Description
Gao Granner Buffalo is a heroic robotic entity within the Earth Granner defense initiative, exclusively partnered with Joe Pachero. Originating from America, he accompanies Joe to protect Earth from extraterrestrial threats. His default vehicle form is a green car with gold and grey accents, featuring distinctive gold antlers on the head, gold hooves above the back wheels, and front-mounted shovel-like drills designated as the Horn Bazooka. A Horn Shield stores on his left side, and an orange midsection enables docking for the Core Granner Buffalo car.

Personality-wise, he displays a showy demeanor, frequently seeking attention while sometimes unintentionally disregarding others' emotions. Despite this, he exhibits unwavering friendliness and profound loyalty toward Joe. He possesses a deep affection for bulls and cows, reacting aggressively to witnessing beef consumption. This devotion leads him to refuse combat against the Spinewger Gyuumooai, believing it to be a bull. His background includes prior unsuccessful compatibility tests with other potential partners before encountering Joe. Their bond solidified when Joe intervened to save a cow during a near collision with a herd, impressing Buffalo. Joe rejected the formal title of "Granner," proposing they become "family" instead, cementing their partnership.

In combat, Buffalo combines with Gao Granner Alligator to form Earth Granner Buffa Gator. This combined robot is predominantly green, displaying a buffalo-head motif on the chest with gold antlers, green shoulder armor, grey limbs, and gold hooves on the feet. The Horn Shield relocates to the back for defensive use on the right arm, while Alligator's tail transforms into the Pile Ax weapon. The Horn Bazooka and Pile Ax can merge into a Pile Hammer.

Key relationships define his narrative: his central bond with Joe reflects mutual loyalty and shared behavioral traits. He initially antagonizes Gao Granner Saber over Saber's alignment with adversaries but later pursues persistent friendship despite Saber's aloofness, signaling gradual reconciliation. During a crisis where the Earth Cave charging station was destroyed, forcing slow individual recharging, he prioritized himself ahead of others, causing friction. He sustained damage in an early confrontation involving the Drift Thunder Tomica, necessitating temporary repairs before returning to battle.
