We see a bunch of helicopters flying over London with Maxwell inside of a box, being carried by one of them. 

Maxwell:  For ye are the temple of the Living God. As God hath said, "I will dwell in them and walk in them, and they shall be my people." Wherefore "come out from among them and be ye separate," saith the Lord. "And touch not the unclean thing, and I shall receive you." 2nd Corinthians 6:16-17. 

Young Boy: Mommy, what's that man talking about? 

https://youtu.be/Yzse69b0qMo

The Crusaders begin to open fire on all of the citizens! 

Maxwell: YES! Cleanse the earth of these sinners! May the lord have mercy, for I! HAVE! NONE!

Integra: Y'know, I think your boy Maxwell's letting his little authority get to his head a little. You should probably have a talk with him.

Heinkel: H-He's just under a lot of pressure. 

Maxwell: You do not deserve God's mercy! If he will return you to the afterlife, THEN I WILL!!

Heinkel: I mean, vords only have as much meaning as ve give zem! 

Maxwell: Sinners will be allowed no quarter! KILL THEM ALL! LET GOD SORT THEM OUT!!!

Integra: You're riiiiiight; ~a lot open to interpretation there!

Heinkel: Perhaps one of us should have a talk vith him. 

Maxwell: I SHALL BE THE NEW GOD OF THIS WORLD!!!! 

Anderson: Aye, let me go have a wee chat.

https://youtu.be/HDHV6Ub36ok

As the Iscariots try to shoot Integra, suddenly they are blown back by six figures, you, Team RWBY, and Seras! 

Anderson: Well, if it isn't Alucard's sidekicks. 

Weiss: WE AREN'T HIS SIDEKICKS! 

(Y/N): And you're not touching Integra! 

Anderson: Do I have to stick more of what I gave ya last time? 

Seras: Why don't you try sticking it in me again? I might like it this time...

Heinkel: Father Anderson! 

Anderson: Context, Heinkel! 

Yang: So, Anderson has his own crew. 

(Y/N): Also, yeah, Seras is a full-fledged Vampire. 

Ruby: How did that work again? 

(Y/N): She sucked my blood. See? 

You revealed some bite marks on you. 

Blake: And you didn't turn into a vampire? 

(Y/N): No, my Hamon and Spin protected me. 

Integra: What about- 

Seras: Some of our men died, but base is secure. 

Anderson: How cute.  It's a shame your blood sugar daddy won't be here ta see it.

That's when Blake heard something. 

Blake: Wait, I hear ... a boat. 

Everyone turned. 

(Y/N): HE'S BACK BABY!

Play from 0:07-end... 

Anderson: I leave for a day and, the Catholics are crusading, while the Nazis are invading! Anderson! Its been only two days but it feels like years! And you!  Uh...How are... I wanna say... Logan? Hey, (Y/N), what's this guy's name? 

(Y/N): Uh ... well ... that's- 

Integra: ALUCAAAAAAAARD! 

Alucard: WHAAAAAAAAAAAAAAAAAAAAT?! 

Integra: Release restraint le- 

Jed: Now hold your horses!

Yang: WAIT! IS THAT GUY A- 

(Y/N): OH MY GOD! 

Blake: This is not happening. 

Jed: I don't know who ya'll think ya are, but mah name's Jed Forest from the South Carolina Baptist Confe-

Alucard: Shhhhhhhshshshshsh...do you hear that?

Jed: Do I hear wha- 

BANG! 

Alucard shot Jed in the head, killing him instantly. 

Alucard: Hm, must have been the wind. 

Weiss: Okay, I can't believe I'm saying this, but I really missed him. 

(Y/N): Yeah, there's some charm to his lunacy. 

Integra: You know what, fuck it! Alucard! Go for a walk. 

https://youtu.be/5fADsF-YX_E

Play from 0:04-2:22... 

Maxwell got up, still inside of his glass box, and saw a bunch of ghouls clawing to get at him! 

Maxwell: HA! Stupid demon zombies! Claw all you want. The only thing that could pierce my Holy Pope Box is the will of God Hims-

A bayonet launches right at the glass box as it shatters! 

Maxwell: AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAARGH! 

Anderson: HAHAHAHAHA! 

Anderson stands above Maxwell with a smirk on his face. 

Maxwell: ANDERSON! ¡¿PORRR QUÉÉÉÉ?!

Anderson: It is the sacred duty of the Iscariot Organization to punish the demon, the heretic... and the false god...

Maxwell could only mutter in horrified gasps. 

Anderson: Also you're a daft cunt. 

Maxwell was grabbed by the ghouls, being dragged to his death! 

Maxwell: Anderson...! Anderson, I don't deserve this...!

Anderson: "Sinners will be allowed no quarter... Kill them all, and let God sort them out."

Maxwell: AAAAAAAAAAAAAAAAAAAAAAAAAARGH! 

Maxwell was impaled by several metal objects, dying instantly. 

Our heroes looked at the carnage going on. 

Weiss: Oh my God. 

Ruby: Look at all those people. 

Seras: This is restraint level zero, huh? 

