Arguably the most famous Evangelion unit, EVA-01 has a predominantly purple body with neon green highlights, yellowish eyes and a characteristic single horn that distinguishes it from the other EVAs. Designed in real life by Yamashita Ikuto during the 90s.
It has the hidden ability to go berserk, in which case its eyes glow red and a large mouth opens itself from the Evangelion's faceplate. In Evangelion: 2.0 You Can (Not) Advance, the unit undergoes a process called "Pseudo-Evolution" after devouring Zeruel, where its green highlights become red and a shining halo materialises around the horn. In this form, the unit's left arm may or may not be a glowing construct.
In the original series it is revealed that Ikari Yui's essence fused with the mecha during a pilot test, turning it into Shinji's actual mother.
