5 Coolest Symbiotes In Marvel Comics (Who Aren’t Venom)

by

Symbiotes, originally introduced as just a different costume for Spider-Man, have become a huge part of Marvel Comics. What started as a simple idea has grown into a whole species called the Klyntar, creating a wide range of characters all linked by the connection between the alien and its host. While Venom and Eddie Brock are the most famous symbiote pair, their popularity sometimes hides the incredible variety within this alien family. The Marvel Universe is full of other symbiotes, each with its own special abilities, reasons for existing, and frightening appearance.

The world of symbiotes is a fascinating part of the Marvel Universe. They’ve inspired some incredibly creative and powerful characters – everything from dragon-like gods to strange and terrifying creatures. This proves there’s a lot more to the symbiote story than just Venom, the well-known protector.

5) Venomsaurus Rex

Imagine a symbiote – like Venom – bonding with a dinosaur instead of a human. The result is Venomsaurus Rex, a truly unforgettable and incredibly strong creature from Marvel’s multiverse! First seen in Edge of Spider-Verse, this prehistoric beast is the enemy of Spider-Rex, a dinosaur version of Spider-Man. On its world (Earth-66), the symbiote merged with a T-Rex named Eddie Brockiosaurus after falling into a tar pit filled with the alien goo. This created a creature combining a T-Rex’s immense power with Venom’s classic abilities, like super strength and healing. Venomsaurus Rex perfectly shows how the symbiote concept can be both wonderfully silly and incredibly powerful, demonstrating the boundless creativity within Marvel’s universe.

4) Extrembiote

Tony Stark, also known as Iron Man, is famous for his incredible suits of armor, and the Extrembiote is one of his most unusual and powerful. During a massive invasion led by the symbiote god Knull, Iron Man combined his advanced Extremis technology with a symbiote dragon he’d separated from Knull’s control. This created the Extrembiote armor – a strange but incredibly potent blend of living organism and technology. The suit allowed Stark to control the dragon and even take over one of Knull’s giant, mind-controlled Celestials, turning it into a weapon. Realizing how dangerous it was, Stark locked the armor away, but it was later stolen and used by the villain Carnage, transforming one of his greatest inventions into a terrifying threat.

3) Grendel

The Grendel is an incredibly old and terrifying symbiote, existing even before most life in the universe. Created billions of years ago by the dark god Knull, it was originally designed as a weapon for a cosmic war against forces of light. Along with its fellow symbiotes, the Grendel traveled the universe, destroying gods and entire civilizations. What makes the Grendel unique is that it doesn’t need a host – it’s a creature of pure rage. Beyond incredible strength and speed, it can manipulate matter and even read minds. Eventually, the Grendel came to Earth during the Viking Age, but was defeated by Thor and trapped in ice for centuries. More recently, it was discovered by S.H.I.E.L.D., unleashing its ancient threat upon the world once again.

2) Carnage

After Venom, Carnage is arguably the most well-known symbiote. It came to be when a young symbiote – an offspring of Venom – bonded with the serial killer Cletus Kasady during a prison escape, merging at a cellular level. This created a being of total chaos, as Kasady’s cruel nature perfectly amplified the symbiote’s already violent tendencies. Because it developed on Earth, an alien world for the symbiote, Carnage was born with unique and greater powers than Venom. For example, it can transform its body parts into blades and other weapons, something Venom can’t do, and its connection to Kasady is so complete that it’s actually in his bloodstream. With no sense of right or wrong, Carnage is a wildly destructive force who believes murder is the ultimate expression of freedom.

1) Big Mother

Big Mother is a powerful, ancient being from the world of symbiotes, connected to their creator god, Knull. She first appeared in a Captain Marvel comic and is the mother of Grendel, a massive symbiote dragon – making her one of the very first of her kind. Big Mother is far stronger than most symbiotes, thanks to her huge size and intense hatred of those who hunt her species. She can also change her shape, often appearing human to trick her enemies. Her story adds depth to the symbiote universe, showing them as more than just alien invaders, but as a cosmic family with a long and complicated history. Ultimately, Big Mother makes the entire concept of symbiotes even more interesting.
