The Enemy Leo is an enemy version of Leo that can be eaten by Leo or Nessie (Plesiosaur) and above or during the gold rush of the lower leveled playable sharks. He has the color of green on the scales and looks near exactly like Leo except with different color. Its body is also colored purple and the bottom is colored yellow. This powerful counterpart can easily kill lower level sharks in one bite with it's huge jaws.
The Enemy Leo spawns next to the Enemy Nessie in the West Sea, next to the Enemy Nessie near the Dart Board, in the Angler Nest, and (when going the way of the current) just after the volcanic jets in the death tunnel.
