Well Raiden did defeat Liu Kang, so...

And funny enough, I think the dragon is one of the main things that'll keep Liu Kang from Death Battle for a while. It's an iconic part of him, so they'd have to include it, but there's been no record of any limits or weaknesses of it. Not to say Ryu can shoryuken its head off, but unless it isn't totally invincible, why doesn't Liu Kang use it before his fights?
