Yeah because BLM represents all black people , right ? How ' d you like to be represented by all the neonazis that voted for Trump ? <| sep |> I would have to reject this theory on the basis that being extremely large is an ability worth having for combat and defense . while releasing steam is , at face value , not . Sure , defensively it may obscure the battlefield momentarily , but if the cost of that is a smallerweaker body that is not a trade that is going to work out well most of the time . I just can ' t imagine the original Ymir Titan saying to one of the 9 torch bearers before she dies And for your sliver of my power , you can get very very hot and release steam . Have fun with that ! Sure , we could hypothesize situations where steaming might be useful , but they would be quite specific as opposed to the general utility of being colossal . I honestly think the heat is just a function of the Titan makeup and is especially prominent in the two largest examples we ' ve seen Bert and Rod .
