Yes, it is extremely easy for a character with Indomitable to surgically take out a single opponent.  I agree the resulting player fiat can be kind of annoying; I find it deflates tension and makes scenes flatter.  But if you follow the fiction and make things real, you'll move the game away from easy kills into more dangerous territory.  The Indomitable's reputation will precede her.  Smart leaders will use cannon fodder and feints.  Smart lieutenants will goad their leaders into attacking the Indomitable so that she can do their dirty work of regicide for them.  People will become frightened, and refuse to deal with her, and suddenly resources will dry up.  You can't eat fear. 

My favorite thing to do to an Indomitable is take aim at the things and people they love, when she's not right there to save them.  Where's you called shots now, Clarity?  Huh?  HUH?  (Sorry, flashback to my last game.)

And there's always setting the players at each other's throats.  Indomitability does not work against PCs.

A few things that have come up in my games:

1) The Ghoul was made up of pieces of bodies.  She literally had the Ghost's heart, which perhps explained their budding romance.  If this had been an ongoing game instead of a one-shot, the Ghost's desire to watch over his kid brother would have intersected nicely with the Ghoul's Dr. Frankenstein-ish father's desire to build her a sibling.

2) The Witch's see-through-their-eyes spell goes badly, and he winds up switching bodies instead of just peeping.  Much of the session was driven by multiple body switches.  Stupid hexes.

3) A different Witch tries to bind the Werewolf who's hulking out at the prom.  And does!  But all that animalistic energy has to go somewhere, and suddenly the dance turns into an orgy of sex and violence.

I let characters narrate some outcomes, especially if the outcome is very definite: the PC very much got the local doc into the sack, very much killed the local doc, etc.  Rather than narrating yet another NPC death (or seduction), I hand it over to the player to say how it happened.  It gives them a chance to detail what their character is about.  It's meaningful if Wembley dodges and weaves and dances about before landing the perfect blow, vs. leaping on the doc with a scream and beating his skull into paste.  It's meaningful if Wembley engages in a playful romp and some pillow talk, instead of just dropping trou and squeezing his eyes shut until the doc is done.

In the afterglow of GenCon, I realize that I did not get to meet Pheylorn.  Sadness.

I hope you (and any other attendees) had as good a time as I did!

It's a little more work, but it might be fun to use what you have as a framework for character-specific custom love letters.  Switch up the pick list and maybe even the stat.  You can also have them point to E.g., an Angel might have roll+Sharp, and pick from:

* You've heard this hold does a good business in medical supplies.  If you go looking to restock, you get twice what you pay for.
* Unfortunately, the reason there's so much supply around is that nobody knows how to use it right, and everybody's *really* excited the hold has a new Angel.

The Hoard in my current game is Betty Draper from Mad Men at her most petulant.  She wants what she wants, feels constantly put upon, and takes every opportunity to lash out at people who make her unhappy.  And, oh, the jealousy.

Her Hoarder treats her like a girlfriend who has to be constantly managed.  We've learned in play that the Hoarder let his wife die rather than risk his Hoard.  Now the Hoarder and the Brainer are in a relationship, and the Hoard is trying her damnedest to get him to kill and stuff her so she will always be there, but silently and under control.  She even offered him taxidermy eyes that looked just like his wife's.

The Hoard also has some times to the Maelstrom, though she prefers to keep quiet and out of the way of the greater powers that roam that trash heap.

Brainers are good at convincing people to just hand stuff over.

Brainers are good at convincing people to forget something and leave it behind.

In the settings I've played, just about anybody can shoot somebody else, but not many people can dig into your brain.  So muscle is cheap and plentiful, but pet psychics are not.

Hunting pack.  They're really good at moving through the jungle canopy, and one of them has a net.

This is really neat.  I may start using it tonight for my ongoing game.

One question: the countdown clocks normally start at 0 and get worsse as they head towards 12.  Why did you chose to flip it?

Along with the mechanical aspect, moves like Leadership change the color of the game.  In my experience, players take certain playbooks or moves not because they want more tools to deal with a specific situation, but because they want to bring that situation into play, or focus more on it.  They don't take leadership because they're tired of manipulating or going aggro on their ersatz gang, they take it because they want to make leading more of a thing.  It's a flag to the MC and other players to give more of a thing, like a Key or Aspect.

I tried to sign up for your game. Man, those slots went quick!

Yay!  A player!  I was worried.  Would you like to play a Skinner?  They're the best!

In a more serious vein, I'm pondering if I want to try and do a scenario a la Hatchet City, or just do typical first session, follow the characters sort of thing.  I kind of like the latter, but I worry about the PCs not jelling well.  I wonder if it would help things along to have somebody pick one of the "queen bee" playbooks (Chopper, Hardholder, Operator, Hocus, Maestro'D), and have the other PCs be part of the "team".

(My favorite set-up is a Maestro'D and their staff.  Because Maestro'D's are the second best.)

I do!  Though, really, everyone should just play Skinners.  They're the best.  One of them can even be in a mask.  Oh, dear, now I'm imagining a bordello specializing in roleplay.  "Here comes Rolfball, someone tell Jujube to break out the Brainer outfit." 

I plan on running games at GoD, with AW one of the options. 

I would ask him why he wants to play the character as an inhuman monster out to get the other PCs from the get-go.  What does he hope to get out of that approach?

If the other players were really mean, they'd use the first session to establish themselves as loyal followers of the Hocus.
