Captain Planet and the Planeteers

In Zarm's Way (5x9)

Air date: Feb 04, 1995

Zarm returns yet again, this time to test how "good" humans are, he tells Gi that, in order to save two children whose lives are at stake, she must somehow convince him of the goodness in human beings. Pushing his experiment up a notch, Zarm uses the power of hatred emitting from the parents of the children to transform the once; innocent kids into REAL "Little Terrors"
