Unit 15

Unit 15 (Juu gogōki:じゅう ごごき) It houses the soul of Link's mother which is unnamed. It is believed to be the sister of the Evangelion Unit 01 and Evangelion Unit 14. So if that rumor is true that will make the unit 15 the third eva to be born from Lilith. The unit 15 has a angelic mode which can draw parallels to the unit 01's beserker mode. Which means that this eva is also capable to go without a umbilical cable, but so can the mass production evangelions later on.

Overview
Created in the Third Annex of Gehirn's Artificial Evolution Laboratory in Hakone from 2004 to 2005 and deemed a functional Eva unit in 2015, Unit 15 is piloted by Heero Twilight (with Ruto Sea as a backup pilot), and has one of the best battle records of all the other Evangelions, because of the Unit 15 always fighting battles meant for the Unit 14. The angelic mode function of the Unit 15 is believed to give the Unit 15 six angel wings with a unknown purpose, a halo which may serve as connection to Adam, gains high speed regeneration abilites, and a mysterious ability to teleport and use god forms of its progressive equipment. The Evangelion only seems to go to great leaps to protect its pilot and in some battles its backup pilot. The Evangelion's resident soul, Link's unnamed mother is responsible for such actions. Unit 15 is called the " Sub-Test Type", perhaps because of the experimental way in which it was created: although Unit 15 seems to be an Adam-derived cybernetic organism like all other Evangelions, it is the other Eva to have been born from Lilith.

Unit 15's armor is primarily grayish black; some components are colored white on the head, chest, abdomen, legs, and arms, and some components are colored red, green, or orange. The helmet, with its prominent horn and "frill," is vaguely evocative of a ceratopsid dinosaur. The pectoral plates are different from those seen on any other Eva. The humanoid entity beneath the armor has light brown skin, two emerald-green eyes, four small nostrils positioned preorbitally, and red blood.
