*Phoenix Force: Namor was one of five avatars of the Phoenix Force which granted him the great powers of the Phoenix. Namor only displayed Interstellar travel but as an avatar he should presumably posses the following abilities as well.
:*Interstellar Travel: A Phoenix Force avatar can fly unaided through the vacuum of space, and can travel interstellar distances faster than the speed of light
:*Cosmic Pyrokinesis: An Avatar of the Phoenix can create 'cosmic' flames under any conditions even the impossible ones such as vacuum space or underwater. These flames do not require oxygen to burn, and burn so intensely that matter is consumed without by-products such as ash. It has perfect control over these flames, and they only consume what it wills. Typically they manifest as a raptor or part of a raptor such as a claw or wings, in the case of an avatar.
:*Resurrection: As the embodiment of life and death itself, the Phoenix Force can resurrect whomever it wills.
:*Immortality: The Avatar of the Phoenix does not age and can be resurrected by the Phoenix Force.
:*Temporal Manipulation: An Avatar acting as the Phoenix Force n can manipulate the past across large temporal distances and with a profound knowledge of the causal effect his or her actions will have.
:*Telepathy A Phoenix Force Avatar can project their thoughts into the minds of others and read other peoples thoughts at a near boundless level.
:*Telekinesis An Avatar of the Phoenix can manipulate matter at a molecular scale.
