Robert “Robbie/Rob” Humerus, Sharon’s husband and Riley’s maternal grandfather.

Robert was a memory cell in The Brain in his youth, and he came across as friendly, gentle, funny, caring, curious, a bit klutzy and slightly forgetful in his elder age, but otherwise very intelligent. He also was a comic geek like Drix and read a series called The Adventures Of Mighty Cell, which was about an ordinary, weak-seeming white blood cell gifted with super powers. Like an early version of The Supplements! His geekiness aside, he is strong and steady, and even wise in some situations.

He’d met Sharon and fell for her strong and daring personality, and her free-spirited look on life. And she fell for him for his shyness and intelligence. They both immigrated to Hector when Hector’s mom was pregnant with him, along with Riley’s parents and a young Kevin. Riley was born shortly after arriving.

He was very loving to his wife and grandchildren, and was proud of his daughter’s work as a sensory cell.

Went the whole ‘geeky grandpa’ look for him, shorts included! And for Kevin’s 15th Birthday, a bit before the dreaded incident, he bestows him his chain, which is seen here and in my previous art of Kevin.

Inspired by my late grandfather Robert Hupe, Raine Whispers from The Owl House, Howard DeVille from Rugrats, Grandpa Max from Ben 10, and Ford Pines from Gravity Falls.
