AMATERASU

Amaterasu , nicknamed Ammy by Issun, is the main protagonist of Okami. She is also known by villagers in her past life as Shiranui. Amaterasu is the Ōkami, the Sun God to all of Nippon, and the "origin of all that is good and mother to us all". Amaterasu doesn't talk, but she barks every time she attacks in Marvel vs. Capcom 3: Fate of Two Worlds.
Amaterasu, in keeping with her wolf nature, is gentle, loving and utterly loyal to her friends (as shown when she wept with great sorrow in her refusal to let Issun go when she boarded the ark even though she knew well he could not go with her) but is crushing and relentless towards those with evil in their hearts. She at times falls asleep when people have long talks with her and so she may be easily bored. Perhaps due to Issun's encouragement of "Leap before you think.", she may have become more brash when dealing with certain situations.

In Marvel Vs Capcom, She is seen in the Episode 2 trailer aiding Captain America, Chun-Li, Trish and Tron Bonne against Doctor Doom's and Super Skrull's attack on the S.H.I.E.L.D. Helicarrier. She and Viewtiful Joe attack Super Skrull in mid-air by climbing up his flexible arms while Tron distracts him on the ground, but he turns invisible, causing them both to fall towards the Hudson River. Fortunately, they are both saved by the timely arrivals of Iron Man and Morrigan.
