When Tabris arrived at he became Shinji's friend and the best synch-rated pilot. Soon after he began his attack. His synch-rate was so high, he could pilot without getting into the entry plug. With Eva-02 as his bodyguard he made his way to the heart of NERV. While enraged Shinji Ikari went after Eva-02, Tabris realized that he had been duped by SEELE when he saw the white giant pinned to the cross above the lake of LCL.
Profile: The seventeenth Angel was the least expected. Keel Lorenz was the only one to know that Kaworu Nagisa (born on the very day of the Second Impact and the Fifth Children) was indeed the final messenger of man's fate. Lorenz sent Tabris to NERV headquarters in order to hurry the prophecy of the Dead Sea Scrolls along.
Fate: When Tabris realized that the Angel that he was face to face with was Lilith and not Adam (the one whom all Angels must return) he allowed Shinji to grab him with Eva-01. He explained that he would allow himself to die so that mankind could decide for itself the path that must be chosen. After 60 seconds of pause, Shinji squeezed and Tabris/Kaworu died.
Notes: Tabris is the patron Angel of Free Will.
