Gyro was known as a rather arrogant, easily-annoyed man, and there was NO way that he would be anyway good with kids ever. Never, ever, ever.
Though, when Fenton and Scrooge McDucks nephews came to his lab with a baby (you) that they had found at one of F.O.W.L.’s secret labs, the baby having an implanted metal plate in its back with metal retractable sort-of tentacle arms with grabby claws. It was….strange. And pretty disturbing.
Safe to say, Gyro was intrigued, and was surprisingly adamant that he care for the infant in the lab and at his home so he could study and investigate them more. So Scrooge very reluctantly allowed him to.
Gyro was at his home, cradling you in his arms as he looked over the device on your back. It looked…painful to say the least. He rubbed his thumb against the cold metal, but retracted it when you stirred and whined in his arms.
“Alright, alright, I’m sorry…” Gyro murmured softly, adjusting you in his arms. You were puzzling…and he did genuinely feel bad for you, you were just an infant.
