a lot of people make fun of Silver the Hedgehog because his debut game was infamous, but his character motive is really interesting, just poorly executed.
The comics add a little more to the concept, but not much. This kid keeps finding different ways to travel back in time, believing that he can save the world he lives in by stopping a great catastrophe. Even when he succeeds and returns home, his world is still in shambles and he tries traveling farther and farther back in time to eliminate all possible problems. He's depicted as being both a hero, an enemy, and a general nuisance because people are tired of him showing up in their timelines to fix things and it's genuinely a trope I don't recall seeing much in other time-traveling stories. Except maybe Dr. Who? Idk it's been forever since I watched Dr. Who and I should sit back down with it.
Anyway, Silver's adventures testifies to his naiveté and his stubbornness. And I wonder if he'll ever think that some things are inevitable and it's not his responsibility to fix the past so much as do what he can in his current timeline. To be fair though, his current timeline is a dystopia where he's always fighting monsters or running away from being experimented on. Given how much he time travels he may just be numb to it all and constantly grinding in an attempt to make things right.
Also,,,, he loves gardening,,,, like if he lived a perfect life,,, all he would do is garden,,, and that's just endearing but makes so much sense, because he starts with nothing at all.
I know the Sonic series gets a lot of (deserved) jabs but this is pretty good writing that makes you invested and makes you think how you would respond to his existential dilemma.
