(Up, Down, Strange, Charmed, Top, Bottom- Up and Down quarks form normal matter, the other four are much rarer and have been generated only in particle accelerators so far). On the concrete walls, different states of quantum particle spin and different quark names are painted. It is noted by Shinji Ikari as being remarkably similar to Rei's apartment, and Ritsuko makes it clear that the room certainly has made it's mark on Rei's subconscious. Rei's birthplace in Central Dogma is also shown in Episode 23. These clones are the origin of Rei's 'If I die, I can be replaced' statement from Episode 19. The Dummy System in Eva-01 also shows the name REI on it's side when it is activated during Episode 18. These are referred to by Ritsuko Akagi as being 'spare parts' for the Dummy Plug system. In Terminal Dogma, a large tank full of spare Rei clones is maintained. Since Rei was created after Yui died and none of her bodies can possibly be 14 years old, it's implicit that Gendo and Fuyutsuki can manipulate her growth. She is later seen in 2015 apparently aged 14 (she would have to appear the same age as Shinji's classmates since they are in the same class). Seen in 2010, she has the physical appearance of a small child, perhaps around four or five years old. Rei Ayanami was created sometime between 20, as suggested by her appearance in Episode 21.

On some level, Rei Ayanami may incorporate DNA from the Second Angel, Lilith, because she is the vessel for Lilith's soul. Rei Ayanami was the product of Gendo Ikari and Kozo Fuyutsuki attempt to retrieve Yui Ikari from Eva-01 using her salvaged remains. Main articles: Episode 21, Episode 22, Episode 23
