Sandbag is an anxious, protective and hot-tempered person who often acts on impulse, believing very strongly in what it believes is right. He generally returns the attitude that others give him — he is overall nice to those he considers friends or allies, but is very distrusting and unfriendly to those who have been mean to him or those he looks out for. Sandbag is be extremely loyal to the people who have gained his trust and is willing to fight for them — namely Sailor, who Sandbag bonded over with for their shared love for the sea. Due to Sailor’s age and their close bond, Sandbag makes sure that no one dares to mess with his newfound friend. Sandbag mentions having a relative around Sailor’s age, which may be another reason why he is so protective over Sailor. Sandbag's appearance is fairly masculine, with tanned skin and multiple scars covering its arms. His hair is short and dyed blond. He seems to wear a sleeveless white collared shirt along with a black vest with lapels. There is also a messy black bowtie finishing its look. Sandbag's hands are protected with black fingerless gloves following with what seem to be white formal cuffs around his wrists. It is also wearing a bandana tied around his head, patterned with an open shark—like mouth and round yellow circle (resembling an eye). Perhaps because of Sandbag's paranoid personality, its upper face is always seen to be shadowed, representing his panic and discomfort. Sandbag also has a bright orange shark themed jumpsuit that it wears open to the waist, with black and blue trim. (Sandbag also goes by He/It pronouns!)
