Chun-Li has had several ways to confuse her opponent by crossing over and under them in Street Fighter V. Let’s just add another possibility to do so to the list, shall we?
While we have known she can cross under after an anti-air, and can cross over their knocked-down bodies with forward roundhouse, a setup to do so has been found with light Spinning Bird Kick. While this is entirely situational–requiring not only V-Trigger, but scoring a crush counter with back fierce–by timing your SBK properly, you can either cross over or stay on the same side of a quick rising opponent. This puts them into a 50/50 mixup that can deal a mass amount of damage.
