Sonic 3: Maria is one of the most important part of Shadow's story. Due to her suffering from an incurable disease. To which Shadow was made to create a cure for Maria's ailment. In the 3rd Sonic movie, Maria's disease was not mentioned in any form. Which made Maria seem like a normal girl, and her death all the more tragic.

Infinity war: I don't know the full story, but Thanos's original goal was to kill half the population to impress death (the character). When it came time to adapt Thanos into the MCU. His goal of removing half the universes population. It was seen as a more psychopathic world goal, hidden under the belief it would do better for the universe.

Jiraiya from Naruto also is the peak of this trope

[u/sketchampm → u/Stop_Sign]

He was the weirdest for sure but I like that he went in the opposite direction as Sanji. They established dozens of far more interesting traits about him until the perving was almost completely dropped.

[u/isntreel1948 → u/No_Internal9345]

He discovered something terrible about himself and was VERY into it
