New Donk City is one of the most interesting environments to explore in Super Mario Odyssey. However, it also poses some serious questions when it comes to Mario's identity as a human. The design of the city's populace isn't just visually inconsistent; it raises questions about the lore.

The realistically-proportioned humans of New Donk City feel out of place with Mario's cartoony figure jumping all over the place. Does this mean that Mario is an alien? Is he a human being from an alternate universe?

On the subject of New Donk City's humans, the identity of its mayor is also somewhat curious. In a city full of realistic humans, it's weird to see that Pauline, who has the same cartoonish design as Mario, reigns supreme as their mayor.

These inconsistencies have driven many fans up the wall. While gameplay might be the biggest focus of a Mario game, that doesn't give Nintendo a free pass to have lore and design inconsistencies left and right. Ultimately, they're distracting and pull players out of the story.

Peach is one of the most gullible and fragile characters in gaming history. The industry has long since moved away from the damsel-in-distress concept, yet Peach winds up kidnapped in every Mario game regardless.

With any sense at all, the residents of the Mushroom Kingdom would've wisened up to Bowser's antics and put measures in place keep Princess Peach, their kingdom's royalty, completely safe from any harm. This doesn't seem to be the case, and Mario needs to step up to the plate every time.

Super Mario Galaxy is one of the greatest 3D Mario games ever made. However, it also messes up Mario's lore even further by giving him the ability to breathe in space — and no explanations whatsoever for this talent.

In this game and its sequel, Mario can breathe in space without issue. This goes against Mario's appearance in Super Mario Land 2, where he needs a proper space suit to roam planets other than Earth. Just when did he become so powerful?

Mario is one of the most versatile characters in gaming history. He gains a ton of powers over the course of his games, which end up making him an extremely powerful plumber.

However, Mario never manages to take what he's learned in old games and apply them in newer ones. While this is likely done to make the gameplay of each Mario title feel fresh, it does come at the cost of narrative inconsistencies when Mario is so weak at the start of each game.

Given how child-friendly and accessible the Mario games really are, this disturbing easter egg in Super Mario Galaxy 2 feels all the more sinister. Players can witness this secret in the Shiverburn Galaxy by going into first-person at a particular point in the map.