Integra: These are five hundred years and change of souls that Alucard has consumed... After a while, he stopped actually killing people himself and started hanging around battlefields, letting others do it for him.

Blake: How many has he- 

Integra: Chowed down on? Ooohh, two million... ish...? He calls it his... Ughhh... "#LifeHack"...

Yang: Ha! He would say that. 

(Y/N): Well, let's go and meet up with him. 

As you gys were doing that, Anderson solemly looked at Maxwell's corpse. 

Anderson: I'm not sorry for what I did, Maxwell...but I am sorry I had to do it.

Flashback... 

We see Anderson by his orphanage taking in the Young Maxwell. 

Anderson: And what has brought YOU to our sanctuary of love and brotherhood, my boy?

Young Maxwell: I have a terrible guilt and rage inside me that can only be quelled by the blood and subjugation of the unclean!

Anderson: Oh ho! You'll fit right in! 

End of flashback... 

Anderson: You were a good boy, Maxwell... Shame you were such a shit man.

He then radios in on his group. 

Yumi: Nani? EVERYONE! IT'S FATHER ANDERSON! 
Heinkel: Oh Gott sei Dank!

Anderson: To the Iscariot Order and all surviving Crusaders: Fall back to the Vatican!

Priest: Did he just say- 

Yumi: Fall back? Korehanani no nansensudesu ka?

Heinkel: Father Anderson, ve still have our orders and- 

Anderson: Ya don't have to follow orders when your leader's actin' like a daft c***! Also, Maxwell's dead, so...

Heinkel (faking sorrow) Ooh, zat's a tragedy. 

Yumi: Heinkel, don't weep for the stupid. Ano yarō wa tōzen no mukui o uketa.

Anderson: Exactly. Now follow my orders. There's something I must take care of. 

Heinkel: Father Anderson, zere is no way you can beat Alucard as he is now. 

Anderson: Maybe you're right, Heinkel... But I want to take a stab at it anyway. 

Back with our heroes... 

(Y/N): Hey, Aluca- Oh right, you're not him. You're Count Dracula. Nice to meet you. 

Dracula: The pleasure is all mine, my friend. 

Weiss: Well, when did you become so polite? 

Yang: Yeah, this is weird coming from you of all people. 

Ruby: You know, it makes sense. Alucard is Dracula backwards. 

Integra: I ... well ... I don't know what to say. 

Dracula: It is an honor, my Master, Sir Integra Hellsing... Please... a-just call me Drac.

Integra: I don't think I'm going to do that.

Dracula: As you vish. 

Seras: Uh ... ello ... Maser. It's me ... th-the Police Girl. 

Dracula reached for Seras. 

Seras: EEEK! 

As she freaked out, he pat her on the head. 

Dracula: Ah, good. It varms this long dead heart of mine to see you so grown up... Seras... Victoria.

Seras: EEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE! 

Ruby: Awww, this is nice. 

(Y/N): Yeah, very ni- 

Anderson: ALUCAAAAAAAAAAAAAAAAAAAAAARD! 

(Y/N): OH FUCK YOU, ANDERSON! 

Dracula counters Anderson's bayonets with his sword! 

Dracula: Alucard is not here right now. You face Count Dracula of Wallachia.

Anderson: Call yourself whatever ya want, you crazy vampire bastard! I'm here to cleanse the Earth of your filth, once and for all!

Dracula: Many have tried and failed. Yet, if it is my fate to fall to your blade... then let it be so ... worthy opponent. 

Anderson: Time the fuck out! If we're doin' this... and we ARE doing this...! I'm not gonna come swinging at "DRACULA"... I'M KILLIN' ALUCARD!

Dracula: You do know that it's just my name spelled--

Anderson: OF COURSE I DO! SHUT UP AND BRING HIM OUT! 

He throws his bayonets, only for them to get blasted and his hand shot! 
Anderson: AGH! 

Dracula: Very well... if you insist...

He turned back into Alucard. 

Alucard: Hey there, Padre! How's little Timmy? You know what's good for getting cum stains out of altar boy robes? Holy Water! Did'ya miss me?

Anderson: Like coke after Lent!

Alucard: Wait... are we talking cola or cocai--?

Anderson charged forward, swinging his bayonets at Alucard, who blasted away at him with his guns. 

Then all of his familiars stand in the way. 

Out of them comes Alhambra, throwing his cards, which pierce through Anderson, crying out in pain. 

Then he gets blasted by Rip Van Winkle! 

Alucard: Hope you don't mind, I brought some friends! ...Associates? ...Slaves; I br-- I brought slaves.

Anderson: The more, THE MERRIER!

Yang: COME ON ALUCARD! GO FOR IT! 

Alucard: The runner takes his mark, the starting gun is fired, and it's off to the races, folks!

Anderson starts attacking all of the familiars as much as he can! 

Alucard: He swings to the left! He SWINGS to the right! He's right in the thick of it, ladies and gentlemen! And what's this? Oh, it's a regular ol' bayonet jamboree!

Anderson throws several bayonets armed with explosives, and they blow up familiar after familiar! 

Then a giant beast appears! 

Alucard: And who's this squaring up against him, standing 8'5" and weighing in at 600lbs? It's Biiiiiiiig BARRY!

