I can't say I see the sense in any of those special infected, save for Alice being the Witch.

Yuugi is extra strong since she's an Oni.
Ex-Keine likes to pounce on and cave people.
Nitori is usually shown with long robo-arm/tentacles.

The only one for me that I can't understand is China as a Boomer.

Letty should be the Boomer.

Boomer=sloth
Sloth=China.

Boomer isn't sloth. Boomer is the one with initiative. His ambush blow leaves the survivors vulnerable to the other infected.

At the cost of then kamikaze himself ie. basically canon fodder...which is a since is what China is. The tackling dummy, so the people inside the mansion won't have to waste time with the common people (ie. anyone who isn't Marisa or Reimu).

Marisa has startled the witch!
