Skullfire and Junkpile were from the X-Men 2099.
This is them, two of my favorite characters from the series.
Originally Skullfire was capable of absorbing all forms of
ambient energy particles into his body where he metabolized it to a useable form and then dispersed it in destructive energy blasts. He had no control over this power though and was only capable of using it during moments of great stress.
Cerebra's powers allowed her to trigger his powers at will, but she had to make physical contact with him. After
La Lunatica made him relive Reiko's death, Timothy could control his powers at will. Absorbing the energy of Halo City's powerplants gave Timothy a permanent source of power, but as a side-effect he was constantly glowing with a green light.
When his body was destroyed, Timothy existed as a small sphere of energy. Timothy managed to take a form that resembled his human form. He now was capable of levitation and could absorb and channel the energy around him with far more ease and control.
Junkpile has a unique techno-organic physiology which allows him to construct his body entirely out of metal. This grants him with increased strength, stamina, and resitance to physical injury. He also has
telekinetic abilities so that he can draw and bond metal objects to himself to add to his body or rebuild himself when destroyed
