I'm talking about this weird s*** introduced in MKX where he apparently now has some kind of mysterious hidden power and passed it on to Cassie. I don't even have much to say on it other than pointing out how strange it is. Like what's the deal? A lot of things in the previous two MKs feel out of place but this is weird in a different way because it took something that was easy to just let exist as a normal component of Johnny Cage's fight mechanics--the green fireballs and shadow trails--and suddenly made it special among all the other crazy powers on display in the franchise. He was cool as a Hollywood martial artist who got caught up in an interdimensional tournament and managed to hold his own. Now he's like a shonen protagonist drawing on a well of hidden potential to save the day.
It wasn't really a "normal" component, so they just ran with it.
It is in the context of MK. Sonya sets people on fire by blowing a kiss, Liu Kang throws fireballs, Kabal runs around like the Flash. But Johnny Cage is special?
