this is a rather incomprehensible contradiction. Can fate be changed or not? if we judge from your words that the birth of the MC led to the butterfly effect, then fate is at least flexible enough that it could be changed. however, if you want to make it look as if fate is almost impossible to change, then the butterfly effect is impossible, and the MC should act as a story furniture. excuse me, of course, you are getting gibberish. decide what place and role fate and the future occupies for you.
Marcel is alive in this story ... so Rainer died? did Ymir get the armor this time? or else Marcel was smart and instead of allowing himself to be devoured, he transformed and killed the titan? If Rainer died, then the Armored was stolen by some other titan, and this further reinforces my theory that the protagonist could stay with the Founder, If the author is concerned about the lack of physical strength of the original titan, just find some way to make the protagonist eat the armored titan, as this would give a great boost of strength But at this point in the story, I don't know if the protagonist has a chance to win only the Founding Titan, because if my calculations are right, Grisha went to steal the Founding Titan when he left home, Right after promising to show Eren the basement So probably the Founding Titan will be by the Attack Titan by the time Grisha returns to the walls
