Evil Mecha just saved Slayer and now the tide of battle could go either way.

Slayer: Thanks.

Evil Mecha: Don't mention it, like seriously don't.

Slayer: Wasn't going to.

Serpent: Rahhh!

Serpent charges at Evil Mecha but he bitch slaps him away.

Serpent: Ow.

Slayer: I guess I owe you.

Evil Mecha: You do, I'll work out what you can do for me later.

Slayer: If it's experimenting on me then no.

Evil Mecha: Shit! Anyway we need to take down your brother. After all the things you and Chaos put him through I think he'll be an easy opponent.

Slayer: Not likely, even though me and Chaos gave him a beat down he still has some trick up his sleeve.

Evil Mecha: I see. Then I'll give my all, you just sit back here and recharge while I deal with him.

Slayer: Ok. Wait take this!

Slayer hands Evil Mecha a hard drive.

Evil Mecha: What's this?

Slayer: Well it's supposed to be for Mecha but since he's gone and your body structure is similar to him it should work. Anyway this hard drive will give you a temporary power boost which will be off the charts, I call it Giga Overdrive. You only have five minutes to use it before it runs out and be carful it could drain you power.

Evil Mecha: Thanks and 5 minutes is all I need. Also where do I insert this?

Slayer: Into your power core.

Evil Mecha: Thanks.

Serpent: Here I come!

Evil Mecha: Idiot.

Evil Mecha then kicks Serpent back then charges after him. Serpent tries to recover but Evil Mecha grabs his arm and rips his arm off.

Serpent: Son of a bitch!

Evil Mecha uses Serpent's arm to hit him in the face with it.

Evil Mecha: Why are you hitting yourself, why are you hitting yourself!

Serpent then gets pissed where he grabs his arm, puts it back, and then kicks him away. Serpent charges at his opponent but Slayer intervenes and tackles him.

Serpent: Seriously, get off of me.

Serpent throws Slayer towards Evil Mecha.

Slayer: Whaaaaaa!

*catch*

Slayer: Thanks. That's two I owe you.

Evil Mecha: Now get off of me.

Slayer: Gladly.

Serpent: Hay fuckers look in front of you!

Evil Mecha: Oh I forgot about you.

Serpent: Rrraahhh!

Serpent charges at Evil Mecha again and Evil Mecha expected this but what he didn't expect was that Serpent had his sword arm ready. He then impelled him in deep in the stomach and threw him into the wall.

Slayer: Evil Mecha!

Serpent: Aw so you really care about the dumb knock off.

Slayer: Tch.

With Evil Mecha

Evil Mecha: Damn he got me, even though it was one hit it did do some damage to my system, he left some of that goo into me which is going to my circuits, if I were to keep up the fight then his goo would spread more into my circuits. Hmmm, ah the drive.

Serpent: Are you going to come out here or what!? He won't last long with my goo in him.

All of a sudden a giant burst of energy comes out of the wall and then destroys the building. All that's left standing is Evil Mecha who is more powerful.

Evil Mecha: Now this something I can get used to!

Slayer: Remember you only have 5 minuets.

Evil Mecha: And as I said before, 5 minuets is all I need.

Serpent: Oh find me in the Alps!

Evil Mecha: How about I send you there!

Serpent: Ooooohhhhh shhiiiiii-

*Pow*

Serpent is punched way back through several buildings and Evil Mecha chased after him.

Evil Mecha: Prepare to have the worst 5 minuets in your life!

4 minuets later because it was too awesome to read!

Evil Mecha: I got to admit, that was awesome, I actually got to thank Slayer for the upgrade.

Serpent: Uuuggghhhh!

Evil Mecha: That enough for you.

Serpent: Yesssss.

Evil Mecha: I think that should be enough for him, and I thought he was going to be hard but never mind, I only got one minute of this so I should finish him off.

Evil Mecha then points his hand at Serpent then powers up a blast.

Evil Mecha: You won't be missed.

*Pow*

Evil Mecha then just blast Serpent's head off leaving nothing there.

Evil Mecha: Done, oh shit!

He then falls on one knee because the drive wore off.

Evil Mecha: At lest he's dead.

Serpent: Not quite.

Evil Mecha: What!

Serpent the rises out of the ground like nothing happened.

Evil Mecha: How, how are you alive?!

Serpent: Ohohohoho, I'm not going to tell you because I think your just going to research it. Anyway, time for you to die.

Serpent then punched Evil Mecha into the sky.

Evil Mecha: He's been playing me this whole time, that bastered! While I just wailed on him he would gather more and more strength from the five minuets and he knew about said five minuets. Son of a bitch!

Serpent then jumps up to Evil Mecha and kicks him into some buildings. He then chases after him decimating him.

Three minutes later of Evil Mecha getting beaten up

Evil Mecha was now laying in the street beaten up. Luckily non of his body parts didn't come off. Serpent then stands over him.

Serpent: Hmp I'm guessing you figured what I was doing those five minutes when you where in that power form.

Evil Mecha: I can't believe I was played like that.

Serpent: Yup and know I'm going to kill you. Maybe after that I should go after that little bitch El-

*Pow*

Serpent: Fuuuuuu-

[There should be a GIF or video here. Update the app now to see it.]

Serpent is punched far away from Evil Mecha, the person who punched him was non other than Slayer.

Slayer: Don't you dare insult Ellie! UltraNova!

A green light surrounds Slayer, he then picks up Evil Mecha and puts his hand on his chest to transfer energy.

Slayer: There, now....

Slayer and Evil Mecha look at Serpent.

Serpent: Oh sh-

They both punch him and then start chasing him. Both of them did not let him get a chance to recover with punches, kicks, power moves, at one point they just kept him in the air knocking him around like a rag doll.

8 minuets later decimating Serpent

Slayer and Evil Mecha both were getting finish destroying Serpent.

Slayer: And Never-

*Kick*

Evil Mecha: Ever-

*Slam*

Slayer: Insult-

*Punch*

Evil Mecha: Ellie ever-

*Kick*

Both Slayer and Evil Mecha the prepared to finish him off.

Slayer/Evil Mecha: Again!

Both of them then kick him away from the city and conveniently the portal Slayer was throw into early was there and Serpent flew right into and it closed. Slayer then powers down.

Slayer: That was, I have no words.

Evil Mecha: Me neither.

Both of them try to walk but end up falling to the ground. Slayer falls first and Evil Mecha falls on top of him.

Slayer: Ow.

Neo and Minato then walk up to their fallen comrades.

Minato: Boy those two are just hard to handle.

Neo: Agreed.

(The end. Well that concludes the three fights with Serpent. Thank you Mecha_Fenix giving me this idea, I think I don't know because it just happened a long time ago.)
