LEGO 2236 Scorpio

Scorpio lives on the jungle planet Quatros. They are very rare, like most wildlife on the planet, and are considered an endangered species. Quite large and highly intelligent due to the planet's quaza, they are dangerous enough to potentially kill a hero. Scorpions can strike with their stinger tail, but prefer to stun their prey from a distance with their ball shooter on their tail for easy defeat. They wear heavy armor plates with spikes to protect them from the planet's other predators.[1]

Witch Doctor was able to equip a Scorpion with two corrupted Quaza Spikes, and could now control the creature.
