After successfully killing the Master mind with the BFG. The doom slayer was transported back to Samuel Haden using the Tether system. But not in the way that he had expected though.
Transport Station Mars
Hayden: You did it. You've won, You stoped the invasion and closed the portal. But it's come at a price. Argent, Vega, This entire operation. You see. I've watched your work, come to understand your motivation. You think the only way is to kill them all, Leave nothing behind.....and you may be right. But we can't just shut it all down! With out Argent Energy it'll be worse! I don't expect you to agree.
Takes The Crucible.
Hayden: But with this! We can continue our work. I am not the villain in this story. I do what I do for the betterment of mankind.
Re-Routing Tether Coordinates.
Hayden: Our time is up. I can't kill you...But I won't have you standing in our way! Until we see each other again...Slayer.....
Doom Slayer: (HAYDEN!!!!)
*Boom*
Some where in Sanctuary
Lilith: Listen up VaultHunters! Rolands found more information on jack. Mordecais at the wild life preserve now. He mig-
*Crash*
CrimsonRaider: Hey Lilith?! You might want to take a look at this.
Lilith: What did you idiots do! Oh shit don't just leave him there! Move him!
CrimsonRaider: We can't Ma'am he's to heavy!
CrimsonRaider 2: Yeah. But look at that gun he's carrying.
As soon as he tried to grab the Slayers gun he sprung to life and was now holding that said person....by their throat.
CrimsonRaider 2: *Chocking*
Axton: Woah there solider. Put him down!
All attention was on him. He just looked at his surroundings. And as he was looking he saw probably the most beautiful girl in his life. Granted he could not tell if the look on her face was that of fear. Or because of how he was acting.
Doom Slayer: W-Were A-Am I?
Lilith: Your in Sanctuary on Pandora. Now put my solider down! *Aims gun at his head*
The Doom Slayer of course dropped the Raider in his hands and walked over to her, yanked the gun out of her hand (Not with out being shot at and bullets bouncing off his armor of course)
Crush
Lilith: That's not good. Uhh I don't suppose you work for Handsome Jack....Do you?
Doom Slayer: Who?
Maya: Sigh-Let me explain the situation to you.
Time Skip After Maya explained the situation to him.
Doom Slayer: Hayden will have to wait. I'll help you guys take down this H-Handsome Jack.
Lilith: Great..What do we call you?
Doom Slayer: Call me Slayer.
Zero: Alright then it's settled we have a new member to our team.
Roland: Alright solider I need you to go with Maya and help Mordecai with what ever he may need. You too cool with that?
Slayer/Maya: Sure.
Roland: Good. Happy hunting.
So after heading over to help Mordecai at the wildlife preserve and finding him and helping him track down blood wing and unfortunately killing her. Maya started to have feelings for the Doom Marine because of how he acted. To her he was a overwhelming powerhouses, but not only that once she got to know him she saw how much passion the Slayer had in him. He protected his friends in combat, Helping people around at Sanctuary. Occasionally having tea party with Tina. She knew that under that cold exterior their was a person that she could love. So the night before they would lead an attack at the Bunker to free/kill Angel, Maya walked over to the Slayers room.
Knock,Knock.
Slayer: It's open.
P.S: To give a little note. The Doom Marine has changed drastically since the time he's been here. Obviously still being the Badass Slaying machine when he needs be. But he's happier now. He has people he can hang around with, that are just like him.
Maya: Hey Y/N?
Y/N: Yes?
Maya: Over the time you been here. Have you found anyone that you have a interest in (Blushing)
Y/N: In what regard?
Maya: You know...The love kind.
Y/N: Well now that you mention it their is one person.
Maya: Really?! Who?
Suddenly she felt weightless as his arm was put behind her waist so she was gently pulled closer towards him.
Y/N: Isn't obvious. It's you. Since the day I first saw you, Your beauty, personality and actions led me to like you even more. And those feelings eventually turned into love.
Maya: I-I wanted to ask you if you could be my Boyfriend.
Slayer: *Chuckles* I would love to.
She then smiles and puts her forehead against his helmet.
A couple weeks went by and after the unfortunate death of angle, Jacks daughter, The Slayer, Maya and the other Vault hunters went after jack to get Lilith back and stop him from opening the Vault and awaking the Warrior. By the time they got there he had Lilith sucking up Eridium and charging the Vault key (Unwillingly of course.)
Axton: It's over jack this is were it ends!
Jack: Hehe...That's were your wrong soldier, you see I'm not just gonna open the Vault. I'm gonna control thanks to the warrior . But first....
He looks at you...
Jack: Why did you kill my daughter?!
Slayer: I'll tell you this once Jack....she asked me to kill her. She was suffering and you just keep using her!
Jack: Oh Bite me! What would you know about Manipulation, or people using other people?!
The Slayer did something no one would expect, not even Maya. He lifted his hands up to his Helmet and slowly removed it.
What they expected to be an grizzly old man, was a person that looked to be in his mid 20s with a scar on his right eye.
Slayer: Because Jack....I've seen it all. Believe it or not I've been fighting for thousands of years. I've lived it. I'll tell you something........You either die a hero or see yourself live long enough to become the Villain!
Jack: Well...You can shove it! I'm gonna get revenge for my Baby Girl! He charged at The Slayer and tried to shoot him with his wrist guns....but as we know, Handsome Jack was never good with guns. So he was ultimately meet with a few punches and jabs to the face. As he was left a bloody mess on the floor with the Slayer about to kill him...The key had finished charging and he was shoved away by a purple dome that covered Jack and Lilith.
Jack: HaHa...Your to late Bandit! I WIN! The greatest Alien power Pandora has ever seen....Is MINE to control!
???:SCREECH!!!
Jack: WARRIOR!!!......KILL!
Zero: Th-
Warrior: Screech.
Zero: That I-
Warrior: Screech.
Zero: That is a big bird!
Slayer: You all stay here...I'll take care of this.
Maya: Yeah...No I'm not letting you do that.
Slayer: Trust me Hun. I fought a being taller than a skyscraper...While completely naked.
Maya: You and I are having a nice long talk about rules from now on...understood?
Slayer: *Starts running* Sorry can't hear you about to kill an Alien bird!
Everyone watched as he simply ran towards it (while dodging a lot a fire being sent his way) Jumping up to its head and Uppercutting the fucker sending it onto It's back while he just pulls out his BFG.
Slayer: Bye.
*Boom*
Jack: No...NO! I can not lose to a child murdering PSYCHOPATH! I WIL-
*Shotgun shot*
Drop
Lilith: Sigh-Finally! He's dead. The people of Pandora are finally free!
Slayer: Not Yet.
Lilith: What do you mean?
Slayer: There are still people out there who want to end the world. Just like "Him".
He felt a hand on his shoulder and he looks at the owner.
Maya: That's why where here love.
Krieg: Yeah! I'm the COMMANDER OF THE POOP TRAIN!!!
Slayer: (Finally a Place were I can truly be happy.)

Maya and The Doom Marine actually decided to Adopt Tina as there daughter and later got married. But....A portal opened up one day in Sanctuary and it was a person who walked out that The Slayer thought he would never see again.
