The Black Hole Whale appeared in 2015 manga called Toriko. The Black Hole Whales are an incredibly rare and powerful race of whales that hail from the Gourmet World region of Area 6. One of their members, Moon, is the current "Whale King" of Area 6 and one of the powerful Eight Kings.
The species gets its name from the fact that it can absorb almost anything it desires (even moon-sized objects) as though it were a Black Hole, and the entire region it resides in is completely devoid of light, further enhancing its resemblance to a Black Hole.
The species appear to resemble something akin to white blue whales with two pairs of eyes, lengthy whale arms, pectoral fins and a long serpentine tail.
Powers and Abilities[]
The Black Hole Whale is reputed to absorb all light and matter. It is this ability that hails Moon as the one King that has the greatest power among all the Eight Kings, and as such it is presumed to be one of the strongest creatures in the whole world.
