After reading Never Look Back By FallenQueen2 this hopped up

Xander as a highly successful but unliked Cop/Agent with a dark past, just like Tony DiNozzo and Marty Deeks, who continues to hide behind the 'Xander' mask {jokester..} with no one bothering to look any deeper.

During the course of his life/career befriends Tony and Marty, the three of them becoming close supportive/protective family/brothers/friends & when they are together, they all know the full scope of each others history, issues and pain so there are no masks, recriminations, secrets, misunderstandings, lies, judgements...etc keeping each other grounded and sane

How would the NCIS teams react when they find out during or after an op?

Bonus Points if Xander is related to Steve McGarrett Or Danny Williams from Hawaii Five O.

Alternatively, they could all actually be relatated by blood/marriage..? 

The challenge can be either:
1. When Q feels bored, he decides to go to the Buffy-verse(with however many crossovers as anyone who writes this wants) to play as a human, namely, Xander Harris.

-Or-

2. When Buffy stops Larry from punching Xander in the Halloween episode, instead of going as a soldier, he decides to go as the All-Powerful, All-Knowing, Q(from the Star Trek-verse). Q, after viewing Xanders life -past, present, and future- tweaks the spell so that Xander keeps all of the power as a Q along with the knowledge of how to control it and (so he doesn't have to be told off that he didn't) the rules/laws/regulations/etc of the Q Continuum.

Requirements:

1. It can have as many and any crossovers as they want.
-I've gotten quite fond of those crossovers with the Percy Jackson universe, so if whoever writes this wants to, Xander/Q can help out there. He can even make the Gods of that universe/reality their own plane of existence and teach them how to shed their physical forms like the Ascended Ancients/Alterans did in the Stargate universe.

2. When/If he goes to the Stargate universe(if it's not already in the Buffy-verse, because that episode with the alien in season five of Buffy can explain the connection between the Buffy and Stargate universe), he has to make sure Daniel is exempt from the Ascended Ancients rules and non-interference policy, like, oh, i don't know, give him his own group of loyal Ascended Beings maybe.

3. The Balance- There is no Balance, that's just the Powers that Be passing information to both sides and so they basically make sure niether Good nor Evil wins, wanting to keep their jobs and the power that comes with being the PTB.
-Whistler can't suffer punishment- He's only the messanger.

4. Anything and everything goes

What if Xander had a down to earth hands on Grandpa that he often stayed with who was a former Marine & FBI Agent that had escaped from his old Watcher family, who gave him a thorough grounding in magic, supernatural, demonic, paranormal, hunting, law, self defence, tactics, weapons, wilderness survival-tracking, money, people reading, problem solving, forensics, languages, medic, investigating, field psychology, carpentry, mechanics, handyman, security...etc

Helped ensure his grandson not only survived but thrived in both worlds with practical life skills, particularly when he realized that Xander is the first in a completely new magical bloodline like melinda warren was = also helped him secure proper accurate records outside Sunnydale, the Harris & Willow Interferences under legal birth name{education(distant learning), medical, legal, financial, employment, personal...}

How would all this change Xander for the better, particularly with Grandpa not liking Willow and therefore not allowing her, or anyone else, to influence his Grandson unduly in any shape or form so that Xander can form his ownself & opinions

Challenge – Alex Kent formaly Xander Harris 

• Set during high school for both of them though Alex can be older or younger than Clark

• Both Alex and Clark work through their issues through various mediums = art, music, stories, carpentry, mechanics, cooking...

• Alex is a metahuman with a heightened healing factor, the gifts of Empathy and a more active power such as Force Fields...etc {though nothing that would make everything simple like Telepathy} – Clark also discovers his abilities quite quickly once they meet due to an accident

• Deeply mourning the deaths of best friend Jesse who was like a brother and his secret military brat Boyfriend aka first love = both of whom were the only ones who previously knew of his metahuman abilities

• The Harris's are killed in a fire {doesn't really mourn them, instead mourns for what should/could of been if there was no abuse, neglect, indifference, alcoholism..etc} = does inherit a reasonable amount of money from insurance once the debts...etc are paid

• Alex belongings reduced afterwards to Boyfriend Ninja Motorcycle, Jesse Guitar & a chockablock duffle bag with his clothes, Jesse-Boyfriend Jewelry, Essentials, CD storage books, personal folder{his true Ids-records-paperwork-licences...}, His-Jesse-Boyfriend Journals{packed with art-lyrics-keepsakes-photographs...}, hunter journal, blessed weapons, first aid kit, supplies, odds & ends...etc

• Alex having had experience & previously earning money in the darker aspects of the world – fight clubs, stealing, drag racing, hustling pool-darts-cards, stripping...etc making him much more likely to spot various human threats early as well as call anyone and everyone on their BS or unwarranted hurting/pushing of Clark

• Manages to make his way to Smallville after the Harris's deaths where he's adopted by his aunt and uncle {the Kents} which leads to a new surname, nickname, paperwork, licences, accounts, practical wardrobe, calmer personality{no more joker-slacker facade}, full medical, full education testing, gifting Kents with half of his parents insurance settlement so less money problems for them

• Or alternatively Alex meets Kal whilst living in metropolis, becomes confidants and helps him out - so much so that Clark calls him once he's back to himself and Alex moves to Smallville to be closer to him to help with his issues - afterwards Martha recognises him as her nephew and it then leads to the new Surname, nickname, paperwork...etc

• Alex & Clark bonding very closely as brothers with unconditional and beneficial support, brotherly love, trust, friendship, acceptance, truth, clarity, lack of secrets...{outside of their powers possible secrets could be taking college classes, being stolen at birth or lab created{Alex}, teenage pregnancy...}

