SNK vs. Capcom
Guile has a special introduction against Rugal Bernstein, where he cuts a statue of himself in half with a Sonic Boom before Rugal destroys the base with a Reppuuken. This is in reference to The King of Fighters '94, where Rugal has a statue of Guile amongst his various trophies. Given how he makes his "statues", this implies Rugal had fought Guile in their universe and used his body to create his statue.
