UPDATE: OCT 22, 2008This image features all Supergirl costumes that Kara has used. before doing this, I made a simple rule:- It has to be Kara. (altough I broke this rule just once)That because I don't consider any other to actually 'be' Supergirl.The order of appearance is:1. Original version, Action Comics #2522. Action Comics #260 JANSupergirl becomes Super-baby.The following costumes were submitted by fans in the 70s, that why there are so many of them in a very short period of time.3.

There's another one here but not described as 'Kara' so I didn't include her.21. Supergirl One Million.Supergirl #79 - 2003I may have to include another one here.. SG 1000000 uses a different colors, the one here is how she was depicted as Ariella, the daughter of PAD's Linda, the only non-kara Supergirl that I ever like, that's why she's here.22.

Superman/Supergirl:Maelstorm #2 - 200829. Supergirl #??Coming design from Jamal Igle.Note: I included here the animated costumes because when BT and company wanted to introduce Supergirl in the animated series, they wanted the real one: Kara, not the blob of protoplasm named 'Matrix', DC said 'no' so they created a Kara from a planet in the same solar system as Krypton that got destroyed too when Krypton exploded. Her name was initially Kara in-Ze, not a pure kriptonian, not affected by kriptonite (for example) but as time passed, she was slowly transformed into the kriptonian Kara, including her vulnerability to kriptonite. So.. it's Kara.Please report errors or omissions
