When Ben was younger, he used to be cocky, childish, and arrogant, as Ben's immaturity and attention-seeking behavior often led him to joke around, regardless of the situation. His allies often criticized his attitude, unaware of the fact that he used his own humor to mask his fears from the enemies and the allies that he made. Despite some childish attitude, Ben was able to be heroic, caring and generally good-natured, always willing to save others at any time.

Over the years, when Ben grew older, he has displayed good leadership skills, as well as the ability to adapt his attitude to a situation, becoming serious when it's called for. He became more mature, responsible and sensible. He's kind-hearted, willing to sacrifice even his own life for others. His idealistic views and unwillingness to compromise his values – aspects condemned by Azmuth, yet commended by others – sometimes drive him to act against reason, such as helping his enemies if they need it (most remarkably Vilgax). Professor Paradox has praised Ben's good nature, going so far as to say he had the gift to make the right choices at the right moments. When he was younger, he often stated that he can be silly or unintelligent because of his immaturity, Ben is cunning and resourceful when needed, quickly adapting when he used his old omnitrixies as it doesn't provide him with the alien he wanted. But when he became an adult, he were able to become more serious, able to handle his emotions, don't think himself as a person who is able to get more glory through his heroic actions, he can be vicious if someone hurt himself, his family, his friends, and the people of the Earth and the universe. He can be goofy, use his humor, and have fun at times when he is in a good place.

However, when Ben fails to save someone, or if someone gets hurt because of his failures, he becomes angry and much more violent. Perhaps the most notable of these instances is when Kevin willingly mutated himself to succeed where Ben had failed and stop Aggregor, Ben was set on killing Kevin, even fighting Gwen when she refused to help him.  He also threatened to hunt down and destroy the Forever Knights once making Driscoll promise to cease the hunting of aliens. He also used to mutilate Vilgax in order to protect his family, his friends, the people of the Earth, and the universe from Vilgax taking over with his ultimate plan after Ben saw how Vilgax killed people in Bellwood with his very powerful wipe machine.

Throughout the B10K Flashbacks and the events of Ben 10,000 it is shown that Ben starts thinking of himself less and thinking about others as equally. But he can be serious, vicious, violent, humble, goofy, smart, use his strategy/tactics/operations through actions, reasons, and logics, creative, and caring. At times, he can think himself of a superhero but he know that he is also a Plumber, a leader of his own city, the leader of the Universe to protect.
