I certainly do! ^^ All my spams have an extensive backgroundstory, but here are their stories in a nutshell;
Avalon - from a shady Addison jeweler named Mauve to joining a thief's guild. Being framed by his thief family & becoming a wanted man on the run. He needed a new name & appearance and thus got a new thief life with a mission!
Othello - sole heir of the della Denotte noble family (no Addison form), once a brilliant scientist but became a maniacal madman because of his twisted & poisonous family. They put him in the Raveworth Institute (a lunatic asylum for the criminally insane) to break his mind. Othello is the only one who knows the combination to the safe with the della Denotte's precious heirlooms & treasures. He freed himself from his chains & medication, burned down the asylum and escaped. Wanting revenge, he returned to his family
to terrorize & exile them. Reclaimed his castle, title as Count and his rightful place & property/assets but made many enemies.
Ciceron - once a fortune teller machine (an amusement automaton & no Addison form), and part of the traveling vaudeville circus called 'Gran Sasso Incantata', led by the Cardini family. He combined his mechanical abilities with illusions & magic, becoming a showman and performer at the circus group but gained the attention of the evil lord Leister Montague. He sold his soul to Montague in order to compete in a competition to join a secret organization dedicated to promoting and advancing the art of magic called 'The Magic Circle'. Montague betrayed Ciceron & cursed him. He and Avalon work together to break the curse & reunite Ciceron with his family.
Zabulon - once a kitchen robot named Zabu 3000 (no Addison form), serving in a 3-star restaurant on a luxury cruise ship called 'Fortitude'. One day Zabu 3000 short-circuited, thought to be broken but actually slowly developed a conscience of its own - his owners Gilles and Anjou Lac, both chefs, used him as a killing machine for their schemes. They adopted him as their own son and named him Zabulon. He enjoyed the prestige and attention he gained. However, jealousy grew among the chef’s children. Now that Zabulon became their sibling, he also became a possible heir to the Lac empire. They tried to sabotage him time and time again which lead into Zabulon behaving more unhinged and deranged. The heads of the Lac family, Gilles and Anjou, enjoyed the rivalry of their offspring & even turned it into a cruel competition; the most successful descendant would inherit the entire Lac heritage and become head of the family. All the siblings accepted the challenge, Zabulon and his siblings became archenemies and are still at war. On his journeys, Zabulon discovered he loved one thing more in the whole wide world then adrenaline; chocolate. He tried different kinds of chocolate treats from all over the world and fell in love with the sweet taste, thus opening his own chocolate shop.
