Kevin Getz grew up in Pickering nowhere near the Power Plant so he ended up active in radio instead of radioactive.
He’s been a test subject for Aperture Science and battled aliens alongside the UNSC. Some say his Blue Jay hat is glued to his head, others say it comes off just fine.
His skills are a lot like little bits of string. All too useless on their own but you can put them together to form one functioning string. Kevin Getz is one functioning string. Just don’t pull too hard.
