The Timeline Loops (Premise) (TTL)

As i'm sure you know, there exists a theory of multiple timeline existing parallel to each others, each timelines are different from one another with small choices here and there that end up changing everything... yet there are 3 timelines who repeat one-another with only minor differences to one-another... More specifically, three Hunger Games... Your job will be to figure out how to change these and prevent the timelines from repeating.

The first timeline will be the one where none of the characters know about the timelines looping.

The second timeline will have very specific key characters that will have a sense of familiarity but not quite know what is happening

The third timeline will have the characters know that they don't just have a sense of déjà vu but attempting to change it

Every time the hunger games end with Skeloetta as the victor, the timelines suddenly repeat, never stopping until someone stops it, however things are not as simple as to simply kill Skeloetta, as another force will attempt to stop you from doing this.

The only way to stop that force is to weaken it, and the only way to weaken it is to change everyone's fate.

In order to change fate you could attempt to kill each person in a different method or help them live.

Another thing, every character will only have the sense of déjà vu upon starting the game when they are already in the arena, so trying to stop yourself before the game even begins is impossible

So tell me now, how would you change fate?
