first saw Shadowgeist, I thought he looked completely out of place for Street
Fighter... and in a way, he is. However, lest we forget about Skullomania.
Shadowgeist seems to be a sort of "arch-enemy" of Skullo. Whether
or not you think he fits in Street Fighter, he's a cleverly detailed &
original visual design - inspired by the likes of
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.
Weirdly, Shadowgeist shares some moveset similarities with Urien.
Mostly his stance and key shoulder attack. Urien and Shadowgeist also debuted
within a year of each other (1997-1998), which is interesting... I wonder if this
was intended in any way.
