Cyclops

From Xiaolin Showdown Wiki

Cyclops is a giant one-eyed monster who Wuya and Jack Spicer had hired to get more Shen Gong Wu. It is unknown where he had come from, though Wuya is more likely to have found him, as Jack detests him for being hard to care for. He is powerful, but dim-witted, and has no depth perception due to having only one eye. He has also fired dark lasers from his eye on some occasions. First appeared in Sizing Up Omi.
