In April 2001, the original 1997–1998 shorts were remade and released on Mondo Media’s flash cartoon site in the United States.

It is demonstrated many times throughout the series that Kevin is mentally unstable, as he is prone to random outbursts of violence, even towards himself, shows signs of insanity, and has a complete disregard for life, including his own.

It is also shown that Kevin is probably mentally challenged, as he often has difficulties with performing the simplest of tasks, such as making himself a bowl of cereal, forgetting what he was talking about the instant after saying something, or even realizing that he was hungry, yet at times throughout the series, makes very well-articulated statements about certain aspects of society, culture, politics, and education, possibly indicating Kevin is a savant.

Throughout the series, Kevin almost never speaks, aside from during dream sequences and occasional one-sentenced outbursts that the viewer only sees as speech or thought balloons.

While both parents primarily show hatred and disgust towards one another, both occasionally demonstrate a small degree of lust for each other, though these moments rarely last longer than a scene of an episode.

Allen often encourages Kevin's sociopathic nature, noally asking him to do illegal, indecent, and/or dangerous things simply for the sake of the thrill or for vengeance.

In the final episode, it is revealed that the entire series is actually just a mental delusion created by Allen himself, and he has been seeking therapy to regain his sanity.
