Aberrant Gigantopithecus

Tank

Excellent tank due to its high HP and ability to wear any type of helmet.

Level up: in Health and Damage

Damage

Very good AOE, damage scaling and knockback. The knockback has also been known to push back a Brontosaurus slightly.

Level up: in Damage, Health and Speed slightly

Armor killer

Damages through player's armor easily much like Arthropleura in Pvp.

Level up: in Damage, Health and Speed slightly

Transport

Decent base carrying capacity but nothing absurd. Good base speed, similar to a player without any speed upgrades and can travel up and down ziplines like the ravager.

Level up: in Speed, Stamina, and Weight

Shoulder Carrier

Ability to carry shoulder pets (Such as Charge Light Dino, Jerboa, Microraptor etc...) with good base speed.

Level up: in Speed, Stamina, and Weight

To pick up a shoulder pet on XBOX use LB + Right Stick, same to throw the shoulder pet,

For PS4 hold L1 (alternate hand) and then press and hold R3, same action will spawn a crosshair to throw the pet

Gatherer

Can gather fiber, thatch, wood, and a decent amount of berries. Can gather fiber and rare flower passively when not ridden–will gather fiber from plants in its vicinity, otherwise turn on ability to wander to gather fiber continuously. Use (RB on Xbox) to gather Fiber while ridden.

Level up: in Damage, Weight, and Stamina

Hiker

Gigantopithecus may outmatch Pulmonoscorpius and Beelzebufo for hiking. They can climb the steepest surfaces with relative ease. And can also climb ziplines being very useful in Aberration and the underground forest in Extinction.

Caving

Arguably the best mount you can travel through in caves. Small enough yet deal significant damage and can run fast enough to avoid fights. Should you get caught up in the lakes you can swim to safety.
