Tiara's assistant and best friend, Eric Hanna

Both Tiara's best friend and her assistant for all of her engineering and science related adventures, he's one of the main reasons as to why she's somehow never in much trouble whenever she experiments with any technology that has not been tested. Is also almost a big chunk of her impulse control as she's reckless and doesn't follow safety precautions.

He's the first to refer to Eric Astra (a figurine that was made sentient and life sized) Eric Astra Junior. The only reason as to why he has fingerless teal gloves is to hide a few scars on hands which aren't on his fingers. He has normal gloves.
