Personality[]
Being a bully, Flats is very sadistic, merciless, rude, intimidating, and unrepentant for no apparent reason. This is established when he reveals kicking other people's butts as his main interest. This is also evident when he still wants to hurt SpongeBob even after the latter saved his life from a vehicular accident, showing no remorse to the situation whatsoever. He is also shown to be disrespectful to authority figures, as he confronts his dad about talking to strangers and threatens to kick his butt. This intimidates his dad, who is too scared to punish his son for his actions.
Despite his rudeness, authority figures view his threatening behavior as friendly and well-intentioned, when it is anything but.
