Tyrogue is a humanoid Pokémon with a predominantly pale purple body and brown hips and feet that resemble short pants and shoes. It has three blunt protrusions on top of its head, yellow eyes, and circular sections on each side of its head that resemble protective padding. There are white bands resembling bandages on its torso and wrists. It has thin limbs, and its hands have three fingers each. Tyrogue is a male-only species with no female counterpart.
Tyrogue is famous for its eagerness to compete and boundless energy, to such an extent that it will challenge anyone, even larger foes. Determined to make itself stronger, Tyrogue will not quit no matter how many times it loses. As a result, it is always nursing its injuries from fighting opponents larger than itself. As Tyrogue becomes stressed if it is not able to train every day, its Trainer must maintain a regular training schedule. It is usually found in urban areas.
Tyrogue's first appearance was in A Tyrogue Full of Trouble. It had been abandoned by his previous Trainer and left to fend for itself. Because of this, it developed a hatred towards humans. Tyrogue ended up forming a gang of Mankey and Primeape, and together they would steal from weary travelers, such as Ash and his friends. But thanks to a Black Belt named Kiyo, who had been pursuing him, Tyrogue reformed a trust with humans and ended up becoming his newest Pokémon.
Tyrogue is the only Pokémon whose evolution is determined by stats.
While Hitmontop shares the AbilitySteadfast with Tyrogue, Tyrogue is unable to retain this Ability after evolving. This is because Tyrogue's Steadfast is its second Ability, while Hitmontop's Steadfast is its Hidden Ability.
Tyrogue has the lowest base stat total of all Fighting-type Pokémon.
Tyrogue also has the lowest HP and Attack base stats of all Fighting-type Pokémon.
Tyrogue is the only Pokémon that created a shared evolution family between two Pokémon that were previously unrelated.
It draws inspiration, especially in its most recent artwork, from wrestlers. The designs on Tyrogue's body resemble the uniform of most scholastic wrestling teams—possibly showing its maturity as a fighter (a younger creature, while its evolutions seem more professional).
Tyrogue is a combination of tyro (a beginner) or tyke (child) and rogue (one who is playfully mischievous). Ty may also be referring to Mike Tyson.