Anderson stabs Big Barry in the throat! 

Alucard: Better watch out! He's got no gag reflex!

Then Big Barry grabs Anderson's arm! 

Alucard: And he's a hugger! But wait, there's more! 

A whole calvary with spears charge at Anderson, only for Heinkel to jump in and shoot them down! 

Heinkel: YUMI! DO THE THING! 

Yumi: Very well! 

Yumi charged in and pulled out her katana, slicing Big Barry's head in half. 

Yumi: Biggu barī no satsugai wa isukariote soshiki ga kōen shite iru. Go with Christ. 

Anderson: Heinkel! Yumi! I gave you specific orders to-

Yumi and Heinkel: We don't have to follow orders when our leader's acting like a daft cunt! 

Anderson: That's the only time you get to call me any kind of cunt! 

(Y/N): They're sassy as fuck! I really like them! 

Heinkel: Iscariots! Do you vant to live forever?

Paladins: We will live forever! In God's grace!

They started ninja running towards Alucard. 

Ruby: Are they running like- 

(Y/N): Like Naruto, yes. 

Priest: GOD IS GREAT! 

One of them blows himself up! 

Alucard: Ninja catholic suicide bombers... Heh, what a fun day!

Priests: GOD IS GREAT!

They kept blowing themselves up for Anderson to reach Alucard! 

Alucard: Is it racist to say that sounds better in Arabic? 

Anderson: Any last words, monster? 

Alucard: Have you ever thought about carbonating the blood of Christ? You know, give the kids something fizzy to drink, you know, before they wake up in an hour?

Anderson pulled out a box. 

Alucard: Oh sweet! You got some on ya! 

Anderson: I forgive you. 

Alucard: Excuse me? 

Weiss: Did he just say- 

Blake: I don't like where this is going. 

(Y/N): Anderson, what are you doing?! 

Anderson: Everything you've said... everything you've done... I forgive you.

Alucard: Well, isn't that convenient... But it's not up to you, is it? It's up to your PRECIOUS God.

Anderson: You're right. Would you like to speak to him?

He breaks the box, revealing a nail. 

Ruby: What is that nail? 

Heinkel: Yumi, is zat one of ze nails that pierced Christ's body? 

Yumi: Hai. 

Heinkel:  From ze "Don't Fuck Vith This" armory?

Yumi: Definitely. 

Heinkel:  Vere they keep ze Ark of ze Covenant, ze Dead Sea scrolls, and ze ACTUAL Body of Christ?!

Team (Y/N): YOU HAVE WHOSE BODY?! 

Alucard: Ooh, la, la! You've got a nail with some Savior juice on it! What'cha gonna do; stab me through the heart?

Anderson: Not yours...

(Y/N): OH SHIT! 

Anderson: Mine. 

Team RWBY and Alucard: NO NO NO NO NO NO NO NO NO NO NO NO NO NO!!! 

Anderson impales himself with the nail, as Alucard shoots off his head! 

He begins to speak all distorted. 

Anderson: Through the Ministry of the Church, may God give you pardon and peace... And I absolve you from your sins... In the name of the Father, and of the Son, and of the Holy Spirit... Amen. 

He impales Alucard with a bayonet through the skull and a bunch of thorny vines started to glow!

Play from 0:20-end... (Also, God is voiced by SungWon Cho (The voice of Senshi from Dungeon Meshi) and Satan is voiced by Zach Handel (The voice of Charlie from Smiling Friends!)) 

As Alucard comes back, he tears out Anderson's heart along with the nail and crushes it, leaving the priest lying on the ground, beginning to disentigrate. 

(Y/N): He did it! 

Ruby: A-Anderson! 

Weiss: Is he- 

Heinkel and Yumi both looked upset. 

Blake: He's going to die. 

Anderson: It looks like you got what you've always wanted... Alucard.

Alucard: I didn't want this...

Anderson: Ye stole my heart...

Alucard: (tearing up) Ohhh... fu-- fuckin' come on, man...

You were giving a salute for Anderson while the girls were tearing up a bit for him, like they really felt bad for him. 

Anderson: Times like this... I'm reminded of one of my favorite verses... "Whosoever shed man's blood, by man shall his blood be shed, For in the image of God, made He man."

Everyone: And that's from? 

Anderson: Boondock Saints. (coughing and chuckling)  Ahh, my favorite movie...

Alucard: Fucking called it. 

Anderson: Alucard, I hate you... But I understand you. You seek out your own justice to right the countless wrongs you have committed... To find forgiveness... and salvation... But when you find it... Will you accept it? As a man, much like you, once lost, adrift in the mad world... I made peace with my demons. May I tell you how?

Alucard: Of course ... my friend. 

(Y/N): We're all listening, Anderson. 

Ruby: Go ahead and talk. 

Anderson: I- 

Suddenly his head was stomped on by a familiar faec. 

Walter: Said three Hail Marys, ate my vitamins, fucked off, and died, A-men.

(Y/N): WALTER?! 

But there was something different about him. 

He was much younger! 

(Walter is now voiced by Howard Wang (The voice of Anasui!))
