Inner Sphere analysts were stumped trying to determine the purpose of the second-line BattleMech they assigned the code name Vixen after sighting it among the garrison forces of Clan Jade Falcon. The Incubus, as it is known among the Clans, is somewhat expensive for a light garrison 'Mech, which confused Spheroid observers until they understood how important one-on-one duels were in Clan culture and how often they occurred among bored garrison troops. The Incubus is a 'Mech that is often used in such Trials, especially because it is easy to turn off weapons to effectively balance the 'Mech's strength with that of an augmented Elemental. Despite its purpose, the Incubus does show up in some second-line forces as well and is highly regarded in all roles it serves.[5][6][7][8]

Following Clan Hell's Horses recapture of Tokasha MechWorks Alpha, and inspired by Clan Diamond Shark's "Phoenix" renovation of older designs, the Hell's Horses developed a new version of the venerable design incorporating newer weapons technology to expand their BattleMech strength. Though visually different, the core purpose of the 'Mech remains intact, especially useful given the Horses Elemental-heavy touman. This visually refreshed Incubus also appealed to Clan Ice Hellion, who developed their own variant of it, examples of which fell into the hands of Clans Cloud Cobra and Star Adder following the Hellion's ill-fated trade mission to Tanis prior to the Wars of Reaving.[8]

Weapons and Equipment[edit]

Part of the Inner Sphere observers' confusion around the garrison role of the Incubus is its use of an expensive 270-rated XL engine, endo steel frame, and five and a half tons of ferro-fibrous armor. While seemingly expensive for a "mere" garrison 'Mech, this gives the Incubus impressive performance for a light 'Mech, as well as an aggressive profile despite its weight, a distinct psychological advantage for its pilots.[5][6][7]

The Incubus is armed with primarily medium-range weaponry. A large pulse laser is accurate and covers a respectable range, mounted in a semi-modular "rifle" in the standard version's right arm. Similar to such classic designs as the Wolverine and BattleMaster, the "rifle" placement makes both repair and modification of this weapon extremely easy and rapid.[5][6][7] The Hell's Horses upgraded version replaces the "rifle" with a forearm mounted pod instead, but retains the same semi-modular nature for this reason.[8]

The arm-mounted primary weapon is supported by over the shoulder light weapons clusters in each side torso. A pair of ER medium lasers are solid backup weapons, while four machine guns are highly effective against unarmored infantry. A half ton of machine gun ammunition and 10 double heat sinks are more than adequate for Clan Trials.[5][6][7]


  • Incubus
    Clan Hell's Horses Incubus 4 completely changes the weapon loadout with an eye to lower cost, but keeps the core purpose of the 'Mech intact. It mounts a heavy large laser, two medium pulse lasers, two micro pulse lasers, and two ER micro lasers. It can quickly build up heat in normal combat situations, but most of the Trials it is involved in necessitate disabling multiple weapons, so this is rarely a problem. BV (1.0) = 1,215, BV (2.0) = 1,581[11]
  • Incubus
    Clan Ice Hellion, always prolific users of fast light 'Mechs, copied the original redesign of the Incubus, but decided to create their own variant. This fifth version mounts an ATM-6 with two tons of ammunition, two ER medium lasers, and four light machine guns. BV (1.0) = 1,239, BV (2.0) = 1,364[12]
  • Incubus
    This variant replaces the large pulse laser with a UAC/2 and one ton of ammo. The significant loss of damage capability makes this decision questionable. BV (2.0) = 1,175[1]
  • Incubus
    Identical to the standard model, the 8 merely swaps out the large pulse laser for an LRM-20 and one ton of ammo. These are both mounted in the right arm. BV (2.0) = 1,557[1][15]

  • The Incubus/Vixen as originally depicted in the Jade Falcon Sourcebook and the original Technical Readout: 3055 was constructed via Fractional Accounting, allowing it to carry a fifth machine gun in the head, removed under the current construction system starting with Technical Readout: 3055 Revised.
  • In German products, the unit's proper Clan name was left unchanged. The unit's proper Inner Sphere name was translated to Füchsin.
