The Brute Fish is a very muscular and rather disturbing purple fish seen (currently) twice throughout the series. Once in "Sentimental Sponge" as the garbage man, as well as "Kracked Krabs" as a hotel bellhop.
He has purple skin and a very muscular body. He seems to always be frowning or be angry. His clothing depends on his ocupation. In Kracked Krabs he wore a green bellhop uniform and in Sentimental Sponge he wore a white shirt and overalls.
