The first kaiju that Ultraman fought on Earth; it is considered a devilish destroyer of the universe’s peace.
It flies in a blue photosphere, and attacks by emitting blue heat rays from its mouth.

As Ultraman was returning it to the graveyard far away in space, it escaped and descended to Earth. Landing in Saitama prefecture, it dove to the bottom of Lake Ryugamori to relax after its long journey.
It surfaced the next day, only to be met with Super Gun fire from the SSSP members that happened to be there. It tried hiding at the bottom of the lake, but the SSSP were able to attack from both the sky and underwater, thanks to Ultra Operation No. 1.
Bemular set the surrounding forest ablaze with its heat ray, then engaged in hand-to-hand combat with Ultraman, who weakened it with the Ultra Swing. After being thrown into the lake, Bemular transformed into a blue sphere and tried to escape but was struck by the Spacium Beam and exploded.
