I'm going to assume you mean the American version of Vega, not the character we know as M. Bison.
Well, Vega lacks a projectile attack, so Liu Kang would of course have an advantage. However, Vega does have air-based attack and MK4 Liu lacks air counters, so Vega could attack while avoiding Liu's fireballs. However, Vega mainly needs to get close to do any real damage, while Liu has distance attacks. The problem here is putting a 2D character against a 3D, but I'd have to say Liu Kang wins this one simply based on his offensive capabilities far surpassing those of Vega.

I wonder if anyone will bother trying to read what this says.
