Every Weapon In Wonder Woman's Arsenal
6. Her Tiara / Headpiece
Diana's headpiece is a symbol of her royal status as Princess and is part of the set of weapons and armour she was given before leaving Themyscira. Usually appearing as gold or silver with a star in the middle, it adds a measure of protection to Wonder Woman in combat while still letting those she is facing off with know that they are dealing with someone who is probably out of their league in what's about to go down.
However, it is also a formidable offensive weapon in its own right. The edges of the headpiece are sharpened like a blade and cause massive edged damage when thrown with Diana's strength and expert aim behind it.
In addition, it returns to Diana like a boomerang, which means it is instantly ready to be thrown again. Wonder Woman's own durability ensures that she won't be cut by her own weapon when wearing, throwing, or catching it.
The beauty of this weapon is its deceptive nature. It appears to be just a simple headband, until flying at you at supersonic speeds like a whirring boomerang of death.
