Spider-Man believes Norman to have retained his Goblin powers.
Genius Intelligence: Even before consuming the Goblin Formula, Norman was extremely smart and intelligent, who was especially skilled with mathematics and science, possessing a wide spectrum knowledge of chemistry, the side-effects of drugs and other doses on humans and animals. The Goblin Formula enhanced Osborn's mental capacities and creative talents.
Superhuman Strength: Norman, after drinking the Goblin formula, become superhumanly strong hence he possessed an extreme strength capacity potential. So with that said, Norman, as the Green Goblin, can easily overpower humans by sending them flying and lifting them up with one hand or by hurling them around, and can also lift extremely heavy objects, crush and break through wood panels and templates, can bend metal, and can punch through glass without gaining injury. As shown on many occasions, Norman, as the Green Goblin, can match Spiderman.
Superhuman Speed: Norman can, thanks to the Goblin formula, run and or exercise as well as operate at superhuman speeds hence his overall body equilibrium is also heightened although he isn't nearly as fast as speedsters. With his speed, he can outrun vehicles.
Superhuman Stamina: Norman can, thanks to the Goblin formula, operate or maintain continuous physical motion in activities or simply in his movements for prolonged periods of time without getting tired or weary in the process.
Superhuman Durability: The formula also fortified all of Osborn's bodily tissues, making them far tougher and more resistant to injury than normal humans. While Osborn can be injured by something along the lines of a knife or small conventional bullets composed of conventional material, he is very resistant to great impact forces and blunt trauma. He can withstand powerful impacts, such as falling from several stories or being repeatedly struck by a superhuman enemy, that would severely injure or kill a normal human with little to no injury to himself.
Regenerative Healing Factor: If Osborn does sustain injury, his body's increased metabolism allows him to heal damaged tissue much faster and more extensively than a normal human is capable of. While not nearly as efficient as the healing powers possessed by Wolverine, he can heal from injuries that would prove lethal to an ordinary human. For example, Osborn survived being impaled by his Goblin Glider and made a full recovery with only a scar left on his chest. He also recovered from having over a dozen of his bombs explode while webbed to his chest.
Superhuman Agility: The Goblin's agility, balance, and bodily coordination are enhanced to levels beyond the natural physical limits of the finest human athlete.
Superhuman Reflexes: His reflexes are similarly enhanced and are superior to those of the finest human athlete.
Genius Level Intellect: Aside from his physical advantages, the serum also greatly enhanced Norman's already highly above average intellect, making him a true genius capable of making progress in advanced areas of genetics, robotics, engineering, and applied chemistry that most professional scientists can scarcely comprehend.
Expert Marksman: As the Green Goblin, Norman uses various hand-held throwing weapons such as explosives and razor projectiles which he will throw with great aim rarely ever missing his target. He is also a skilled sharpshooter with various firearms.
Skilled Combatant: He is a skilled unarmed combatant that is capable of using most weapons proficiently.
Class 10; Norman is able to lift 9 tons under his own Goblin powers. Class 100 while in the Iron Patriot armor, Norman's strength is augmented to the point where he can lift up to 100 tons.
Insanity: A downside to the increased intellect and physical capabilities afforded by the Goblin Formula is responsible for Osborn's insanity. While always mentally unstable, the formula has greatly diminished his already fragile grip on reality. His increased mental instability causes him to sometimes be extremely impulsive, not thinking before plunging into a potentially dangerous situation, making it relatively easy to lure him into a trap. Osborn also suffers from the delusion that he is invincible, claiming that "not even death could defeat him" this has caused him to fight when at a severe disadvantage, resulting in his defeat.
The Green Goblin's costume incorporated chain mail in the tunic, giving him further protection from high impacts, such as the punches or kicks inflicted during his battles with Spider-Man.
Iron Patriot Armor: Norman Osborn wears a full battle-suit patterned after the heroic images of Captain America and Iron Man. The battle-suit was cobbled together from StarkTech that had been confiscated from Tony Stark's armory at Avengers Tower shortly following the formation of H.A.M.M.E.R.. However, the armor was disabled by Tony Stark in the middle of Osborn's fight with Steve Rogers during the Siege of Asgard.
Flying Broomstick: The Green Goblin originally rode through the air on a one man, miniature turbo-fan-powered vertical thrust "flying broomstick".
Goblin Glider: He soon re-designed this device into an improved version that he called his "goblin glider", capable of great maneuverability and speeds of up to 90 miles per hour. It was capable of supporting about 400 lbs including Norman's weight (and far more for very brief periods of time). Top speed and a full normal load would exhaust the fuel supply in about one hour. The main microprocessor assisted manual controls were behind the head of the glider, and later modifications added voice-activated radio-linked controls integrated into the Green Goblin's mask. The goblin glider was steered primarily, however, by the weight and attitude of its rider. The Green Goblin's boots locked into the stirrups of the glider electromagnetically.
Explosives: The Green Goblin created and utilized various concussive, incendiary, and other specialized explosives in his career, most in the form of miniature jack-o'lanterns. The Goblin usually carried these in a shoulder bag, nicknamed his "bag of tricks".
Incendiary: The incendiary grenades ignited almost soundlessly and released enough heat to melt through a three-inch thick sheet of steel.
Smoke/Gas: He also carried a variety of smoke and gas-emitting bombs, which were surrounded by a light plastic mantle that fluttered like a wraith when the bomb was thrown. Other gas bombs emitted hallucinogenic gases, and others released a specially concocted gas that could neutralizeSpider-Man's spider sense for a limited period of time.
Flying Razor Bats: The Green Goblin sometimes threw razor sharp bat shaped projectiles which could slice into or ram and impale themselves into opponents.
Electrical Discharges: The Green Goblin's gloves were interwoven with microcircuit-conducting filaments capable of high-frequency electrical power from rechargeable power packs in both his glove cuffs and costume tunics. They had the capacity to discharge for up to five minutes of sustained fire before depleting their power supplies.
Bag Of Tricks: In addition to the common Goblin weapons, there are many others in the bag of tricks like a crescent moon boomerang, a ghost that is stronger than steel, a frog that can emit sonic blasts, and can carry many other weapons in it most of which are unrevealed.