• Both of them end up forming a good solid relationship with Lex Luthor despite everyone else's protests which leads to one of them initially dating him and the other dating Bruce Wayne or Oliver Queen as Lex doesn't go crazy or evil though he does still die

• Clark gets over his Lana crush much quicker as he realizes that it all based on fantasy and not reality as well as lets Chloe down gently about her crush

= Xander as the unknown son of Nathan Ford

= Relationship gets found out in one of several possibilities 1) both nate & xander are kidnapped as revenge - force nate to discover & then watch another son die, 2) meet whilst unkowingly doing the same job, 3) xander as the target of the teams con thanks to the manipulations of a mutual enemy

= Xander had a hard childhood thanks to at the very least abuse, neglect, social isolation & loss of a brother, best friend and first love/boyfriend

= Xander slow to trust his dad thanks to his childhood, Nate's own Alcoholism and Sophie hold on Nate{has issues with women thanks to relatives, crap friends & bad ex's}

= Xander as a mix of Nathan, Eliot & Parker in Skill set with his own small business as a hobby{Gay BDSM club-Tattoo Parlour-Carpentry Furniture Store-Motorcycle Garage...}

= Alternatively Xander as a blind hitter who no one knows is blind thanks to his ability to compensate

= Xander slowly forming a strong bond with the team minus Sophie & in particular Eliot as either a Mentor/student, Lovers, Brothers or Best Friends

= Alternative Universe - mpreg, shifters, sentinal, BDSM...etc

This is based on the Transformer Movie - 2007

While doing slaying research Xander came across a story about two metal demons that fell from the sky. One demon was in search of a magical item that could be used to rule all. While the other demon, an Atobo, was here to stop the other metal demon and return the magical item to it's true home.

With the aid of the Slayer the Atobo was able to destroy the other demon but not without it's own lost of life.

In the book Xander is reading he also find woodcarving made of the Atobo and the symbol it wears.

When Xander visit Ethan's, he fined out he's out of luck as the last toy gun walks out the door. With nothing left to lose, Xander decides to dress up as Atobo. So after buying something from Ethan, Xander makes a costume including the symbol that Atobo wore.

When Ethan completes the ritual Xander is turned into a robot, to be exact an Autobot. Since he was a generic Autobot he does not have the memories of any other Autobots but he can transform into a vehicle of some type.

After the spell is over Xander retains the ability to transform into a robot and into a vehicle.

Fast forward to the present. Megatron is dead. The Allspark is gone and the Autobots are starting a new life on Earth. And of course someone stumbles across Xander when he's in his robot form.

The rest of the insanity is up to the poor soul this bunnie decides to adopt.

I came up with a new title for Xander, the Demon's Angel. Born in the mouth of Hell. walked in Hell with impunity and now he walked in the city of...

Horatio Caine was talking to one of his co-workers when an uniformed officer came up to him.

"Excuse me, Lt.," the officer said, "but they need you in interrogation, sir."

Caine removes his sunglasses and looked at the officer. "Do you know why?" he asked.

The officer shook his head. "No, sir," he replied. "I was just told to find you and tell you the message."

Caine slips his sunglasses back on. "Then it looks like I'm heading for interrogation."

Caine walks in to interrogation where Detective Tripp is questioning a young man.

"Frank?" Horatio says simply.

Detective Tripp nods towards a chair before turning back to the young man before him. "I want you to tell Lt Caine here exactly what you told me."

"I've come to confess all of my crimes," the young man said nervously.

"And what crimes are those?" Caine ask.

The young man quickly list off a list of unsolved crimes.

Once the young man was done confessing, Lt. Caine said, "I'm curious. Why are you now confessing to these crimes on your own?'

"The Demon's Angel has come to Miami," the young man stated as he crossed himself. "I thought I could throw myself of the mercy of the court and the church before he came to him to drag me to Hell with him."

"The Demon's Angel?" Caine said.

The young man nods his head. "They say he was born in the mouth of Hell. That he walked in Hell with impunity and now he walks in the street of Miami. They say he's come to collect the wicked and protect the innocent. You might be the protector of Miami, Lt. Caine but even you can not stand up to him. No one can. All anyone can do is pray for mercy."

"Interesting," Caine said with a thoughtful look.

Detective Tripp waves for an uniformed officer to take the young man down to booking and holding.

"What do you think?" Tripp said was the young man was gone. "Vigilante?"

"Possible," Caine said, "but I would like to get more information first."

Horatio, in shock, holds Speed as the younger man is dying. In rush Xander to save the day and Speed's life. In comes the EMS responders to take Speed to the hospital leaving a dazed Caine behind. Xander touches Caine's face to see if Horatio should go to the hospital too for shock, marking Horatio with blood.

As usual Xander slips away when everything claims down since as usual no one can a guy who's like an overgrown puppy as a hero.

Now when Caine snaps out of his shock he wants to know who the person was that save Speed and his involvement in the case so he has his people review the security tapes.

The problem Xander was wearing an amulet that Willow gave him which makes any recorded image of his face blurry so when they review the tape the find a person with a blurry face and maybe 2 glowing green eyes. Have someone in another room laugh evily which is carried through the air ducts to where they're reviewing the tape just as Xander had looked up at the camera... and watch them run!

Of course Horatio's friends are now worry about him since Demon's Angel has now marked him in blood

Tony DiNozzo had a phote of Kate as the 1994 wet t-shirt winner and was teasing her with it. In revenge she email him a photo she had doctored (with or without help) which showed Tony with another man. (Wish I could find that photo)

So I was thinking what if the other man in the photo was Xander (possible a promo photo from when he was stripping) And what if during a case Team Gibbs meet Xander
