Marvel: Energy Absorption

Ahmet Abdol (Living Monolith)
The Living Monolith has been genetically altered by splicing his own mutant genes with those of the mutant X-Man Havok. This modification allows him to absorb large amounts of cosmic radiation - although, has Havok absorbs the same radiation, the Living Monolith's powers can be limited when Havok absorbs background radiation that might otherwise be used to fuel the Living Monolith.

Alexander Summers (Havok)
Havok not only can passively absorb cosmic energy from his environment but has shown that he can willingly absorb, store and re-process various other energies from other sources through conscious force of will. He showcased this aspect once when he was thrown into a star. He drew upon its energies to empower himself for the purpose of besting Vulcan.

Carol Danvers (Ms. Marvel)
Her body is capable of absorbing various types of energy for the purpose of temporarily enhancing her own physical attributes. She can augment her strength and energy projection up to the force fo an exploding nuclear weapon. If empowered by enough energy, she can assume her Binary form again temporarily.

Erg
Erg is capable of absorbing all forms of ambient energy.

Gabriel Summers (Vulcan)
Vulcan could absorb virtually any type of energy and channel that energy through his blasts. It is unknown if Vulcan could absorb energy to achieve other effects to increase his strength, physiology, or the like. His energy absorption ability and his ability to wield energy had their limits

Lorna Dane (Polaris)
Polaris has been shown absorbing some forms of energy through her magnetic force fields to temporarily boost her own strengths. Early in her career with the X-Men, she absorbed Storm's lightning blast, Cyclops' eye beam, and Havok's energy beam at the same time, giving her enough strength to propel an entire island from the earth and into space.

Lucas Bishop (Bishop)
Bishop can absorb most types of energy, including magic and psychic, directed toward him. The nature of his powers makes it difficult to damage him with energy-based attacks, while also enabling him to work well with any energy-using teammates. Bishop can also store absorbed energy within his personal reserves, whereupon the energy increases his strength, speed, stamina and recuperative abilities, as well as affording him a measure of invulnerability. The upper limits of his ability to enhance his own physical abilities with absorbed energy is not exactly known but is well into the level of being super human. He is learning to use his energy to temporarily increase his physical attributes in a manner similar to Sebastian Shaw and Agent Zero. This power is passive, allowing Bishop to absorb energy at all times.
