Using advanced algorithms, Toximo is the most efficient and notorious polluter this town has ever seen. It was originally a recycling bot, but its program became corrupted when the boss hacked the recycling protocol at the station. Besides environmental pollution, it also believes in noise pollution by listening to hardcore death metal and new age music.
Each mastery level adds another card to the cardpool for defeating Toximo 3000. Each of the bronze, silver, and gold mastery levels unlocks a new card, while it takes all three diamond and onyx levels to unlock a single card.
