Here are most of Eduardo's/Edward's form so far:

Human - Base and balanced form. Utilizes his fighting style much better in this form.

Werewolf - a What-If form of Eduardo after being bitten by Joey. Powerful, but has no control over his form and must be rein in by Joey. He does have lapses of lucidity and tries to keep himself in check.

Dog (Old English Sheepdog) - Eduardo's Beast form, though due to his curse, transforms at random. A defense oriented form as he uses it to shield his friend from oncoming attacks. This form also has varying degrees of changes, from an anthro weredog, to a feral dog. Eduardo has gotten better at managing his transformation to where its not becoming a serious issue now.

Lion - Edward's Beast form, created by Kiyoshi to help him fight other monsters. An offense oriented form that allows Edward to fully utilize his fighting techniques and give them a boost in power. Mixing in feline agility and instincts, this form makes Edward a formitable opponent.

Owl (Snow Owl/Great Horned Owl mix) - Edward's Avian Beast form, hastily created by Kiyoshi to rescue Edward from being thrown off a building. While not as strong as his lion form, the owl form helps Edward deal with creatures in the skies with speed and accuracy.

Human...? - A form created by Edward after a mental breakdown against Phillip Lane, leading to the birth of a darker personality of himself. Unstable power and an even more unstable personality, this form by far the dangerous of them all. Edward fears this form...
