Harry Osborn enrolled in Empire State University with his friend Gwen Stacy. They rapidly became friends with Flash Thompson. Flash was a star football player and tried to introduce Peter Parker to Gwen and Harry. Peter was worried about his Aunt May being poisoned by his radioactive blood at the time and so didn’t respond to Flash's attempt at introductions very well. Gwen, Harry and Flash didn’t appreciate Peter's seemingly "snobbish" attitude towards them at the time.
Mayor Story Arcs
As a consequence of Peter's apparent snobbish attitude, Flash and Harry tried to annoy Peter. Little by little though, Peter reconciled with Harry and they became friends. That is why when Norman Osborn, Harry’s father, paid for a huge apartment for two, Harry asked Peter to be his housemate and Peter accepted.
Everything in Harry's life seemed great. He had good friends, and a gorgeous girlfriend (Mary Jane). But then MJ dumped him and his father started putting intense pressure on him by laying all of his hopes on Harry. As a consequence of all this, Harry fell on drugs. Harry went to Detox which healed him physically but left him still psychologically weak.
Legacy of Death
After the death of the Green Goblin during a battle against Spider-Man and the discovery of the real identity of Spider-Man, Harry Osborn became totally mad. He decided to follow in the footsteps of his father and become the new Green Goblin. He was defeated by Spider-Man and Harry ended up in a psychiatric hospital.
Harry would regain his previous life. He met Liz Allen and she became his girlfriend. Harry proposed to her and Liz accepted. Harry and Liz had a child together, Norman Osborn Jr.
When Hobgoblin tried to obtain the Green Goblin formula from Harry, Harry decided to again wear the costume of Green Goblin in order to protect his family. But Harry fell into madness and began to attack Spider-Man. During a battle, Harry launched a bomb inside the Osborn Foundation where Norman Osborn Jr and Spider-Man were. Realizing what he had done, Harry regained his sanity and saved everyone including Spider-Man. Harry collapsed dead outside the building, poisoned by the formula. He died in the end.
Brand New Day
The Brand New Day arc actually resurrected Harry (seemingly to have never died so technically he was not resurrected i guess) he was actually studying abroad and getting his life back in order, or as normal as a millionaire play boy with super powers, and son of insane ex-super villain father with ultimate power and control could. Harry comes back into Peters life seemingly never to have died, recovered from his drug addiction and made amends for his actions as the 2nd Green Goblin. As usual he is still quite the ladies man and the foil to his best-est friend in the world Peter Parker. Of course for anyone in Peter Parker's life things are never boring or quiet for very long. Harry is actually in a good place in his life but of course this does not last, he has found found love with a girl named Lily Hollister whose father is running for mayor. His dad, Norman Osborn aka Green Goblin aka Iron Patriot dis mantling S.H.I.E.L.D, forming H.A.M.M.E.R in its place and rising to power during Dark Reign this is only part of Harry's troubles. While he maybe happy a new foe starts creating discord for Spider-man, the Hollister campaign and well everyone in the city. The new mysterious foe is another Goblin type enemy named Menace, of course Peter fears it to be Harry, which it is not, but things do not get better from there. While attacking the Hollister campaign Harry actually resorts to once again wearing his goblin outfit and hopping on a goblin glider to help Spider-man stop Menace, though this goblin "flash back" moment is temporary it still worries Peter. Even more amazing it still get worse for Harry ... one night he walks in on Lily changing, but she was not changing clothes she was changing from her Menace form. MENACE IS HARRY'S GIRLFRIEND LILY. He watched in horror as she was not wearing a costume but she physically changed shape, from the horrid gray horned goblin into the beautiful blond Lily. Lily reveals she was exposed to the goblin formula when she happened to come across a cache of hidden goblin gear but the two work things out ... sort of. They decide she has to somehow be cured of her goblin abilities but ... they break up then get back together get engaged and unengaged and Harry even becomes a father to be when she reveals that she is pregnant with Harry's child. The news of her pregnancy causes him to think differently and do something he hoped he would not have to.
Lily's pregnancy leads Harry to join his father’s regime, Norman had offered him a spot in his "company" but Harry declined, but in his time of need he felt he had to. Harry is surprised to hear his father to be happy he joined but more shocked when he said he was proud of him. Norman even had a plan for Harry which involved something called the "American Son" project. He joins his dad but actually, Harry's main focus is to help cure and protect Lily and their child she is carrying. Harry is actually and unknowingly playing into his father’s hand as he becomes the pawn Norman was hoping for. Spider man infiltrates Avenger Tower to get Harry out of there but is eventually found out, mainly due to Harry calling him out by saying: "That's not your Spider Man."
