There were several reasons for why Unbreakable was asking Skullius for help.
This might have seemed contradictory when considering he could see the Penetrator's appearance from where he had torn off the side of the creature's helmet but the man had considered a lot of things since that moment.
One was that Skullius didn't emit any evil presence. Heck, the bastard didn't even have a presence to begin with. It was as if he wasn't there when he used the senses outside his sight.
Of course this could be debunked easily but it wasn't the only thing. The skeleton had Levin running along his bony body, which he saw as lightning, something he couldn't exactly tie to undead as he knew them.
The last thing was that this skeleton had actually helped in saving the city with that lightning move that obliterated two chunks of the massive island.
