Bambi: The Reckoning

In the past, a young fawn named Bambi lives happily with his mother until a poacher kills her. Bambi grows up alone, but meets a doe named Faline, who then gives birth to a fawn. Unfortunately, Faline is fatally run over by a truck carrying toxic waste, and Bambi's offspring disappears. Devastated, Bambi drinks contaminated water from a river, which mutates him into a ravenous creature, determined to get his revenge.
