He then starts to fight Thugs with Snipers as he throws them off the balcony and webs them in a cacoon. As Y/n was Fighting the Thugs, Iron Man comes flying in with a new suit on.

(Don't Own Art)

Iron Man: Hey Kid, Was a little held up but now I'm Here; What's the plan?

Y/n: Okay, Mysterions are arming a bomb. We need to stop that and Mysterio.

Y/n then notices Mysterio was using the train to escape. Y/n then goes after him.

Iron Man: You Go get him kid, I got these guys

Y/n then continues to go after Mysterio. He then slingshots into the train. Mysterio turns around to see Y/n alive and kicking it. 

Mysterio: At Last...

Y/n: Sorry I was late, It's kinda my thing.

Mysterio and Y/n run towards each other as they begin to fight. Y/n punches Mysterio in the ribs and then in the helmet. The next attack was blocked by Mysterio as he punched Y/n back with the seismic Gloves. Y/n recovers from the attack and Slingshots towards Mysterio and kicks him into the next Cart. Mysterio then notices a crack in his helmet. He the calls up some drones to help.

Mysterio: Let's Shake things up...

Mysterio then release the illusion gas as Y/n's Environment began to morph around him. The area was now black as Y/n was surround by illusions of his recent past; The Sinister Six. Y/n then trusts his Spider senses and runs in eyes closed. Y/n jumps off of the illusion Shocker and punches illusion Vulture. He then Illusion Rhino at illusion scorpion and knocks back illusion Electro. An Illusionary Robotic arm tries to grab Y/n but he slam slams it back at Doc Ock.

Mysterion Thug: Boss You're in the Strike zone

Mysterio: no. FIRE. ALL. THE DRONES. NOW!!!!!!!!!!!

Lots of drone Swarm in the train as Y/n fights off the drones towards the point the roof of the Train was demolished. Mysterio then tries to shoot Y/n, but he shields himself from the bullet and throws a drone at Mysterio knocking him back towards the control deck and into it. Y/n then kicks him the face and grabs him.

Y/n: It ends here, Beck.

Mysterio: No...

Y/n then knocks Mysterio unconscious. Y/n Then notices the wasn't stopping

Y/n: Okay, Time do the thing Tobey told me not to do when stopping a train.

Y/n then gets in front of the train and shoots webs on both ends using them to stop the train.

(something like this)

Y/n began to stop the train. As it went out the tunnel Y/n notice that it wouldn't turn but go straight and fall off. As the train began to stop Y/n was using all his strength to stop it. When the train stopped Y/n had lost consciousness and fell. As Y/n nearly fell to he demise Iron Man flew in and caught Y/n.
