FrankenBug is a modified Large Bug that the Dark Union has been experimenting on. Since it’s not a finished unit, it has no primary gun, and it’s armour plating is not complete– revealing the somewhat disturbing flesh and circuits underneath. FrankenBug is a Boss in Algernon's Laboratory.
- FrankenBug's name derives from Frankenstein, a fictional scientist who created a monster using dead corpses.
- Although FrankenBug is a modified Large Bug, its looks are very similar to a Scorpion.
