Riddick has had a long life. He has fulfilled the prophecy and has leaded the Necromonger to their destiny. And now as Riddick approaches his next great adventure, he's soul is stolen by the Power That Be.

After forming a new body for Riddick, the Power That Be inform that him that they have a job for him and if he completes the job then when he dies the next time he will be allowed to pass on. But if he does not complete the job for them then the consequence will be unpleasant.

The job is rather simple, Riddick needs to kill the Slayer's White Knight, kill Xander Harris.

Of course the Power That Be have forgotten a number of important things like Xander is very hard to kill and that Riddick follows his own rules and not someone else.

So while the Power That Be plot the next course of action for after Xander's untimely death the higher Gods make beats on how long the Power That Be will live before Xander and Riddick come after them

Xander as a good Person & Grimm thanks to the positive influence/support of a family of open-minded Jagarbar's AKA The McNally Family who were murdered pre series by his Grimm grandfather and who he accidently killed in return unknowingly setting off the Grimm family legacy. Ends up becoming a strong protector of innocent Wesen and Humans without the knowledge of Angel, Buffy, Giles or Willow who thanks to his natural and accurate profiling abilities was/is never as close to them as on the show, leading to a bigger gap between them all a lot sooner.

Finds out he has possible relative/s {e.g. Sean Renard(half brother) &/or Nick Burkhardt(cousin)} who are not abusive, alcoholics or serial killers and either goes searching or they find/rescue him.

Challenge

= Xander is de-aged & possibly sent across realms to become the son of BAMF teen Stiles Stilinski and maybe a stalker/roofies 

= Stiles has secretly been training in self defence, weapons, magic, first aid, investigation techniques, profiling, hacking & the supernatural thanks to what been happening as he doesn't want to be a victim. 

= After getting custody of baby Xander takes a hard look at his life, friends, allies, himself and his priorities

= Ends up being less inclinded to help/lie/backup bad friend Scott & the Hale Pack unless truly necessary.

= Becomes very anti Argent family

= Doesn't tolerate anyone BS &/or Manipulations in any shape or form against him, his dad or innocents

When you're addicted to something you'll do almost pay any price, do anything for your next hit.

When the Powers That Be realize that Willow has become addicted to Dark Magic they realized they had the perfect opportunity to kill off two birds with one stone.

The plan was simple; they would give Willow a chance to get a really good hit of magic in exchange for doing a spell. The agent to the PTB told Willow the spell was to protect a loved one when in reality the spell would send Xander out of the realm that the PTB ruled, never to return.

The agent supplied Willow the items she need for the spells which are thing that Xander had lost, were stolen or Anya had sold.

The PTB were not interested in whether or not if Xander survived wherever he was sent, just so he was forever out of their way. The rulers of whatever realm he arrived in can do whatever they want to him.

The magic hit the PTB will supply will be too much for Willow to handle and will either burn out her magic pathways so that she will never be able to use magic again or kill her.

The realm that Xander ends up in will be the author who takes this fic.

(Yeah I know it's not much of a fic but it's a good set up for a crossover in which you don't' want to involve magic later on. Possible crossover includes the Charmed Ones, StarGate SG-1 or Riddick's universe (Pitch Black) I just think that people don't use Willow's addiction to the full potential.)

On Halloween, Xander loses a bet and has to dress as a Octopus-like costume. Instead of a Squid, he turns into an Ascended Ancient version of himself. While he is transforming into his costume, his costume needed extra Energy to finish the transformation, so it absorbs the "endless" Energy of the Hellmouth, and because it has links to all of the other Hellmouths around the World he ends up absorbing those too, making him a literal Ascended Hellmouth.

Requirements:
-Because Xander tranformed into an Ascended on his own(the way he subconsiously absorbed the Hellmouth energies to complete the transformation under his own power, even if did do it unconsiously/subconsiously), the Ascended Ancients/Alterans can't get involved with him, I mean they can get involved with him but not in the "You can't use your powers in the lower planes to help(etc...)" and their whole "non-interference" policy, because he wasn't technically Ascended by them. Basically, he can start his own Ascended Group, with it's own rules and regulations.

-There -have- to be real Gods and Goddesses, not just Ascended Ancients/Alterans pretending to be them, like the Ascended Ancient/Alteran Janus.

-The Powers that Be have to be fakes, they only want balance because it keeps them in charge. If there is only balance and neither good or evil can win, then they can still be in charge.

-When Xander gets Ascended because of the costume he gets the status of an Elder God

-When Xander interferes on the Hellmouth, it's only as a last result, otherwise he would be just as evil as the bad guys, what with not letting them get fulfullment for a job well done, or, Xander could have made a clone of himself and set it loose in Sunnydale that has his memories up until he transforms into his costume and he just alters their memories so that things contunie like they did in the series only with an occasional help here and there, while he's elsewhere in the Galaxy, getting things ready for the SGC.

-(A) Xander has to secretly go back in time to when they were setting up the constituion of the U.S. and have them make the SGC officially independent from the US Governent in his time, and its own unlimited funding, etc..., that he won't let anyone know about until when they(The N.I.D. through Kinsey) try to excert their "supposed" authority over SGC. And everything from Cheyanne(?) Mountain, all the way too the Antartica Outpost. Or, he can have the Founders of the U.S. make an independent section of the U.S. Government totally dedicated to Aliens, like England had the Watcher's Council there for Magic. George Washington could have even been an Ex-Watcher if you want him to be, and he could have even put it somewhere in the Decleration or Constition about a Slayer getting the highest clearence level possible, and diplimatic immunity.

-Because of the nature of the Hellmouth, Xanders power is literally endless, he gets the memories and knowledge of anyone and everyone who has ever been in contact with a Hellmouth, and when one is destroyed, he gets/absorbs that endless amount of energy

-For anyone who wants to put Dawn in, they have to have her an Ascended Key, even if she did unconsiously pick a Green Octopus costume that matchs the Green color of the Key.

-Xander and Dawn, -have- to have their own dimension/plane of existence/realm/etc..., that is protected from any and all threats, kinda like a safe haven like the Elders realm is/was in Charmed.

-Any number of crossovers you want.
