Backwater

Backwater is an Equestrian seapony from the pre-Queen Novo days of Seaquestria. He is a sea snake-based seapony and one of Novo's old friends and former bullies since meeting Princess Swellsea and is Queen Abysswish's former general of her army who is extremely rich in ciguatoxins, making him a deadly fighter who can poison his enemies with snake fangs. Very unsupportive of Abysswish's mentoring of Novo and Novo becoming queen and believes that false seaponies were unworthy to rule the underwater kingdom, he supports Tidecaller's attempts to overthrow Novo.
