Some of the things that happen to the Puzzle are kind of shudder-inducing, especially looking back on it knowing there was a soul trapped inside the whole time.

Worse, Yugi was imprisoned there briefly. In the manga Imori states that it takes the Jar about 3 months to fully consume a victim's soul, implying that you spend 3 months being eaten little by little.

Imori and his soul-eating Dragon Jar in Chapters 46 and 47 of the manga (and episode 18 of the Toei anime).

Shadi's Trial of the Mind in the manga had him brainwash Anzu by rearranging her Soul Room, then placing her under penalty of death to test Yugi.

In Chapter 5 Anzu gets knocked out with chloroform and it's implied that the guy who knocked her out wants to rape her.

Hirutani's gang tries to hang Yugi with a chain, and would have if Jonouchi hadn't saved him.

The chapter when Jonouchi has been forced back into his evil gang, but when he rebelled, they took him to a warehouse where they tortured him by beating him and electrocuting him with a taser.

Neither Ammit itself or Kanekura's shocked face is decent to look at, to say at least. Ammit towers over him, preparing to eat his heart, and the shock gives him a heart attack.

Kanekura's Penalty Game is disturbing.

Sozoji's Penalty Game was to be deafened by the sound of his own heartbeat.

The digital coloring of the manga makes it even worse, as the colors are bright and full of static. His Penalty Game was to see everything as a pixelated mosaic, which is represented by his eyes becoming pixelated.

The ZTV director filmed a documentary about bullying by making his assistant director beat Yugi and Jonouchi up.

He's seen the next day happily playing with leaves and trash. After fighting the urge to swing the knife as hard as he can, Ushio tries to stab Yugi, but is given a penalty game where everything he sees looks like money.

They'd take turns stabbing the bills, balanced on their hand, and whoever stabbed their hand first would lose. When Yami Yugi awakens, he challenges Ushio to a game involving money and a knife.

The very first chapter has Ushio beating Jonouchi and Honda up and forcing Yugi to pay him or he'll do the same to him.

Several of the Shadow Games from the original manga and the Toei anime are incredibly dangerous, and many of them are from the main hero's Superpowered Evil Side.
