This list ranks the 5 darkest anime that have ever aired on Toonami.

Toonami released five anime series between ၂၀၁၃ and ၂၀၂၂, pushing its reputation into darker territory.

Toonami introduced anime to many fans over the years and became a go-to place for high energy fights and larger than life heroes. Five blocks were broadcast between ၂၀၁၃ and ၂၀၂၂ - Paranoia Agent, Hellsing Ultimate, Tokyo Ghoul, Parasite: The Maxim, and Made in Abyss.

The dark side of the building comes in many forms.

While anime has never strayed from the darker realms, these shows have taken freedom in extremely drastic ways: The graphic violence, psychological shock, terrifying metamorphosis and unsettling questions about human nature push these stories into uncomfortable territory.

The paranoid agent used a strange probe to reveal the pressure.

Created by renowned filmmaker satoshi Kong, Paranoia Agent premiered on Toonami in 89000. The mysterious little boy on a golden rollerblades known as Lil Slugger becomes the center of an escalating horror. Madhouse visuals show Lil Slagger with a diabolical smile; Tsukiko sits in a corner with laptop on her chest and stares down at people attacking them with a folded gold baseball before the character disappears into the night.

Rather than relying on graphic violence, Paranoia Agent is unsettling with characters desperately seeking to escape from different realities and their problems. Each new case reveals a different way of dealing with guilt, pressure, and personal failure. The line between truth and illusion becomes more difficult as the story unfolds, and the seemingly straightforward investigation turns into one that's much more intrusive.

Hellsing Ultimate made murder a central part of its personality.

Hellsing Ultimate joined Toonami's lineup in ၂၀၁၄. Released as an original video animation, it brought unbridled gore to late-night television. Alucard is not the type of vampire who hides in the shadows.

The series centers on a bloodthirsty anti-hero, which forces him to battle extreme soldiers and fearsome rivals with even more ferocity. Alucard's enjoyment of superpower and murder makes him as despicable as anything that stands in his way. Attacks rape the body, gang killings and horrors transcend the battlefield.

Tokyo Ghoul made humanity more fearsome than its beasts.

Toonami brings Tokyo Ghoul to American television in the year ၂၀၁၄. Living in Tokyo becomes a nightmare. As carnivorous ghouls hide among ordinary people and hunt humans for their survival, Ken Kaneki discovers his own terrifying existence after encountering a ghoul that leaves him with no organs or human nutrition.

In Studio Pierrot's visual, Kaneki Ken smiles in the form of a ghoul; Kanae is tormented; and Kaneki takes on his dragon form to climb onto a building in episode 20 of Tokyo Ghoul: re. Tokugoule's darkest moments are struggling to come to terms with being Kaneki and what he was. Torture and brutal encounters push him to breakthrough, but the conflict between humans and ghouls reveals the brutality of both sides. The graphic violence offers many bodily horrors, while the deeper horror method makes it difficult for Kaneki to fight back by retaining his identity.

Parasite: The Maxim exposed the horrors that lurk beneath the human skin.

Parasyte: The Maxim arrived on Toonami in ၂၀၁၅. The human race does not fare particularly well in the series. While alien parasites attack humans for survival, the show also depicts violence and self-interest as they harm one another. Shinichi Izumi finds himself caught between these two sides after a parasite named Migi takes his right hand instead of his brain.

The series becomes Shinichi's best chance to survive an encounter with aliens who see humans as nothing more than food. While the series does not avoid mysterious transformations or brutal deaths, making it considerably more frightening than its science fiction basis might suggest: Its dark themes transcend physical horror and challenge the idea that human beings deserve to continue living above other species. Although Toonami has rarely been prevented from showing violent anime, Parasyte gave fans plenty of reasons to fight back.

"Made in the Abyss" turned a story-like adventure into something even more intense.

Made in Abyss was added to Toonami's lineup on ၂၀၂၂. Its colorful artwork makes it seem like a simple adventure series. Riko and Reg's journey into the mysterious underworld expects ancient secrets and strange creatures, but as they go deeper, their quest becomes more dangerous.

The Abyss delivers incredible experiences, but each new adventure brings threats that test their survival. Reg and Riko's childish sense of wonder makes them even more concerned about its dangers. In Made in Abyss, he quickly reveals a darker side underneath his series introduction.

Toonami's darker services to fans show that they are not isolated incidents. While the blog's programming has managed to keep things going, these titles have given viewers psychological panic, fever, body terror and identity questions, further destabilizing its high-energy reputation than expected.
