In SlashTHEM, a female Ninja is called a Kunoichi, e.g. on the base attributes display.
In NetHack, "Ninja" and "Kunoichi" are the male and female rank titles of a Samurai from experience levels 6 to 9. In SLASH'EM Extended the male title is changed to Ninja Gaiden; the female title remains Kunoichi. In SlashTHEM, the equivalent rank title is "Kumigashira" (which translates roughly to "squad leader").
The Slash'EM Extended version of the role has access to a wide range of skills:
SLASHTHEM gives the Ninja a skill set reminiscent of both the Rogue and Samurai:
- Slash'EM Extended u_init.c line 3956
- SLASHTHEM u_init.c line 2081 in v. 0.8
Ninja gain these techniques in SLASHTHEM:
SLASHTHEM tech.c 152
In SLASHTHEM, Ninja gain searching instead of invisibility at XL 3. They continue to gain additional abilities:
SLASHTHEM attrib.c line 71
- A blessed +0 wakizashi (short sword)
- 9 shuriken
- An uncursed potion of sickness
- A blessed potion of invisibility
- An osaku (lock pick)
- +1 leather cloak (SlashTHEM)
- +1 low boots (SlashTHEM)
- A +0 kaginawa (grappling hook) (SlashTHEM)
The SlashTHEM Ninja will know the starting shuriken as "hira-shuriken" (flat shuriken), as part of an expanded list of Japanese item names. This reflects the fact that the term "shuriken" was historically also used to refer to other thrown (and sometimes wielded) weapons, not only the star-shaped projectiles associated with the term in Western culture. Darts are known as "bo-shuriken" (stick shuriken).

- XL 10-13: Rokkyu
- XL 14-17: Gokyu
- XL 18-21: Yonkyu

SLASHTHEM gives the Ninja a new quest artifact, Fuma-itto no Ken, a chaotic ninja-to (broadsword) which adds +8 to-hit and +8 to damage, grants drain resistance while carried, and can be invoked to create a stack of hira-shuriken. This weapon was adapted from an artifact of the same name from dNetHack.

Two early versions of NetHack contained "Ninja" roles. Regular NetHack contained a Ninja role from versions 1.3d to 2.3e, which was replaced in 3.0.0 by the Rogue role, making it a defunct feature. NetHack-- 3.0.10, a variant of version 3.0.10, and a precursor of SLASH'EM, included a revived Ninja role in addition to the Rogue role. The vanilla Ninja had a much simpler inventory than the current role, consisting of a katana, +1 leather armor, and up to 25 shuriken. NetHack-- gave the Ninja the wakizashi, potions of sickness and invisibility, lockpick, and intrinsic stealth that are associated with the role in Slash'EM Extended and SlashTHEM, so it seems that the current incarnation of the role is based primarily on the NetHack-- version.
The NetHack-- Ninja was one of nine new roles in that variant, in addition to the twelve in the contemporary version of NetHack. The discussion thread in which the authors first announced the variant suggests that some of the new roles were taken from a list proposing a role for every letter of the alphabet. See here for the relevant post.
After the release of NetHack 3.1.3 in 1993, NetHack-- was updated to NetHack-- 3.1.3 by porting some of the changes from NetHack-- 3.0.10 into a patch for the newest version. Due to some changes in the vanilla code, however, some content was removed to improve compatibility with NetHack. Most significantly, NetHack 3.1 had seen the addition of the Quest branch. To avoid the challenge of fitting full-length quests for the roles that had been added in NetHack-- 3.0.10 into the patch code, those roles were simply left out of the patch.
The Ninja role, along with the other eight new roles in NetHack-- 3.0.10, made its reappearance in the variant Slash'EM Extended. It was also carried over, with some tweaks, into SlashTHEM, a variant of Slash'EM Extended v75.
