Initially Eric displayed a shy and quiet persona as well as an admiration for classmate Holly. After absorbing Clark's powers he became far more confident and was evidently pleased by the plethora of praise he received for recovering Chloe's laptop. However his mother and father's fear and aggression sparked a deep seated anger which led to Eric terrorizing fellow students and even attempting to kill Clark.
By the time of his next appearance in "Asylum", Eric's psychological state had worsened as it was obvious he was embittered against Clark for his incarceration but also he seemed to have become obsessed with restoring "his" powers. Eric's killing of his friend Ian revealed that during his "stay" in Belle Reve his aggressive feelings had turned him homicidal.
Powers and AbilitiesAfter "leeching" Clark Kent's powers, Eric received all the abilities that Clark had manifested at the age of fifteen, though he did not display all of them. Though he possessed them for a brief time he became reasonably adept at controlling them. Eric's eventual psychosis and unrestrained rage arguably made him even more powerful than Clark, who nearly always kept his emotions and powers in check.
- Solar battery - After absorbing Clark's abilities, Eric presumably became able to absorb, store and metabolize solar energy to fuel his powers.
- Super strength - After stealing Clark's abilities Eric was able to lift heavy objects and people with ease, demonstrated when he lifted a truck, tossed a full grown man, overpowered police officers and threw cars through walls.
- Invulnerability - After stealing Clark's abilities, Eric was very durable, demonstrated when a blade shattered against his palm and when he smashed a car mirror.
- Super speed - After stealing Clark's abilities Eric could run really fast, demonstrated when he out-ran Holly's boyfriend and sped away from the onlooking students. His reflexes and reactions were also accelerated.
- Healing factor - Eric was nearsighted before he stole Clark's powers.
After absorbing Clark's powers, Eric also possessed Clark's weakness to Kryptonite as exposure to it induced similar nausea and pain to that felt by Kryptonians. His inexperience with Clark's powers also meant that he lacked Clark's practice with his powers, allowing the human Clark to take Eric by surprise in a manner that Clark would not have fallen for. Eric's rage also proved to be a major weakness in that he would act instinctively and without thought, allowing Clark to lure him into the presence of a Kryptonite fragment.
Eric was a quiet, shy student at Smallville High with a crush on a beautiful blond girl named Holly. He was taking a geology class taught by his overbearing, verbally-abusive father Mr. Summers. During a field trip, Eric wandered away. Clark found him standing in the edge of a dam, the protector barrier was shocked by a lightning and Eric fell down. Clark grabbed him as he fell, but was struck by lightning at the same time. Eric was holding a bag with a meteor rock in it and Clark's Kryptonian powers were transferred to him.
Eric used his powers far more openly than Clark ever did. When he thwarted a purse-snatcher, Chloe gave him the nickname "Super Boy" in her first byline in the Smallville Ledger. However, Eric soon became violent and unpredictable.
His father wanted him to submit to tests, his mother was afraid of him and Holly rejected him. At school, Clark stepped in to stop him from attacking Holly's boyfriend, Brent. Eric threw him thirty feet and Clark had to go to the hospital to have his ribs bandaged. When the sheriff came to question him regarding the incident, he tore the street apart in a rage.
Clark realized that, unlike himself, Eric did not have a supportive family and thus could not handle the responsibility to handle his powers and thus sought to reclaim them. Clark guessed that if Eric had his abilities, he also had his weaknesses. He asked to borrow Lana Lang's meteor rock necklace in an attempt to subdue Eric. As Clark attacked Eric with the necklace, Eric attacked Clark with a live power line. The resulting bolt of electricity reversed the original process.
Almost two years later, Clark met Eric again while he was on his way to see Lex, after his friend was committed to Belle Reve. After Eric was taken to Belle Reve, he befriended two of Clark's old foes: Ian Randall, a boy who could replicate himself, as well as Van McNulty, a boy who tried to kill everyone who had been given a superpower by the meteor rocks.
The three of them worked together to defeat Clark when Clark broke into Belle Reeve in an attempt to rescue Lex Luthor. McNulty provided the meteor rock, Ian used it to subdue Clark and Eric leeched Clark's powers again.
When Eric attacked Ian, killing him in the process, Clark recovered and subdued Eric, using the same meteor rock to restore his powers.
- Eric Summers was mentioned in Season Seven's Wrath, when Clark experienced a similar power transferral with Lana Lang, although in this case Lana merely absorbed part of Clark's powers rather than completely taking Clark's abilities.
- Eric's present whereabouts are unknown: presumably he is still in the mental hospital.
- Both times Eric has appeared, the band 'Staind' have had a song of theirs played in each episode. They are 'Fade' in Leech and 'So Far Away' in Asylum
- Eric is played by Shawn Ashmore, who is the twin brother of Aaron Ashmore who played Jimmy Olsen in later seasons of the show.
- For a time, fans assumed that Eric was the show's version of the comic villain Parasite due to his ability to absorb Clark's powers, but this was proven false when Rudy Jones appeared in the Season Eight episode Injustice.
- The power transfer appears to be permanent so one can assume that, had Clark not reacquired his powers, Eric could have held and developed them independently.
- Eric's costume appearance in Leech is similar to Major Zod's outfit in the Season Nine finale. [picture needed]
- Eric was either the first or second human to ever gain Kryptonian powers in history (depending on how one counts Lindsey Harrison, as she was taken by Jor-El 12 years before Eric gained Kryptonian powers, but it's unknown when Jor-El gave Lindsey her powers).
