Norman Osborn was turned into the Green Goblin by a chemical solution he had devised based upon a formula originally conceived by Professor Mendel Stromm. The process granted Osborn superhuman agility, strength, speed, stamina, and dexterity, as well as a "healing factor" that allows him to quickly heal even from such lethal bodily damage as being stabbed through the chest by large blades. In addition to these physical advantages, the serum also greatly enhanced Norman's already-above average intellect, making him a bona fide genius capable of making breakthroughs in advanced areas of genetics, robotics, engineering, physics and applied chemistry. The Goblin formula is also said to have driven Osborn mentally insane – defects in his personality were strongly augmented by the serum, resulting in dangerous mood-swings and hallucinations.
The Green Goblin is armed with a variety of bizarre devices. He travels on his bat-shaped "Goblin Glider", an incredibly fast and maneuverable rocket glider equipped with various armaments. Other weapons the Goblin uses include incendiary Pumpkin Bombs, smoke- and gas-emitting bombs crafted to resemble ghosts, razor-edged bat-shaped boomerangs, and gloves woven with micro-circuited filaments which channel pulsed discharges of electricity at nearly 1,000 volts. He wears a green costume underneath bulletproof chainmail with an overlapping purple tunic. His mask has a built-in gas filter to keep him safe from his own gasses.
The Goblin Glider's controls and microprocessor are located behind the head of the glider. The pilot is attached to the glider via electromagnetic clasps on the wings of the glider. It has great maneuverability and is steered mostly by leaning, but manual controls are available behind the head of the glider. The Green Goblin later added radio-linked voice controls to his mask. Its top speed is 90 miles per hour (140 km/h), and it can support about 400 lb (180 kg), though it could lift far more for brief periods. Flying at top speed with a full load and a full fuel tank would deplete its fuel supply in about an hour.
The glider possesses a wide array of armaments, including heat-seeking and smart missiles, machine guns, extending blades, a gun that shoots instantaneously crystallizing goo (only in The Spectacular Spider-Man) and a pumpkin bomb dispenser/launcher.
A grenade used by the Green Goblin, the Pumpkin Bomb resembles a miniature Jack-o'-lantern and, when thrown ignites almost soundlessly and produces enough heat to melt through a 3-inch (76 mm) thick sheet of steel. The Goblin carries these and a variety of other weapons in a shoulder bag he calls his "Bag Of Tricks". The Green Goblin has a range of other "Pumpkin Bombs" at his disposal, including smoke- and gas-emitting bombs. Some release hallucinogenic gases, while others emit a specially created mixture that neutralizes Spider-Man's spider-sense for a limited period of time. All of these are covered in a light plastic mantle that flutters like a ghost when thrown.

Swamp Thing is a plant elemental. After "the Anatomy Lesson," it could be argued that he is in fact a disembodied intelligence without any specific "body" as such, as he can inhabit and animate vegetable matter anywhere(including alien plants, even sentient ones) and construct it into a body for himself. As a result, bodily attacks mean little to him. He can easily regrow damaged or severed body parts, and can even transport himself across the globe by leaving his current form, transferring his consciousness to a new form grown from whatever vegetable matter is present in the location he wishes to reach (he even grew himself a form out of John Constantine's meager tobacco supply on one occasion).
Swamp Thing can control any form of plant life. He can make it move to his will or accelerate its growth. This control even extends to alien life, as he once cured Superman of an infection caused by exposure to a Kryptonian plant that was driving Superman mad and causing his body to burn out its own power.[8]
After the run of Mark Millar, Swamp Thing had also mastered the elements of fire, earth (as stone), water and air, the parliaments of each later killed by the Word, implying that he has retained these abilities and has the power once held by the Parliaments. This has yet to be explicated.
