Avogadro

The Avogadro is an enemy included in the Green Run map for Call of Duty: Black Ops II. It only spawns in the TranZit game mode.

Overview
Avogadro spawns when the power is first turned on at the Power Plant. Afterwards it has the ability to appear at any point on the map and attack the players with bolts of electricity. It also has the ability to stop the Bus, which will not start again until the zombie is killed or the players leave the Bus, although it should be noted that standing on the roof will not cause him to disable it. Avogadro can be damaged through melee attacks. An alternative means to dispose of him is by throwing an EMP Grenade at its feet, which will instantly get rid of it. It should be noted that you take care when throwing an EMP Grenade, because it may affect other areas of gameplay. Another alternative is to punch him twice with the Galvaknuckles which will also get rid of him.

Avogadro also plays a part in the Dr. Maxis path of the Tower of Babble easter egg, where weakening or defeating him will complete the easter egg.
