Envy: 3 things or people your character is jealous of
Kakashi Hatake. Obito always had and mostly will forever be jealous of Kakashi. As a grown up he is better to hide his feelings, but he knows that Kakashi is smarter, that people trust him more, that he is the favorite of everyone, while he is just second choice. Since he loves his best friend, he is able to ignore these feelings really greatly. Only sometimes they show up.
Itachi Uchiha. The prodigy. The strongest and best of their clan… He was better in everything than Obito. Even as little kid Itachi was more skilled with a kunai then Obito could ever be. He likes Itachi as child, even when he sometimes glares at him for being so much better, being still over 9 years younger.
Naruto Uzumaki. He truly likes the blond brat, but he has problems with him. He knows that Naruto went through a hard time with having the nine tailed fox sealed inside of him, but still, he is jealous of the kid. Mostly just because Naruto has such a strong will and a gentle soul. Obito himself lost most of himself after the boulder pressed the life out of his lungs. He doesn’t hate Naruto, no he sees him as something like a little brother, but he is jealous that the kid is able to move through so much pain but still being strong, while Obito would have given up on half the way.
