The Bearded Titan had a bald head, and a long, gray beard stained with blood. In the manga, he was shown to be a heavyset type with a large stomach. In the anime, this Titan was more lean and fit.
After Eren's squad is deployed, an Abnormal Titan appeared and eats Thomas Wagner. Enraged, Eren pursues the Titan only to have his leg bitten off by another Titan. As his teammates are being eaten, Armin could only stand there and watch, paralyzed with fear. The Bearded Titan soon finds Armin, and attempts to eat him. Eren hears Armin's screams, and goes into the Titan's mouth and grabs Armin before he can descend into the Titan's stomach. He tosses Armin to safety, and with what little strength he has left, manages to keep the Titan's mouth open. Unfortunately, before Armin can save Eren, the Titan overpowers him, and closes its mouth, severing one of Eren's arms in the process. Armin watches in horror as the Titan swallows his friend.
While in the Titan's stomach, Eren finds himself surrounded by the remains of several of his comrades, among them one young female soldier who is still dying in the Titan's boiling hot stomach contents. It is during his building horror and desperation at the scene around him that Eren's power to transform into a Titan begins to manifest, and his arm shoots out of the Bearded Titan's mouth. The Titan lumbers for a bit before falling down. Eren's Titan tears its way out of the Bearded Titan's back, and crushes its nape as it walks off, seeking to kill other Titans.
