The "Jumping Titan" was a Titan that attacked Eren Jaeger's squad and ate Thomas Wagner.
The Titan was very tall and slim, with an outstanding rib cage, and had long, blond hair.
After Eren's squad is deployed, the Titan jumps out and crushes Thomas Wagner's hips in its mouth, then eats him moments later. Later on, the Titan is killed by Eren in his Titan form.
