Plugsuit

The Children in their Plug suits, from the cover of the Carddass Evangelion Special File

A Plug Suit is a form-fitting full body suit, similar to a diver's wet suit, which is worn by Eva pilots in conjunction with their Interface Headsets and aids in synchronization with an Evangelion.

No two Plug suits are alike, as each one apparently is custom-made for its owner's sex, and they have multiple spares of each. A Plug suit appears bulky at first, but activating a mechanism on the wrist shrinks it to being skintight. The Evangelion's number designation is stamped on the top of the chest, and onto a triangular apparatus on the back (except for the suit worn by Kaworu Nagisa, which sported an inverted-divided triangle symbol instead).

Plug suits contain various health monitoring devices to monitor the pilot's condition, as well as medical aid such as built-in defibrillators. Plug suits also have some basic system displays, such as an internal clock that displays how much internal battery power remains in the Eva, located on the back of the hand.

Though the basic form of the Plug suit is unisex (Shinji had no trouble using Asuka's spare plugsuit in Episode 08), male and female plugsuits differ in aesthetic detail. The male Plug suit has a reinforced area around the chest, with two vent-like structures roughly corresponding to the pectorals. The upper chest and shoulders of the male Plug suits are a different color than the lower parts, and the lower torso has a triangular pattering that mimics the abdominal plating of an Evangelion unit. The female Plug suit is more uniform in color, without chest vents or the plating design, though they have stripes on the hips where the male ones have black patches.

There is currently 8 plug suits, 7 for the 00-06 EVA Units plus one for special use. This list follows what material has been released from Gainax, but might change with the introduction of EVA Unit-05 and it's pilot in the Rebuild Series.

Plug suit 00 is the plug suit used by Ayanami Rei for EVA Unit-00. It is distinctive in its white coloring with orange patches at the shoulders.

Plug suit 01 is the plug suit used by Ikari Shinji for EVA Unit-01. The legs and half the torso are in the standard blue color for the male plug suits while the top is white.

Plug suit 02 Follows the standard single color scheme for the female plug suit and is red with a lime green patch on the chest. It is worn by Asuka Langley Soryu for use in EVA Unit-02

Plug suit 03 is worn by Toji Suzuhara for use in EVA Unit-03, with the usual blue color scheme for the legs and half the torso it is followed by a grey top.

Plug suit 04 has no official wearer but is used in EVA Unit-04 by Kensuke Aida in Battle Orchestra. It follows a general yellow color scheme from what has been shown. Note: In Angelic Days it is shown to be in light colors in contrast to the other male plug suits.

Plug suit 05 has no official bearer as of yet but Hikari Horaki has been depicted in it for use in EVA Unit-05. It follows the standard female scheme of one color which is orange accompanied by a red patch on the chest.

Plug suit 06 has no confirmed official wearer, though Kensuke Aida has been depicted in it while piloting EVA Unit-06. The coloring breaks of from the other plug suits in that the usual black patches are white and the red collar is orange. The top is green in color while the bottom area have not been revealed.

Kaworu's Plug suit follows the male color scheme but has a dark purple top. The plug suit isn't made for a specific EVA Unit, but so far it has been used in EVA Unit-02.

Notes

• Plug suits do not appear to be absolutely required to pilot an Eva, as there are a few occasions when Shinji piloted without one. Still, it is stated that a Plug suit increases the pilot's synchronization ratio (its not directly stated how, but it seems to "cut down on interference", etc).

• In Episode 10, Asuka wears a specialized version of her plug suit for the dive into the volcano.
