The Tailed Beast Bomb is a massive, spherical energy attack with a dark core surrounded by swirling, vibrant chakra. The core is a deep black or dark purple, emitting a menacing glow, while the outer chakra layers are brightly colored, often in shades of blue, red, or orange, depending on the tailed beast. The surface of the bomb is highly dynamic, with energy constantly moving and shifting, creating a sense of immense power. The overall shape is perfectly spherical when fully formed, but during charging, it may appear more unstable and irregular.
