Cloud is a sarcastic, and cocky character and he enjoys provoking other people for his lols, the way he mocks Barret at the beginning of the game is a huge example. Also what he can say to Aerith. " Oh I remember you, you were at the slum drunk " ! He is also the character that can seem rather prefect to others, Aerith saw him as her prefect romantic bodyguard, Barret was jealous of him because he thought that he was a much better leader than he was, and Tifa saw him as her own 'superman', but inside he is actually pretty awkward and insecure about himself, and him trying to model Zack is a huge example of that, he doesn't believe that he is 'good enough' inside, even though others clearly idolize him. Cloud is also pretty revengeful, most of the game is only main focus is to get revenge on Sephiroth for destroying his village, and his desire for revenge gets even worse when Aerith dies.
Cloud is also the character that becomes more warmer towards others and more caring towards his friends once he gets to know them and have a stronger connection with them more, but just getting to know people, he's as coldhearted as ice. Also Cloud is a slow dumbass when it comes to love and romance. Aerith and Tifa flirt with him all through out the game, and he has no idea what they are on about, even during the Gold Saucer dates he's completely confused with Tifa's emotions towards him. Cloud in Dissidia however seemed rather Stoic, distant, and extremely calm. Though just like in the original game, Cloud doubted himself but most of the other Final Fantasy heroes thought that he was this ''amazing champion". Firion espically.
