Hadro is an aptonoth and Pitbull's pet. She has sandy colored skin, brown back, and amber eyes.
While in the Monster Hunter universe, the team comes across a fighting arena created by hunters. They infiltrate the arena by putting their own rescued beasts into the fights. They all only pretend to fight each other to give the others time to rescue the trapped beasts. Pitbull rescues Hadro and he's grateful.
Hadro is a fearless and a brave young aptonoth with a strong sense of adventure. She often doesn't consider her own personal safety. She is rather dimwitted creature, being laid back and never holding violent tendencies towards anyone. However, she is hostile to unwelcome targets.
She has thick skin and a flat, blade-like tail.
Trivia:
Hadro's name means Bulky or Thick.
She's the first non-aggressive monster introduced.
