Deal is a Lilim; his specific make of Lilim is a DT-01d. Although a social development robot, DT-01d's are "work Lilim", designed for resilience. He is rather strait-laced and matter of fact most of the time.
He has an extreme love of dogs, Corgis in particular, meaning he greatly enjoys his work at the Seifar Toy Company. According to Betty, he sleeps with a Corgi plushie and has a wall dedicated to photos he's taken at the company.
He does not enjoy alcohol much and is not a big drinker.
