¿Who is stronger, Sentry or Ego?

Sentry, also known as Robert Reynolds, is a Marvel Comics character who first appeared in The Sentry #1 (2000). His origin is unique among superheroes: he was initially conceived as a forgotten Golden Age hero whose existence had been erased from the collective memory of the Marvel Universe. Reynolds gained his powers after ingesting a secret serum—"the Golden Sentry Serum"—which gave him the power of a million exploding suns. However, his immense power came with a dark side: a malevolent alter ego known as The Void, which emerges as a manifestation of his deepest fears and mental instability. Throughout his complex story, Sentry has been both a hero and a potential threat, symbolizing the fragile balance between hope and destruction.

Sentry's abilities place him among the most powerful beings in the Marvel Universe. He possesses superhuman strength, speed, flight, telepathy, molecular manipulation, and near-invulnerability. He can regenerate from almost any injury, control light, and even resurrect himself. His power levels are often compared to or exceed those of characters like Thor or the Hulk. Despite his godlike abilities, Sentry’s greatest struggle lies within—his constant battle against the Void, which challenges his mental health and sense of identity. This duality makes him one of the most tragic and compelling figures in Marvel’s pantheon of heroes.

Ego the Living Planet is one of the most unique and powerful villains in the Marvel Universe. First appearing in Thor #132 in 1966, Ego is a sentient planet with the ability to manipulate matter and energy on a massive scale. Ego was originally a planet that formed naturally in space. However, over time, Ego developed sentience and began to manipulate its own physical form. Ego's powers allow it to shape-shift and even create life on its surface. Ego's consciousness also extends beyond its physical form, allowing it to communicate telepathically and project its will over vast distances. Despite its immense power, Ego is often depicted as a lonely and isolated entity. Ego has spent eons drifting through space, searching for meaning and purpose in its existence. Ego's interactions with other beings are often colored by its desire for companionship and connection. Ego has clashed with numerous superheroes over the years, including Thor, the Fantastic Four, and the Guardians of the Galaxy. Ego's powers and strength make it a formidable opponent, and its vast size and ability to manipulate matter and energy make it nearly invincible. Overall, Ego the Living Planet's superpowers and strength make it one of the most unique and interesting villains in the Marvel Universe. Its complex motivations and desire for companionship add depth and nuance to its character, making it more than just a one-dimensional villain.
