Rafflesidon (ラフレシドン, Rafureshidon; Viz: Lafreshidon) was a Mysterious Being that appears to assist Senior Centipede in fighting Metal Bat. He was killed by Metal Bat.[1]


Raffleisdon bore a great resemblance to the rafflesia flower albeit with slightly more rounded features. However, despite its great resemblance to the flower, it had two eyes with completely black sclera and white irises. It had a bulbous nose with a wood like texture to it. It also had many of his roots sticking out in several directions.


It was rather calculating when it came to battle, relying mostly on others to distract an opponent while Rafflesidon releases gases to manipulate the battleground.


Human Monster SagaEdit

Monster Raid ArcEdit

After Senior Centipede knocked Metal Bat and the Heroes Association's sponsor and the sponsor's child outside of the restaurant, Rafflesidon emerged from the sewers and started releasing sleeping gas. The sponsor and the sponsor's child immediately fall unconscious. Rafflesidon and Senior Centipede are left to fight Metal Bat.[2]

While Senior Centipede and Rafflesidon fight Metal Bat, Rafflesidon is able to get Metal Bat into a hypnotic state. However, Metal Bat eventually comes out the hypnotic state after bonking himself, much to Rafflesidon's surprise. Rafflesidon is then defeated by Metal Bat with one strike.[3]
