernatural entities, and noir-tinged thrillers.

| Film Franchise / Project | Core Focus & Notable Characters |
| :— | :— |
| The Venom Trilogy | Follows investigative journalist Eddie Brock and the lethal protector symbiote (played by Tom Hardy) across Venom (2018), Let There Be Carnage (2021), and The Last Dance (2024). |
| Morbius | Explores the brilliant biochemist Dr. Michael Morbius (played by Jared Leto) as he attempts to cure a rare blood disease, accidentally transforming into a living vampire. |
| Madame Web | Dives into the psychic and mystical side of the universe, introducing Cassandra Webb and a web of clairvoyant heroines tied to ancient destinies. |
| Kraven the Hunter | Rounds out the rogue-centric perspective by bringing Sergei Kravinoff’s visceral tracking and grounded action to live-action. |

What Makes Earth-688 Unique?

The absence of an active, mainline Peter Parker Spider-Man anchoring these specific events gives Earth-688 a distinct flavor. Instead of high school drama or classic neighborhood heroics, the reality tackles redemption stories for monsters, scientists driven to desperate measures, and supernatural threats. It operates as a rogue’s gallery come-to-life, where symbiotes bond with journalists, vampires grapple with a thirst for synthetic blood, and clairvoyants navigate threads of fate.

Whether you view it through the lens of Eddie and Venom’s chaotic buddy-cop dynamic or the broader cosmic web introduced by Madame Web, Earth-688 remains a fascinatingly unpredictable pocket of the Marvel cinematic landscape.
