Pieck Finger

The Yonsoku hokō-gata no Kyojin (四足歩行型の巨人) is an intelligent Titan acting as a scout and mule in Zeke Yeager's army.

Appearance
When standing on all fours, this Titan is tall and walks on all four limbs in a quadrupedal fashion as its name implies. Its torso is long and flat, allowing for materials to be easily packed onto its back. Its face is elongated, bearing wide lips and a large nose with a very small forehead and a huge mouth.

Return to Shiganshina arc
After Zeke and his army appear, the Quadrupedal Titan is seen walking among them, acting as a mule by carrying crates and barrels strapped to its back. When Erwin Smith sees this, he theorizes that this Titan has intelligence and acted as a scout to warn Reiner Braun of the Survey Corps' oncoming approach.

Erwin's theory was correct. The Quadrupedal Titan had been watching the Survey Corps' movement toward Shiganshina District. As Zeke was conversing with Reiner and Bertolt Hoover, the Titan spoke, warning them of the Survey Corps' imminent arrival. After the battle with the Survey Corps begins, the Quadrupedal Titan assists Zeke by supplying him with rocks to crush and throw at the soldiers.

After Zeke slaughters most of the Survey Corps in their final charge, Levi Ackerman brutally rips apart Zeke's Titan and removes him from the nape, preparing to feed Zeke to any surviving Survey Corps member he could inject with the Titan serum. The Quadrupedal Titan surprises Levi when it charges at him and Zeke from behind and steals Zeke in its mouth, barely giving Levi room to escape. The Quad Titan then flees with Zeke, and the remaining Titans are ordered to kill Levi by the war chief. The two are then pursued by a determined Levi as he begins to take down the Titans and vows to keep his promise to Erwin.

The Quadrupedal Titan appears inside Shiganshina with Zeke on its back. It quickly makes its way over to Eren Yeager who is sitting on a rooftop holding Bertolt Hoover captive. It stops and stands by as Zeke and Eren speak. During this time, Zeke reveals that he knows Eren's father, Grisha Yeager. Before he can go into detail, Levi appears atop the Wall and jumps down to pursue them. The Quad Titan then sprints away at Zeke's command. After Reiner had been located, the Quadrupedal Titan appears out of nowhere and lunges at Hange Zoë, attempting to crush her in its jaws; however, Jean Kirstein is able to tackle her out of the way in time. Hange quickly gets to her feet, blade ready, but is shocked when she sees the Quadrupedal Titan holding her hostage, Reiner, in its mouth. It then makes off with him and is pursued by Connie Springer, who is then ordered to stop by Hange as she believes he will just have the tables turned on him. As Levi, Eren, and Mikasa Ackerman debate over who will be injected with the Titan serum and devour the now defeated Bertolt, Erwin or Armin Arlert, the Quad Titan climbs and reaches atop Wall Maria with Zeke and Reiner, looking on.

Trivia

 * There have been crawling Titans shown before in the manga and anime, but this is the first time a Titan walking on all fours has been seen being used to carry things.
