Sulik

Sulik is a joinable NPC in Fallout 2.

Not much is known about Sulik, apart from what little he tells to the Chosen One. From what we do know he is from a primitive village located somewhere by the sea, and has come in search of his sister who he thought was captured by slavers. At the beginning, Sulik requests that the Chosen One help him find his beloved sister, but unfortunately neither of them ever pick up a lead past the slaver Metzger. Sulik prefers to fight with a Sledgehammer, but (even if he doesn't know it) is much better with a famed .223 pistol. He is even better with it once he is levelled up to the maximum, having 12 Action points (highest of all the recruitable NPCs that can use a Firearm), and will fire 2 shots per turn continuously, even after reloading.

Sulik said that his "sis gone trading another village and never come back". Upon further questioning, he divulged that when he investigated, he found "One survivor. Dude was in bad shape. Said evil warriors with magic torches came. Fire would lick tribe warriors and they'd go to the spirit. [...] The evil warriors tied up the rest and took off. Sis with 'em. Fren, we be find her or dying trying." The description is remarkably similar to that of Hakunin's upon the assault on Arroyo by Enclave soldiers. It is possible that this village was raided by the Enclave as well, snatching captives for experimentation with the toxinizied FEV.

As a side note, 'Grampy Bone', the huge bone through his nose is connected to the tribal lore of his family and village; through it he is able to speak to his grandfather and other important dead spirits of his tribe, who give him advice (on inhabited areas only).

Sulik returned to the primitive tribe for a few moons (months) after breaking paths with the Chosen One, then headed east in search of his sister.

Making Sulik join
You can make Sulik join your team, even if you are playing an Intelligence 3, or even 1 character. At first, he will make fun of you, talk about a big hole in your head, but then he will join. Just experiment with different dialogue combinations. Note you must have 350$ on you when you do as you only get one shot at recruiting him through the dialogue combinations. Also of note Sulik makes a poor recruit for low intelligence characters due communication problems. ie you cannot order him to wait or put away his weapon through dialogue.

Sulik will attack you if you decide to become apart of the slavers guild.

You can sell Sulik to Slavers Guild in Den for 1200$.
