His chosen form was of a giant bull. He fell in love with a mortal named Deianira. Deianira was also an interest of Hercules and so, Achelous challenged him for Deianira's hand in marriage. As the battle raged on, Achelous transformed into a bull and charged at Hercules. He avoided the attack and shattered Achelous' right horn.
