Sentry is one of the most powerful characters in the Marvel Universe, often described as possessing the power of a million exploding suns. His strength is frequently compared to that of Superman, capable of lifting enormous weights with ease and matching the Hulk blow for blow

. He has superhuman strength, speed, endurance, agility, reflexes, and senses, along with near-invulnerability to physical harm such as bullets, extreme temperatures, and even nuclear attacks

. Beyond physical strength, Sentry has vast energy manipulation abilities, including projecting devastating energy blasts, absorbing energy to fuel himself, creating energy shields, and molecular manipulation that borders on reality warping

. He also has powerful psychic abilities, such as telepathy and telekinesis, and has demonstrated the ability to mindwipe entire populations, surpassing even top telepaths like Professor X and Emma Frost

. Sentry's durability and regenerative powers are extraordinary, allowing him to recover from virtually any injury at an accelerated rate. He can fly at incredible speeds, travel to the sun and back in minutes, and teleport instantly in a flash of light
