Question: Why does Edison become Krall? In other words: why does his appearance change? If the tech that keeps him alive changes him, how can he change (most of the way) back? Finally, if he could change back/remain human this whole time, why would he look like he did?

Answer: The energy transference technology Krall used to drain the life of others caused him to gradually begin to look like the species he was draining. After the attack on the Enterprise he drained several human officers and began to look like his former self.
