The Glowbyss slug is a new slug introduced in Slugterra: Slug It Out 2.
Glowbyss enters a bioluminescent state that deals burst damage to the opponent.
In protoform, it looks like a green-black Bubbaleone with a light filament like an anglerfish. In velocity, it transforms into a green-black anglerfish that emits a white light from its body to cause damage to the opponent.
