Level 0 Cogs are a type of Cog which used to appear during the Vice President battle. They could not be defeated, but appeared at the start of each Vice President battle. The only level 0 Cog to make an appearance is the Cold Caller. Their strength has not been confirmed.
- According to the Cog HP formula, level 0 Cogs should have two health points, which would allow any gag to destroy one in a single hit unlike the higher level Cogs. This includes a bike horn that only does three damage.
