It's hard to associate anything vital to a character supposedly influenced by the power of Venus. This planet, according to astrology, is useful for very little. Fashion and vanity are obviously not things that can be used in combat against alien threat. However, Venus does have some qualities that are extremely useful during times of war, even more important than the ones doing battle.
Venus exhibits motherly love and bestows a pleasant, nurturing and caring affection. The warm of this universal love comforts comrades whom are emotionally wrecked by the on going struggles between good and evil. She is also an aide to those casualties of war as well.
