Ell Blue has many of Leona's Heidern's normals, and he is pretty damn good because Leona has damn good normals to begin with but he could hitconfirm them into pretty great damage.
Brazel is more like Chris, and Brazel is the last boss with a super form, which is parallel with Orochi Chris, and he also is the host for Orochi in KOF.
Claire is very similar to Kula with the ice powers.
Ruriy isn't anything like Ingrid though, they don't really share any moves or stance. Ruriy always had the Juri face to me, but she plays pretty unique to herself imo.
Legend is close to Akuma in likeness and has Ryo's air kicks. His moves look different than Akuma's but their function is very "shoto-like".
Shirley is a female Goenitz pretty much, which is funny because in MUGEN people made a female Goenitz called Goeniko.
Sheva is really a gay Benimaru (yea Beni is straight) in playstyle. He's way more flamboyant and really does play up the camp gay theme.
All the characters aren't 1 to 1 matches though, there are many differences between the characters and the fighters they are based off of.
