Evangelion Provisional Unit-05

Evangelion Provisional Unit-05 (仮設5号機) is one of the new Evangelion units introduced in Rebuild of Evangelion, making its first appearance in the second movie, Evangelion: 2.0 You Can (Not) Advance.

Profile
Evangelion Provisional Unit-05 (封印監視特化型限定兵器 人造人間エヴァンゲリオン 局地仕様仮設5号機) is the first Evangelion unit which is not built with a humanoid-like appearance, like Units 00–03. This could however be due to the fact that this unit wasn't fully completed during its first deployment, as its name suggests. It is kept at Bethany Base to guard the sealed Third Angel and eventually recapture or destroy it, should the Angel escape.

Its upper body is fairly similar to the other Production Model Evangelions with its V-shaped torso armor with its head bearing a conical helmet with a glowing yellow visor. However the unit has completely mechanical limbs, the left one being a claw and its right one is initally seen mounting a fixed spear, but Mari later reveal that it is also a claw. Its shoulder pylons are also different from the other production models. It has energy permanently supplied thanks to a pantograph system installed on the shoulders pylons of the Evangelion and is connected to a large catenary network on the ceiling of the corridors of Bethany Base. Each shoulder pylon energy system is called 1st Current Collector and 2nd Current Collector in the display screen. In each pylon, where it would have a place for a weapon, there are two light sources that shines when the Evangelion is activated. Therefore, Unit-05 does not have a socket for connecting an umbilical cable. The back of the Eva is quite exceptional.

Its lower body is entirely made of prosthesis, with its limbs being four appendages each equipped with a cogwheel at their end. To facilitate movement and breaking, there are two drills that are protected by a cover that when liberated can drill into the ground and secure movement. Each drill also possess a three point laser in its tip to help the aiming of it. The axis of the four lower limbs can be changed to any direction when the drills are in use. These appendages are also equipped with 2 thrusters each to move beyond the Styx shaft in the Bethany Base, allowing it to ascend vertically.

Provisional Unit-05 has a light grey and green color scheme, with some glowing yellow details throughout its body. It should be noted that the green color scheme seems to be only present on the prosthetic limbs and the light grey on the biological parts.

Features
Provisional Unit-05 has an extremely limited array of weapons (as suggested by its full designation) in that it has only one weapon: the Anti-Angel Extermination Weapon Spear of Longinus Basic Type (Pseudo-Restoration) (対使徒専用殲滅兵器　簡易式ロンギヌスの槍 (似非復元型)). It is a melee-only weapon with a glowing gem near its tip which is able to pierce an A.T. Field as one can observed during its fight against the Third Angel. Because of its unique configuration, this Evangelion can't use the standard Evangelion weaponry.

Due to the Evangelion's urgent use, the pilot is required to wear special equipment with tubes attached to the wrists and a large helmet with some faulty calibrations due to being forcefully sychronized, not even being able to use the claws to full power.

Another noticeable difference is that it lacks an umbilical cord. Instead it gathers its energy from pantograph-like wires atop the shoulder pylons, which connect to the roofs of the Styx shaft of Bethany Base, operated similarly to a trolleybus.

As the internal power is beginning to come to an end. The Unit-05 head opens its mouth, revealing its mouth, with six pairs of teeth in its upper and lower jaw.

As the core of the Third Angel is destroyed, the entry plug containing Mari is ejected from the Evangelion body and put on a jet airplane that is able to escape the explosion of the Evangelion main body. It isn't shown what happens to the airplane, just the entry plug floating in the water.

Evangelion: 2.0 You Can (Not) Advance
Unit-05 is piloted by Mari Makinami Illustrious during the opening scene of the movie, It is deployed to counter the escape of the captured Third Angel which was being held at the European/Russian Bethany NERV base. The Evangelion uses all the functions of this configuration like the cogwheels, thrusters, claws and the spear to combat against the Angel. Before the internal power runs out, Mari manages to crush the core and escape as the Evangelion explodes leaving the usual rainbow. Soon after, the Angel also explodes into the Cross shaped and halo, leaving two crosses near each other. The entry plug is seen floating in the water and Mari emerges from it, thankful of being alive as she praises Unit-05 and also saying goodbye to it.

Evangelion: 3.0+1.0 Thrice Upon A Time
Unit-05 makes it's last onscreen appearance when Gendo destroys all of the Evangelion Units with the Spear of Gaius piercing Unit-01 and Evangelion 13 to remove everything related to Evangelion.

Development
The design seen in the preview of Evangelion 2.0 at the end of Evangelion: 1.0 You Are (Not) Alone is a little bit different of the final design in that it has a slightly different color scheme as well as a second spear in place of the left claw of the final design. The particular classification of the unit, "Provisional Unit", was decided from the first script and remaineg unchanged since

In this 2007 rough design done by Ikuto Yamashita, the upper body is similar to the final design, but still using two legs. The arms protections acts as the claws and it holds the spear with the humanoid hands.

In a later design, the body is stockier than the previous design, having more elements of the final designs like the four limbs, but still with multiple differences like the rocket container shoulder pylons and a different head design.

This design was used in the preview of 2.0, having similar color schemes, but wielding two different shaped lances and a simplified lower system than the final design. The design was later altered once again with new additions to it.
