Pelosus-pattern energy sword

The Pelosus-pattern fireblade, more commonly known as the energy sword, is a Covenant melee weapon manufactured by Assembly Forges.

Design details
The Pelosus-pattern fireblade is one of the many energy sword variants manufactured by the Covenant. The Pelosus-pattern is characterized by its circular blade contour around the hilt. Some Pelosus-pattern energy swords contain a fail-safe mechanism that can permanently disable the weapon if the Sangheili wielding it drops it. When dropped, the failsafe engages by deactivating the magnetic field before dispersing the plasma. The plasma then consumes the handle and thus destroys the weapon.

Usage
The Pelosus-pattern fireblade is a weapon carried by high-ranking Sangheili; during the Battle of Installation 04 and the Battle of Installation 05, it saw extensive use among Ultras, Zealots, Stealth Sangheili, Sangheili Special Operations Officers, and Honor Guards. During the Algolis Invasion, the Sangheili Itho 'Hesiikee was a known wielder of a Pelosus-pattern bloodblade, which he intended to use to execute the Jiralhanae Atriox, but he was killed by his own bloodblade when Atriox retaliated.

Variants

 * Bloodblade - As with many other patterns of energy swords, the Pelosus-pattern energy sword can be customized as a bloodblade, with red-colored plasma.

Gameplay
The Pelosus-pattern energy sword was first introduced Halo: Combat Evolved, albeit unusable by players. It was then made available to players in Halo 2 and the Halo 2: Anniversary multiplayer component in Halo: The Master Chief Collection. The energy sword is a powerful melee weapon in close-quarters combat, capable of killing most foes with a single strike. It is a power weapon that appears on some multiplayer maps. In Halo 2: Anniversary multiplayer, the bloodblade variant is held by infected players in Infection.

Production notes

 * In the remastered graphics of the Halo: Combat Evolved Anniversary and the Halo 2: Anniversary campaign, the in-game model of the Pelosus-pattern energy sword was replaced by the energy sword from Halo: Reach. However, the remastered Halo 2: Anniversary cinematics still depicted the Pelosus-pattern energy sword.
 * In the Halo E3 2000 trailer, John-117 was shown using the energy sword. In the final release, the energy sword is not available to players.
 * The Fable II: Limited Edition comes with "Hal's Sword", a crystal blade shaped like a Pelosus-pattern energy sword for in-game use, to coincide with the use of "Hal's Armor", which resembles the MJOLNIR armor.
