The Saiyan and the Spider

Thanos

Timeskip to When Thanos' Forces Attack Wakanda

Leek: What do you mean you're opening the barrier?

Shuri: They're starting to spread around the shield, and they're already breaking through.  If they break through in multiple spots, we won't be able to stop them.

I nodded as I looked out the window, seeing the big blue wall split apart.

Shuri: You should go, they'll need more help now.

I nodded, Instant Transmissioning to Steve.

Steve: What are you doing here?

Leek: You need all the help you can get.

I flew into the air, screaming at the top of my lungs as red fur grew on my body and my hair grew a bit.  Red marks appeared under my eyes, and my pupils turned pale blue.  I flew down towards the approaching Outriders.

Leek: Never understood why Thanos used mindless beasts like you.  EVERYONE, BACK UP!

I put my hands together, pulling them apart to make a massive red sphere.  I grinned, throwing it down at the ground, into the middle of the horde of monsters.

Leek: May your dying screams entertain me.  GROUND ZERO!

I fired a blast into the orb, detonating it in a massive red explosion that killed hundreds of the creatures, but I was knocked out of the air by a big hammer.  I got to my feet, seeing Cull Obsidian running towards me, a massive burn mark on his face and missing an eye.

Leek: Man, you have seen better days.  Hehe, seen.

Cull roared and swung his hammer at me, but I just sidestepped it.

Leek: Have we been here before?  I feel like we've been here before.

I grabbed the hammer from him, swinging it around and smashing it into his face, killing him.

Cindy: That was... brutal?

I turned to her, as she looked a bit concerned.

Leek: Sorry Cindy, just... some bad blood.

She nodded, kicking an outrider in the face as I grabbed her by the shoulders, flying into the air.

Cindy: What are you-

Leek: I'm bringing you back to Shuri.  She's not well defended right now, so-

Falcon started speaking into our earpieces.

Falcon: Guys, got a Vision problem.

I looked towards the lab to see a big hole in the window.

Leek: Dammit.  Change of plans.  I can feel his energy, Corvus Glaive's got him.

I teleported us there, just in time to see Glaive about to pry out the Mind Stone with his weapon.  I rushed forward, grabbing his head and flying into the air.

Glaive: Damn you!

I incinerated him with a Ki blast, flying back down to Cindy.  She was helping Vision to his feet as the others arrived, but I suddenly sensed something.

Leek: Shit... he's here.

I spun around, just in time to dodge a blast of purple energy.  Thanos was standing there, a golden gauntlet on his hand, with five of the six Infinity Stones in it... including the Time Stone.  My eyes widened.  That would mean that he took it from Doctor Strange.  What happened to Tony and Peter?

Thanos: It's been a long time, Leek.  You've gotten a lot stronger, you'd have been a valuable member had you stayed on the Black Order.

Leek: And slaughter half the population of worlds?  I'm not like the rest of my race, Thanos.

Thanos: A shame.

I flew at him, punching him in the face.  He grunted in pain, grabbing me and throwing me into a wall.  I spat out blood, looking down at the spike of rock in my chest.

Cindy: LEEK!

I turned to her as she tried to punch Thanos, but he grabbed her by the neck and threw her to the side.  The last thing I saw before I blacked out was a red explosion.

When I came to, I was in a weird place.  It was a tiny planet with a house, a car, and a road that went around it.  The sky was also pink, and below was an endless expanse of yellow clouds.

???: Hey!  You're finally here!

I spun around, seeing two figures.  They both had black spiky hair, one of them was wearing an orange martial arts gi and the other was wearing a version of Saiyan armor.

Leek: Who are you two?

Goku: My name's Goku, and that's Vegeta.  We're Saiyans, like you.

Leek: Where am I?  What happened?

Goku: This is King Kai's planet.  And as for what happened...

Vegeta: You died, erased from existence when Thanos gathered all six stones.

Leek: So... Thanos won?

Goku nodded.

Leek: So why am I here?

Goku: A friend of ours said that in about five years, your friends would find a way to undo it.  So in that time...

Vegeta: TRAINING BEGINS NOW!

He kicked me in the face, leaving me in a crater.

Vegeta: You weren't ready.

Leek: I look forward... to working with you...
