Toji is a tough boy, the stereotypical "jock," and is in constant conflict with Asuka. His younger sister was injured in the battle between the third Angel, Sachiel, and Unit 01, and he beats Shinji up soon after for being indirectly responsible. However, after witnessing firsthand the suffering Shinji experiences piloting Unit 01 in the battle against Shamshel, Toji comes to respect Shinji and the two eventually become friends.

Toji Suzuhara is the Fourth Child.

Toji's Eva, Unit 03, is taken over by the thirteenth Angel, Bardiel, and is eventually destroyed by Unit 01, which was under the control of the Dummy Plug system. He is severely injured when his Entry Plug is crushed; in the manga, he is killed.

In 3.0+1.0 of the rebuild series, he is a doctor residing in Village 3 and is married to Hikari Horaki, with a daughter.

_Toji is named after one of the main characters in the novel The Fascism of Love and Fantasy (Ai to Gensou no Fascism) by Ryu Murakami._
