Prometheus is a large sun, though is of course much smaller than an actual sun. It has several sunrays surrounding it. Its eyes and nose are very close together, and are small compared to its large mouth. It has blushy, rosy cheeks.
Prometheus is very loyal to Big Mom and will come to her when she summons it. It also cares about the safety of the citizens in Totto Land and may even question Big Mom and beg her to cease if it sees her tantrums are causing harm to others, but due to being a Homie it can never physically go against Big Mom due to fearing her powerful soul as all Homies do.
