Drystan McKenna is an anthropomorphic albino cat with pure white fur and red-tinted eyes, often wearing protective glasses and a glowing blue crystal tag. Beneath his feline form, he is the displaced identity of Otis Thatch, a former human tied to the lost Atlantis expedition and twin brother of Milo Thatch.

After a long and fractured history involving betrayal, wandering, and cosmic-level interference, Drystan was forcibly transformed into his current form and eventually chose to remain in this world, building a quiet civilian life from what remained of his past.

He now works as a substitute history teacher at River Ridge High School and lives a stable home life with his wife, Heather McKenna (née Bigglesworth). Together, they are raising six kittens:

• Liora — calm, observant, emotionally perceptive

• Rowan — curious, energetic, adventurous

• Iris — gentle, thoughtful, quietly intelligent

• Soren — analytical, structured, problem-solving focused

• Nova — bright, expressive, emotionally reactive

• Ember — bold, playful, impulsive

Despite his soft-spoken nature, Drystan carries the weight of extensive trauma, strategic experience, and long-term emotional restraint. He is highly intelligent, analytical, and cautious, with a strong instinct to protect others—especially students and his children.
