Biro is an interactable NPC in Oh So Hero!

He is an alien bureaucrat/diplomat visiting the world of Aeter for the Gerrabacco Tournament. He identifies himself as such when conversed with by Joe. Biro displays a fondness for the planet and a sexual attraction towards many of the planet's denizens. He resolves to visit the planet more often, presumably after the Tournament is finished.

Biro is a short and chubby bipedal avian with Anzac feathers and Burnt Sienna beak and 3 toed talons. He protects his modesty with a pair of steel gray swim trunks with mustard yellow stripes. He has dark half-lidded eyelids. A white towel is slung over his shoulder.

Biro can be found in Smol Beach alongside many other NPCs. He can be found a little past the halfway-point of the location on top of the raised platform between Officer lance and Chad

• Just like the Daku or Amaru, Biro is also introduced as an alien visiting planet Aeter.
• Biro's design somewhat resembles that of an anthropomorphic Chocobo from the Final Fantasy video game series.
• Biro is an original character that was designed and used before the game, similar to Ket by Ket Ralus or Veene by Red Emption. In the case of Biro, he belongs to the artist known as Arty Stu.
• Biro cameos briefly in Crooked Knobs by Arty the Frog. This is a similar case to Officer Lance except Biro isn't a main character like he is.
