Tyrogue become stressed out if they do not get to train every day. When raising this Pokémon, the Trainer must establish a regular training schedule.
(From Bulbapedia) 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.
(From Bulbapedia) 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).
(From Bulbapedia) 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.
