Either way, Nomura has quite a bit to answer for it.

See, before Smash 4 did the Smash thing off reviving more classic looks, personalities and designs, every subsequent thing after VII (not counting certain cameos playable or otherwise like Tactics) had this dumb fascination in making Cloud a mopey loser.
Hell, the reason Vincent (you know the actual brooding guy from VII) didn't show up in Kingdom Hearts was because they foolishly got the idea that he and Cloud were practically alike. Started with Kingdom Hearts, seemed like it might have been going away after his "arc" in KH1 was done...... and then Advent Children happened which also led to other stupid exaggerations like the size of Sephiroth's sword and yes even Sephiroth kinda got flanderized. Even worse, Dissidia also decided to get on that stupid train. It was getting pretty BAD for FFVII and Cloud fans who had to put with misconceptions of Cloud's thanks to Square themselves. Hell, some people fear the remake because of that. That is until Sakurai and Smash enter the picture.
Right down to the pose, Smash 4 gave Cloud his wit, his strong nature, his upward stance and not that "crouching crawling in my skin, I'm sick" stagger, and the "let's mosey" personality. Funnily enough Dissidia NT seemed to get that message too.
That's one of Smash's powers.
