Tamka is a bulky green crocodile, with a large olive green spot at the end of his long snout, coupled with smaller markings of the same color also on his snout. The bottom of his black eyes green. Some light green markings reside on the side of his ribs. His underbelly is also light green, with a couple of dark spots near his chin. At the end of his tail is a light green stripe, and his tail is tipped with the same shade of green. His scales are dark green, and his claws are black.
Tamka is shown to be overconfident, and lacking in intelligence. He even confesses to the Lion Guard that he himself is not smart. Despite his physical stature, Tamka has been shown to be rather weak, with Kion able to take him down without any problems.
