Mackerel Bananya is one of the banana-dwelling cat creatures that appear in the Bananya anime. He is the younger brother of Tora Bananya. His personality is shy and reserved, yet he is dependable and deeply cares about his older brother, often worrying about Tora Bananya’s romantic interests. He tends to be awkward around girls. Mackerel Bananya looks up to Kuro Bananya as a role model and aspires to be reliable like him. In the story, he appears as a supporting character in both the original Bananya series and the second season Bananya and the Curious Bunch. His design is a greyish version of Tabby Bananya, with a striped pattern reminiscent of a mackerel. No specific supernatural abilities are noted; his role centers on his close bond with his brother and his steady, supportive nature within the group.
