Appearance and Abilities
The Ape Titan is 17m in stature, larger than the common 15m Titan.

Trivia

 * The Beast Titan's appearance resembles several ape-like cryptids, such as the Sasquatch/Bigfoot, Yeti, and Yowie.
 * The Beast Titan is the first Titan fully capable of advanced communication, speaking the human language effortlessly. It also shows greater dexterity and fine-motor control, allowing it to remove Mike Zacharius's gear without damaging it.
 * It appears to have had limited or no contact with humanity for at least half a century, as it expresses interest in humanity's Three Dimensional Maneuver Gear. It also wonders whether or not it speaks the same language as Mike, though it's unknown whether this was genuine or simply mocking his terrified state.