While Spider-Man is beaten and tortured Harry learns a lot...... I mean A LOT. Revelations galore, it is eventually revealed how truly heartless and selfish his father, Norman, actually is. Norman had planned on using Harry as a new addition to the Avengers not because he would be a good addition but because having a patriotic father son duo as the face of the Avengers would help with Normans public image and relations. He also thought he would seem more palatable to the public with the America Son by his side because of his past. The creepiest part was Normans back up plan for his son, of course Norman planned for Harry's betrayal or his lack of "results" as American Son. He decided that if Harry did not suffice or double cross him he would have Harry become an "example hero" of sorts and actually become a martyr to help his father’s image, basically he would have Harry killed and make it seem like he died a noble death. Possibly the worst revelation is Harry can look forward to the birth of his new baby brother not his son...pretty not cool how that goes down. Menace/Lily has had a further transformation thanks to tampering courtesy of Norman. Turns out Lily never wanted cured and Norman used her to get Harry to join him. So basically Harry is not only heart broken but also betrayed, and used. His experience and turmoil with the Avengers comes to an explosive and brutal conclusion with armor vs armor, ex goblin vs ex goblin, father vs son Iron Patriot vs American Son battle that ends quite unexpectedly. Harry of course dons the American Son armor, but for a more detailed account refer to the American Son character profile.
Sometime later Harry decides to go to a psychiatrist to help him with his recent ordeal while there he is offered narcotics by the doctor (who was unaware of his past addiction issues) and Harry inclines and accepts the prescription. Since the falling out with his father Harry no longer has millions in the bank. He is now a hard working janitor at a coffee shop but a surprise visit from the newly returned Mary Jane Watson reveals how desperate he has become. Harry has had to resort to living in the janitors office. Luckily for Harry Peter actually offers his old room at Aunt Mays house for him to stay at. Harry of course accepts graciously and lets Pete know hes a great friend but turns out it was not Peter...but it was Peter...well his face at least. The real Peter had been kidnapped by his old nemesis the Chameleon, sure he thought he had killed Peter like he does most identities he takes but he always help that person out or those he associates with. Well after Peter dispatched the Chameleon he starts looking for a new place to stay and one stop he makes is at his Aunt Mays. To Peters surprise he sees Harry on the couch getting cozy with his cousins and he realizes what the Chameleon did so Peter leaves still searching for a new home. Back to the danger part of being friends with Peter Parker, while Peter/Spider-man deals with a new foe, Raptor, who thinks Pete is Ben Riley and killed his family he goes after Aunt Mays house. Peter rushes to make sure his family is alright but Raptor is already there holding Peters cousins and Harry at gun point. Luckily during the conflict between Kaine, Peter and Raptor they all get set free and all thanks to Harry tackling Kaine. After the fire is put out, three disappear, and the cops leave Peter sits with an ice pack on his head claiming to have been thrown through the wall. Harry even remarks how much the big hairy guy looked like Peter, if he bulked up a bit and grew a beard.
Like the 616 version he is son of Norman Osborn a rich industrialist and creator of Oscorp and he befriends Peter Parker. Harry is attacked by his father after he originally becomes the Green Goblin and after the goblin killed his mother. Harry goes to live with his uncle for awhile after the attack but eventually goes back to his father. Harry is brainwashed by his hypnotherapist Miles warren to repress memories of previous events like his mothers death, seeing his father transform and countless other traumatic things. During a battle with spider man Harry is able to stop his father by reaching out to him (which was a surprise and it was a surprise it worked due to their history and personalities). Harry is later taken in to S.H.I.E.L.D custody "for his protection" but he is eventually used to bargain with Norman. Due to to mental tampering by miles Warren, Harry develops a secondary personality known as Shaw, Shaw was created because of influence by Norman via his influence on Harry's psychiatrist (oh what a tangled web). Harry eventually becomes the Ultimate universes version of the Hobgoblin this is due to his exposure to the OZ formula during the initial Oscorp explosion. Like his father the Ultimate Green Goblin, Harry posses a goblin form that grants him super human strength, durability, amazing reflexes ,stamina, healing factor, pyrokinesis and limited sanity (its possible this is mainly because of Norman and Miles Warrens mental influence and not the OZ formula but the Oz formula does have an affect because of its side effects). Unlike his doppleganger, the Green Goblin, Harry's goblin form is Orange and has a much more demonic appearance. In a fight with Spiderman Harry tries control himself but eventually loses control goes berserk due to the actions of his hidden persona Shaw. Shaw actually turns out to be a henchman that is supposedly a sleeper agent for Norman, his original conception and intent was to break Norman out of jail by causing Harry to transform and using his goblin powers to do this. In an ever so climactic battle against his father Harry meets his demise, because during the battle Norman surprisingly does gain the upper hand during the fight and kills Harry. In a rare act of humanity Norman realizes what he has done and weaps (a little) and begs the S.H.I.E.L.D Agents to kill him. They shoot the crap out of but he survives because he is seen later escaping from the Triskelion.
