Orochimaru was an orphan who studied under Hiruzen Sarutobi with Jiraiya and Tsunade. In comparison to the more laid-back Jiraiya, Orochimaru stood out as a genius—Hiruzen judged his abilities, knowledge, and resolve to be those of a prodigy seen once in a generation. However, while Jiraiya enjoyed traveling around Konoha, fighting evil, and having fun, Orochimaru used his intelligence to create weapons and technology that would make him seem like a demon to others. As time passed, Orochimaru gained power over both Heaven and Earth, until he declared himself "the true king of the ninja". At this point, Jiraiya left to train under another sensei and never returned. All that remains of him are two scrolls containing techniques that only he knew how to use. Tsunade also left home when she was young. She grew up under the care of her father, who was obsessed with creating powerful ninja. When she became old enough, she decided to leave too, but not before teaching Orochimaru her medical skills so he could fight along side her as a surgeon. Orochimaru has no real family or friends other than his many slaves who will do anything for his favor. He is cold, ruthless, and will stop at nothing to get what he wants.
