Obito is a strong hearted ninja of Konoha and has always dreamed of being a great ninja like the rest of his Uchiha clan. Except that he lacks in many skills of a ninja and is looked down upon and made fun of by his team member Kakashi.
Obito shares many similar techniques custom to the Uchiha clan such as Katon and others, he though does have some type of eye problems and is always late to his missions and constantly makes up excuses that are very similar to Kakashi's. Obito is also a ninja who has great heart for his team mates and will die for them and do what ever it takes to help them, to him a team mate who doesn't care about his friends is even worse then trash. A line used frequently also by Kakashi.
Obito sadly meets his end by trying to help his friends and his body is crushed by a earth cave in technique. While he is near death his newly acquired sharingan is given to Kakashi as a gift for being promoted to Jounin level . After this we see nothing more of Obito but Obito plays a very vital role in the life of Kakashi and helps him open his eyes and is the one who forged the Kakashi we know today.
