Gigi

From Xiaolin Showdown Wiki

The Heylin Plant, named by Jack Spicer as Gigi,is the plant that sprouted from the Heylin seed. He was at first commanded by Jack Spicer, although he quickly outgrew him. Gigi is so dangerous that its seed must be guarded in a chest, away from any soil, water, or sunlight. The only Shen Gong Wu that can defeat him is the Moonstone Locust.

The character of Gigi seems drawn from the French Taunter of Monty Python and the Holy Grail.
