Thanos' voice booms across the galaxy.

Thanos- Team of avengers, you have reached the final round. Choose your challenger who dares to challenge my right as the supreme ruler of the universe, and lays their claim to the infinity stones. Prepare to duel with Thanos.

Scott Lang- Guys, think the same trick will work this time?

Nebula (comms)- Don't even think about trying it, unless you want a quick death.

Scott Lang- I retreat, for now.

Scott Lang teleports back to the spaceship.

Tony Stark- We need a plan, that's not just attack.

Bruce Banner- Agreed.

Tony Stark- I'll go as the main challenger and distract him. As soon as we engage, activate the portal. Land close to him, we can't give him even a second. Make short work of him, we have got this one chance, let's make it count.

Bruce Banner- All for half the universe...

Scott Lang- And half the universe for all?

Talos- Cringe-worthy.

Tony Stark- Time to suit up.

Tony Stark wears his iron man infinity war suit, and also picks up Banner's suitcase.

Tony Stark- This is the final fight of our lives.

Tony Stark- Let's win it.

Tony Stark jumps out of the spaceship, and lands on the battleground with a classic iron-man superhero landing. Tony Stark opens the suitcase, which envelopes him in the hulk suit. He draws his sword and spiked shield. Thanos' hologram appears, far away from him.

Tony Stark- Bring me the gems.

Thanos walks out of the hologram, fully-clad in his battle armor and wielding his double-edged sword. He wears an iron gauntlet in his hand, with none of the stones.

Thanos- Stark.

Thanos is walking towards him, his voice booming across the galaxy.

Thanos- Your chances of winning are one in a million.

Tony Stark- I am sure we could change that.

Thanos- I admire your resolve.

Tony Stark- Cut the trash talk. You killed half the universe, and you are gonna pay for it.

Thanos' helmet's visor drops down.

Thanos- Make me.

Thanos and iron man in the hulk suit charge towards each other, and their swords clash.

Tony Stark- Now!!!

Iron Man blocks Thanos' sword with his spiked shield, but no portal opens.

Scott Lang (comms)- Uh, the portal isn't working.

Tony Stark- What?!!

Thanos punches the hulk suit on the face with his iron gauntlet. Iron Man blasts him back with repulsor rays.

Bruce Banner- The infinity stone's energies surrounding the planet blocks it.

Scott Lang- I created a hole, but its ant-sized. I have only 1 maximizer charge left.

Bruce Banner- I'll go in. Its time for Hulk to smash.

The portal opens. Scott Lang and Bruce Banner go through it.

Meanwhile, Thanos is chopping off the Iron man's hulk suit, but he himself has took little damage. Iron man then grabs Thanos and flies up, coming down to pound Thanos to the ground. Thanos is pinned to the ground, and Iron man is punching him with piston-powered fists.

Tony Stark- 3.5 billion punches still due...

Thanos grabs his sword, and uses it to block the next punch. Iron man is using all his power, but Thanos is pushing him back, and manages to stand up.

Hulk- Hulk Smash!!!!

The portal has opened behind Thanos, and Hulk ferociously charges him. Thanos' sword has fallen, but seeing Hulk's pattern, he manages a well-placed uppercut with his iron fist, which sends Hulk flying to the ground.

Tony Stark- Hulk!!

Hulk is about to attack, but pauses.

Tony Stark- Suit up.

The Hulk suit detaches itself from Iron Man, and goes towards Hulk. Thanos picks up his sword and tries to charge against him, but he suddenly starts.

Antman- Hey there, feeling an itch in your ear? I'll scratch it for you, if you don't mind.

Thanos scratches his ear.

Antman- Ooh, that's a big finger you got there. But where are the stones?

Thanos- You can never win, pest.

Antman- Look out for yourself first, purple king!

Thanos looks up, to see Hulk's fist coming towards him. Hulk attacks with his sword, Thanos tries to defend but his sword gets cut in half. Thanos fights with the half-sword, but Hulk's sword converts into a whip,, which Hulk uses to snatch and throw the shrapnel out of Thanos' hands. 

Thanos- Bare fists it is, then.

Thanos charges with his iron gauntlet, and Hulk and Thanos' fist connect, resulting in a shockwave. The gauntlet is unimpacted, but some of Hulk's suits break off. 

Iron man- Feeling too hot-blooded today, tyrant?

Iron man releases a jet of cooling spray on Thanos' fist, which converts to ice. Thanos shakes it off, but iron man blasts him with repulsors as well. While Thanos tries to defend himself from the ice and repulsor rays, Hulk rises up again. Iron man stops firing, and Hulk jumps up and smashes Thanos. Thanos punches Hulk, but Hulk blocks with his spiked shield which cuts Thanos. 

Thanos punches Hulk with fury, but Hulk also fights without restraint. Suddenly, a sword pierces through Thanos' chest.

Tony Stark- You aren't inevitable.

Thanos- Think again.

Thanos vanishes in wisps of blue energy, much like with the space stone. The infinity energies' force field around the planet stops to loop around, and then completely disappears. Titan is once again the barren red planet it was, with no sign of any life.

Scott Lang- Guys, where did he go?

Tony Stark- Where are the stones?

Hulk points towards a spot on the ground.

On it lies an infinity gauntlet of dust.

Scott Lang- Did we just lose?...again?
