The question is, does Kirby's power go beyond one generation of absorption. He tends to gain, essentially, a tl;dr version of his victim's powers- he doesn't gain everything about them, just one crucial characteristic. So probably, he would gain the ability to absorb powers when he killed his enemies, not just when he ate them. Shang Tsung's powers would be lost in the mix. (Overly logical analysis)

But Six, you missed something! It was established in Kirby Crystal Shards that if Kirby takes in two different beasties it gets a fusion power. I'd say that this probably falls under that, so Kirby would get a single power representing both.

I think you're missing the point guys. XD
