Earth is the most powerful of the four Classical Elements in terms of versatility.

I imagine it's 2 slots like usual?

Lexington Kentucky, in the middle of the war (around Dead Beat).

The group consists of a nerdy Wizard, a Knight Of The Cross who is bad at the second part, a werebear, and a a WCV who was switched at birth and you had BETTER BELIEVE I plan on compelling to shit.

We haven't gotten our first arc really going yet but I've set up the groundwork for it. They haven't yet met the Red Court Mafia Boss but they HAVE met the WC. The Wizard, who is a PI, gets hired out every so often by KY's Special Investigations goddess Cassandra "The Black Dog" Black. Recently one of their friends got his ass fried by lightning and eaten by wereanimals, but they dealt with that. Now they have to deal with a sniper that puts the DC Sniper to shame after killing a demon that very much resembles a heavily watered down version of The Operator.

So, I originally planned a case to start out with my team being attacked by Slender Man and they kill him so that the PI in the group can get his paycheck. I took him out at the last minute and then told them about the original opening, only for them to basically beg for me to put him in. So I slapped together a very slipshod version of him with a really common Catch (Blades) because I couldn't remember that "All demons use holy as a Catch". So! I've got an opportunity to bring him back because I claim that only his shell was destroyed and he was weakened by the sorceror using him as a weapon. Lets stat him up!

He is a Demon who can travel through any and all electronics, as well as being able to jump into the Nevernever through them as well, because he was a creature that was created FROM the internet, via people believing the Something Awful thread on top of the typical Slender Man abilities. How should he be statted?

Maybe you could have his coin fused with his sword, as sort of a dark copy of the Swords of the Cross. He could summon it into his hand at any time since it's his coin, which would be a fairly scary trick -- he could walk into a building past security, unarmed, then immediately have a sword in his hand.

What power level are your PCs, and what skill level do their attacks/defenses tend to be at? With that information, I could write some stats...

They currently have 11 Refresh, and they'll either have 12 or 13 by the time the Knight shows up. From what I recall of there stats I have a Knight with Weapons 5, a Wizard  with Conviction/Discipline Great, a Werebear who acts as the Tank offensively, and a WC Vamp who's stats I can't recall but he's fast, has Awareness as his Superb stat, and who I assume can put up a fight since he's a former marine but he hasn't shown off much.

I love the coin idea.

I kinda figured, so its good to have confirmation. I like the thought of a Fallen Sword though. That's more than a little interesting.

As for what I was looking for, Im going for a former Knight who betrayed his bretheren for the promise of power, to show just how dangerous a Knight can be.

So I was playing around with concepts for various villains for my PCs to go up against, including Vampire Mob Bosses, my own take on the Jade and Violet Courts, and a Wizard with Outsider powers related to song, but when I inevitably throw Denarians at my players as requested I wanted to do something new with it, which was when I hit upon an idea. What if a Knight Of The Cross switched teams to work with the Denarians for a reason that I have not yet determined (I have four different candidates for the Fallen Knight).

In my game I house ruled that there were more Crucifixion Swords employed by God's Knights than those made from the nails, with the second set having incorporated the thorns from the Crown Of Thorns. And its been shown that NON-Knights can use the Swords in-canon by Lea and Susan.

My wonder is how I would display this mechanically. My idea was to have his/her Holy Powers be rescinded, give them a Coin, and have them be able to still use their Sword through a loophole in its tenet. Would that work? Are there problems with my line of thinking altogether?
