Three Abilities

Kahn hovered in the air at least 100 meters high in the air while in front of him, was the ginormous figure of Axel who was at least 250 meters tall after he transformed and revealed his true form as a monstrous creature. 

Just now, he figured out the 2nd divine ability Axel had known as Soul Eater. It could allow the user to absorb souls from recently deceased saints to gain an extra life. 

However, the biggest flaw of Soul Eater was that it had the condition of needing a dead saint. Not something you see happening often. This was one of the reasons why Kahn didn't choose it but for Axel… it was the best choice. 

Right now, Kahn's team killed 7 saints from Hero's Party to pressure the Hero of Fire by cornering him with their numbers and forcing his hand to give up the artifact. 

But eventually, because of the Soul Eater ability… he ended up empowering Axel instead. 

And now… Axel finally finished his transformation.
