Plugsuit

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

A Plugsuit is a form-fitting full body suit, somewhat 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 plugsuits are alike, as each one apparently is custom-made for its owner's sex, and they have multiple spares of each. A plugsuit 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).

Plugsuits contain various health monitoring devices to monitor the pilot's condition, as well as medical aid such as built-in defibrillators. Plugsuits 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 plugsuit is unisex (Shinji had no trouble using Asuka's spare plugsuit in Episode 08), male and female plugsuits differ in aesthetic detail. The male plugsuit 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 plugsuits 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 plugsuit 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 are currently 8 plug suits, 7 for Eva-00 to Eva-06 plus one for special use. This list follows what material has been released from Gainax, but might change with the introduction of Eva-05 and it's pilot in the Rebuild Series.

Plug suit 00 is the plug suit used by Ayanami Rei for Eva-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-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-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-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-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-02.

Notes

• Plugsuits 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 plugsuit 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 plugsuit for the dive into the volcano.
