You're atavistic, a throwback, a primal killer who delights in stalking, butchering and consuming his prey. You have little to no empathy or intelligence; you revel in sadism and your desire to kill is instinctual. You tend to only help those who cause greater harm to others, or because a person's request both amuses you and involves lots of violence. You're simple brain ardently believes that by eating others you are afforded a measure of their power, and so you don't hesitate to eat anyone who seems especially prominent, skilled or formidable.

You love to take drugs; living from moment to moment you enjoy anything that provides more intense sensation. You disdain authority, but not really out of any political feelings, more because authority brings order to the chaos and strife you enjoy. Despite your unsettling and almost alien demeanor people still seem drawn to you, as if curious to stare into the abyss, and you abuse this curiosity to both manipulate and terrifying others. Above all else you are a survivor, and overtime your unnatural longevity and fearsome legend gets you the reputation of being the Bogeyman of the Mojave.

Endurance implants: All except charisma and intelligence.

Lonesome Road boost: Luck, but anything really - I just like even numbers.

Reasoning: A strength of 10 allows for max melee damage, and when combined with Reinforced Spine completely offsets the loss of strength from deadly radiation poisoning. All the rest of the SPECIAL points hit the important marks (AG 8 for Tunnel Runner, EN 8 for Implant GRX, LK and PE of at least 6 for Better Criticals) and were more of less arbitrarily assigned.

Traits: Hot Blooded and Skilled. Hot Blooded has reasonable synergy with Rad Child and a stealth build - when you are discovered and they start to rack up hits you can start dealing more damage in a pinch; it's also a reasonable trait to take to illustrate how easily angered the character can be. Skilled offsets the low intelligence, and whilst Built to Destroy might be slightly more beneficial in the long run taking skilled instead underscores that you should be relying on sneak attack criticals rather than criticals through high critical chance above all else.

Reasoning: Most of the perks here are to optimise damage given any melee weapon through a sneak attack critical, whilst also playing to the fact the character is a drifter (Cowboy and Grunt shows he's lead a varied life). Some perks are taken purely for role-play purposes (Hunter, Terrifying Presence, Bloody Mess and all the cannibal/other creature eating perks), and the order of the perks is chosen to exemplify the build (prioritising the eating perks and Terrifying Presence first at the expense of more practical perks). The character is also supposed to be self-sufficient, hence Implant GRX and Rad Child - they are more or less on top form with or without chems. For Just Lucky I'm Alive, go and kill some Fiends/ghouls prior to level 50 - though Ain't Like That Now is also a nice choice with Super Slam.

Highly desired story perks: Elijah's Ramblings, Reinforced Spine, Lonesome Road, Implant M-5, Meat of Champions.

Use Terrifying Presence whenever possible so long as it doesn't interfere with a quest (the only really instance this applies to is scaring guards around Nelson so you can't do We Are Legion and go on to lead the Khans), especially on the likes of Caesar (by not focussing on unarmed, you don't have to feel bad about the loss of Legion Assault) - try to level up quickly early on so you get the most out of it (you can use it as early as I Fought the Law). Eat powerful enemies fresh, and take remains off others once you have Dine and Dash. Don't be afraid to kill and eat companions too. As I've already mentioned, I'd suggest becoming the leader of the Great Khans given the character's love of chems. Also, enjoy the low intelligence dialogue - from what I've seen it's pretty prevalent.

You can also be horrible on a more intimate level: Making Boone vengeful (which makes him sociopathic assassin with the Indy ending), convincing Lily to stop taking her medication so she becomes a monster, etc.

Having said this, you shouldn't feel the need to do things like wipe out Primm if you don't want to - even a low functioning psychopath can see the advantages of having more traders in the area alive.
