Mega Sonic Bros. AFEdit
Mario's personality has not changed much from the games, and is possibly the least developed of all the heroes due to his lack of speech. He is optimistic, often finding the best in situations and using them to his advantage. He's generally more willing to solve a problem with action rather than analyze the situation. He has a strong sense of justice and morality, often putting the needs of others above his own as shown by his frequent battles against evil. He cares about all the other heroes, and is always willing to help them if they are hurt, even Shadow, who often insults him. He seems to have an overall friendly relationship with Sonic, often teaming up with him in fights, saving him from drowning in the Minus World, attempting to comfort him when he is saddened by Shadow's departure, and checking to make sure that he was okay when he fondly remembers flying with Tails. Mario holds a slight resentment against villains he has encountered before, and holds great resentment against those who hurt innocents, such as the Axem Rangers X. He is the most notable one who is mostly despised by the villains, such as Mecha Sonic and Dr. Eggman.
He does have weaknesses in his personality, in that he is unwilling to allow others to be harmed as a result of his actions.
