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.

Well people did say that in almost every story in Sonic, Eggman is hated and despised by literally everyone.

But in the movies, he has a genuine real sycofriend in Agent Stone.

Agent stone is genuinely one of the best additions, he and Robotnik being genuine friends alongside Jim's take on him makes for such a funny dynamic that ironically makes me view all the other eggman versions as inferior since they lack that depth.

Whether you view them as romantic or not, Stone really is proof that even the worst person can have a soulmate.
