The Birth: When Daily Bugle worker Ben Ulrich and his nephew, Phil Ulrich; also an intern at the Bugle were investigating an old Osborn Industries warehouse, a group of thugs jumped Ben. While searching for cover, Phil accidently discovered the secret headquarters of Harry Osborn - the second Green Goblin. He backed up into a large cannister full of icky green fluid, and got covered in the highly dangerous Stromm Formula. Knowing his uncle was in trouble, Phil quickly donned the costume and succeeded in scaring off the criminals.
He first appeared in Web of Spider-Man #128 and his origin is detailed in Green Goblin #1.

The Alter Ego: Phil Ulrich finished his high school and joined the Daily Bugle as a Journalism Intern. He is hardly one of those "handsome types" and has rather "gawky" features. Like the early Pater Parker, he has the uncanny ability to look like a geek at any given time.

The Legend: After he saved his Uncle Ben from the hoods and went home did he realize the potential of the costume. Apparently, this new costume was designed by Harry Osborn as a new age Green Goblin. It had a lot a hi-fi paraphernelia fitted directly into the costume. Phil thought it'd be "cool" to keep this gear and became the Green Goblin just for kicks.
The suit enhaced his strength to super-human levels. The suit also acts as a shock absorber, preventing damage to Phil's body. Whenever Phil dons the mask, it delivers a massive electrical charge throughout his body, boosting his natural abilities. The mask also hides a device that gives Phil his maniacal laugh. The rest of the gadgets installed in the mask include remote cameras, scanners, and 'glider-cam' vision abilites. And the gloves have been modified to project energy beams and bright flashes from small finger-blasters. As usual the Goblin's mode of transport is the ever-trusty Bat Glider. It was modified to give more power and a camera was hooked to the nose for reconaissance purposes. Phil also rigged a video-game joystick to give him remote conrol access to the glider.
He fought villains like theHobgoblin and the Rhino. He also teamed up with Scarlet Spider to stop the players in "The Great Game".
But it was only after New York Judge Tomb put a contract on his Uncle's life that Phil realized that with great power also came great responsibility. With a new found seriousness in his super- heroeing jig, he along with Daredevil, fought the assasin; Purge and sent a warning to the judge.
Now, a serious crime-fighter, he quickly became a cult idol among the youngsters as the renegade hero who walked the line with his own rules. The popularity also brought Liz Osborn searching for the man behind her late husbands mask. But when this new Goblin saved Liz and her son Normie from the villain Angel Face, she gave him her blessings.
But as fate had it, the curse of the Green Goblin befell Phil Ulrich. During Onslaught's attack the Green Goblin went head-to-head with a Sentinel and the battle damaged his costume beyond repair. That's when Phil decided to ditch the super-hero jig and go back to his normal mundane existance.
