Without waiting for Chief Pratchett response, Spiderman swing his way into the Kingpin's building while avoiding all the bullets that is flying in the air. As he climbed up the wall, he can from the window the huge messed in the building caused by the bullets and explosions with fire burning all over the place.
Hearing the sound of explosions and gunfire from upstairs, Spiderman quickly speed up his ascend towards the sound of the commotions. As Spiderman smashed through the window, he can clearly hear gunshots and loud shout of people coming from the hall of the building floor.
Spiderman quickly run through the corridor towards the source of the sound and when he reach the large hallway the scene stunned him causing him to quickly lift up his mask exposing his mouth and start vomiting at the spot. What he saw was a disturbing sight as there are a lot of bodies lying dead on the floor with gruesome wounds on their bodies or missing limps. The area was a total mess with fires burning in several areas of the hallway.
Before Spiderman could compose himself, suddenly he receive a warning from his spider sense. A huge fireball is flying towards his location, quickly dodging the attack Spiderman with a determine voice said "I am not going to let you escape this time! You will pay for what you did to all the people that you have murdered!"
Spiderman started spraying his webbing around Green Goblin's body and finally encasing the monster like a cocoon with his special webbing fluid.
Green Goblin struggle in the cocoon for a moment before he started releasing high temperature all over his body. As Green Goblin successfully teared the through the webbing he shouted "You annoying insect!".
"Spiders are not insect, they are arachnid" Spiderman replied before delivering a kick on Green Goblin's chest which caused Green Goblin to step back due to the impact.
Before Spiderman could jump back to safety, Green Goblin grabbed Spiderman's leg with right hand and slammed him to the floor. "I got you now" Green Goblin said menacingly.
Before Green Goblin could continue his attack, Spiderman shot his webbing to Green Goblin's face covering his eyes. Ignoring the webbing on his face, Green Goblin lifted Spiderman above his head with his right hand and throw Spiderman towards the wall like a ball before tearing the webbing off his face.
"Ouch!" grunted Spiderman as he is send smashing through wall into a room in the building. "I have to play it smart, since he is much stronger than me. I need to buy some time before the others arrive and give me a hand" Spiderman said to himself as he struggle to get back into the fight.
"Let me burn everything Kingpin owns down to ashes, he has to pay for what he did to me. So lets bring Kingpin down together" Green Goblin negotiated with a nasty grin.
Spiderman continued his barrage of kicks and punches toward Green Goblin striking all his body with all his strength he could muster. Spiderman is forced to stop his assault as Green Goblin started producing flame all over his body, destroying the webbing that trap him.
"Damn, he is tough!" Spider said to himself as he retreated to a safe distance avoiding the burning flame and high temperature.
Green Goblin laugh maniacally "Impressive Spiderman, obtaining your DNA will perfect the serum and make me unstoppable!". Green Goblin rushed toward Spiderman, grabbing Spiderman's neck as both of them smashed through the walls and before throwing him back into the hallway creating a small crater on the floor due to the impact.
Spiderman exclaimed "Damn you are too clingy!" as Spiderman stood back up to face Green Goblin as whole body feeling heavy like lead. As Spiderman poised himself to continue the fight with the approaching Green Goblin, Nightwing came barging in kicking Green Goblin away from Spiderman sending him crashing into the wall.
....
"Looks like I just come in time! Good job Spiderman. Take a breather before you check on the others while I take the trash out" I said to Spiderman as I look towards Green Goblin.
Spiderman argued "We should work together to take him down!"
"Go help the others to capture Kingpin, I will slow him down until you come back with back up" I replied.
Hesitating for a few second, Spiderman finally nodded his head saying "Stay safe" as he head upstairs.
Green Goblin approached me in a intimidating manner saying "Only you and me Nightwing, I will kill you and strip your flesh from your bones piece by piece and I will enjoy it" with his eyes and hands glowing as he come charging towards me.
"So what about your son?" I said as I avoided his attack by jumping over Green Goblin and delivering a kick to the back of his head sending Green Goblin smashing into the floor head first.
Green Goblin quickly got back up and started shooting blast of fire with both of his hand extended forward laughing "So what about Harry? He should be proud to be in my legacy! Spiderman is more of a son to me compare to Harry since I create him. Harry is my property and since he is my business competitor he must die too. I will be the only Osborn people will remembered in history".
Avoiding Green Goblin attack by jumping around the room, I replied "You are going to kill him just because he threaten your legacy. Damn you are hard man to satisfy!" as I retaliate by punching him in the stomach causing Green Goblin to struggle to catch his breath.
"That is impossible. How are you much stronger than me?" Green Goblin say as he gasped for breath.
Punching Green Goblin's jaw, I replied "I take your serum" causing Green Goblin to fall down on his back.
Green Goblin became enraged by my reply shouting "How dare you trick me!" as flames of fire started erupting from his body. Green Goblin quickly got up and tried to grab both my arms with the intention of burning me to death with his flame. "You will die now!" Green Goblin said confidently.
Before Green Goblin is able to grab me, I delivering a right kick towards Green Goblin's jaw sending him staggering backward before I followed up my attack with a left side kick toward Green Goblin's chest sending him flying backward. This attacks was done quickly to avoid the raising temperatures and flames emitted from Green Goblin's body.
As Green Goblin is flying backward in the air, I pushed the advantage I had by rushing towards Green Goblin and deliver a spinning chop kick from above towards his chest sending him crashing back on the floor followed by throwing explosive wingdings.
The explosive wingdings exploded embedding Green Goblin further into the floor, at this moment my spider sense started warning me of incoming danger. Suddenly the glider came crashing in flying directly towards me, avoiding the glider I throw several explosive wingdings destroying it.
Green Goblin groaned as he struggle to stand back up before rushing towards me with flaming hands shouting "I will kill you!"
"I am getting real sick of listening of you wanting to kill me" I said as I avoided his attack and started delivering punches after punches powered with venom blast toward Green Goblin's head causing him to stagger backward towards the window with each blow. As the last blow send Green Goblin crashing out of the window plummeting downward. I quickly jumped out of the window and delivering double fist punch powered with venom blast towards Green Goblin sending him plummeting at a much faster speed.
Green Goblin came crashing down head first on the pavement creating a huge crater sending clouds of dust flying everywhere with a shock wave sending everything flying backward. As the dust settles, Green Goblin's body can be seen slowly shrinking with his green skin and horn started slowly turn back to normal. Looking badly injured, Norman started coughing blood and is having huge difficulty to breath due to his injures.
As I approached him, Norman said in a accusing voice "You have done a huge misdeed, I could have make a huge contribution to mankind...." before finally falling silent.
Looking back Norman, I gave a moment of silence and a quiet little prayer for him. As I headed back into the building, I said to myself in a soft whisper "Thank you father!".
Extra note : Green Goblin strength is around 36 ton
