Tier: At least 9-A

Classification: Dinosaur, Sauropod, Apatosaurus, Longneck, Leaf-eater

Powers and Abilities: Superhuman physical characteristics, enhanced senses (All leaf-eaters have heightened senses of smell to be able to find food across deserts), large size (Type 0, roughly 8 meters tall or more with a stretched out neck), regeneration (Low, should be able to quickly heal injuries like Doc's scar)

Attack Potency: At least Small Building level (Comparable to his daughter. Has fought and faced many Sharpteeth, including Chomper's parents and Red Claw, though he couldn't win against them without extra help from other adults)

Speed: Superhuman to Subsonic travel speed with Subsonic attack speed and reactions (Comparable to his daughter. Can dodge attacks from other Sharpteeth, such as the Browridge Sharptooth)

Lifting Strength: At least Class K (Should scale to this casual feat. Comparable if not superior to the other Great Valley adults who have this level of strength)

Striking Strength: At least Small Building level

Durability: At least Small Building level

Stamina: Peak Human to Superhuman (Can continously run or fight for several minutes and trek several kilometers through desert wastelands and snowy mountains, though this isn't always consistent and given his old age he sometimes gets tired quickly)

Range: Several meters with neck and tail (Uses both like whips and battering rams against Sharpteeth)

Intelligence: Average (Fairly wise but still about on par with a human in terms of intelligence, albeit dinosaur vocabulary is quite limited since they don't use the same words as us, like calling the Sun the "Bright Circle." Due to the time period, things are unknown to him)

Weakness: None notable
