Michael Harkonnen Is many things; savvy businessman, shameless flirt, "connoisseur of fine dining a recreational alchemy" (His own words). Michael considers himself something of a renaissance man, possessing keen knowledge of everything he sells which ranges from weapons modern and ancient, antiques of mystical and mysterious origins(And fakes), furniture, camping equipment and substances one might argue are clearly narcotic, mechanic and bus driver. Very charismatic and polite, if unafraid to flirt with his customers (As both a business tactic and for fun) it's often hard to leave his story empty handed.

While Michael might come across as con, often trying to get customers to leave with overpriced or useless antiques, he'd never sell something actually dangerous, at least knowingly. Like most of the Harkonnen he possesses a sarcastic, dry wit, and is confident, taking pride in his outward appearance. He genuinely cares for his family and is very protective of his younger siblings, notably Kafzeil and Nyx.
