This first transformation is not a heroic triumph but a chaotic, terrifying mystery:

Inside the Titan's stomach, surrounded by the carnage of other devoured soldiers, Eren refuses to accept his death.

He reaches out his hand and bites his own hand (a trigger mechanism he would use later), screaming: when does eren first transform

This first transformation is not a heroic triumph
