Franklin Richards' powers are vast and extraordinary, making him one of the most powerful beings in the Marvel Universe. His key abilities include:

• Reality Warping: Franklin can manipulate reality on a universal scale, making any thought or desire come true. This includes rewriting matter and energy at the molecular level and creating whole universes or multiverses. He even created his own pocket universe that includes a replica of Earth-616.
• Cosmic-Level Powers: He has power comparable to cosmic entities like Galactus and has been described as a being on par with Celestials, the god-like beings in Marvel lore.
• Psionic Abilities: These include telepathy, telekinesis, astral projection, energy blasts, and precognition. He can read and control minds, create illusions, and resist powerful telepaths like Charles Xavier.
• Energy Manipulation: Franklin can project concussive energy blasts, erect protective force fields, and manipulate fundamental forces like gravity and electromagnetism on a cosmic scale.
• Flight and Teleportation: He can teleport across multiverses and travel through time.
• Life Extension and Resurrection: Franklin has demonstrated the ability to revive the dead and extend human life.

Despite being immensely powerful, Franklin often limits the use of his powers deliberately to live a normal life. His control and full potential are still developing, as comic storylines have shown different power levels for him at various ages. In summary, Franklin Richards is essentially a cosmic-level reality manipulator with vast psionic and energy-based abilities, capable of creating and destroying entire universes, rivaling some of the most powerful beings in Marvel Comics. His powers include reality warping, telepathy, telekinesis, energy manipulation, flight, teleportation, precognition, and resurrection among others. This immense power has attracted many cosmic villains aiming to use him for their own ends. His full potential as an adult remains largely unexplored, but he is considered one of the most powerful mutants and characters in Marvel history. This comprehensive overview reflects his abilities both in comic canon and the Marvel Cinematic Universe portrayal.
