He was born in the heart of the sun, when a hair of Superman's was attached to a nuclear missile. Superman also suffered radiation sickness fighting Nuclear Man. The vague electrical aura could just be a costume aura, but his only real ranged use of power in the movie was when he attacked the Great Wall, and it's so close up it could be generously described as "some form of yellow, non-physical attack". He DOES match Superman's strength, so saying he's Super Strength is likely accurate, but I'd probably say Radiation Armor for his Primary.
