With Mars in Leo the people are natural leaders and are blessed with abundant energy. These people tend to be at the forefront of any project or venture. Since Leo is a fixed sign and a sign that looks to itself for authority these people will not usually compromise on their ideas and visions and will not look to others for advice or direction. This placement can indicate a quite competitive nature if taken to the extreme, as these natives will naturally want to be at the center of events. Leading on from this there can be jealousy if they feel there needs are not being met. More often than not though other people will be naturally drawn to people with this combination as they likely possess a strong charisma and charm. This combination can also indicate people who have a strong sexual interest which is characteristic both of the planet mars and the sign of Leo
