Overfilled Coffee

Biography
Overfilled Coffee has the base personality of being optimistic, energetic, and a good hearted person by default. However, by filling him with more coffee liquid or dumping some, his personality changes. There are also different kinds of drinks he could be filled with, of course, which changes his base personality.

Bio/Backstory: One day, about 17 years ago, in a coffee factory which produced coffee cups which were pre-filled, a coffee filling machine malfunctioned, making the next cup in line an overfilled coffee cup. When the coffee was at the inspection booth, however, it was alive, due to unknown reasons, likely possession. It said "Ooh, where am I?" and jumped out of the booth, observing the place while running, as an alarm sounded and workers chased him. He went to Fivia last year, however, and it's a mystery of what happened after the work incident.
