first saw Shadowgeist, I thought he looked completely out of place for Street
Fighter... and in a way, he is. However, let's not forget about Skullomania.
Shadowgeist seems to be a soft of "arch-enemy" of Skullomania. Whether
or not you think he fits in Street Fighter, he's a cleverly detailed &
original visual design. He also seems to be inspired by the likes of some
characters from Kamen Rider. As an "oddball" character, he definitely
rates high on the obscure meter, which many previous Street Fighter characters
have also been successful with. I personally enjoyed using him in EX2...
he helped make the roster more interesting.
