I heard alot of people saying that they think Philip Wittebame is Belos. However i had a different though what if Belos actually IS an abomination!

Maybe Belos was an abomination created by Philip or one of his descendents to protect/guide his family after his death, but at some point Belos went rogue maybe he got possessed by the titan, he and Philip also kind of sound alike maybe he has a part of his soul or something. Or if we go really dark he could just be such a long living abomination that he eventually achieved self awareness and started consuming palisman to gain magic.

Now some may be thinking "but hunter called him uncle" an uncle doesn't actually have to be family member, in many cases, it could just be a very close family friend and an immortal abomination that's always there for the family would hold that status i believe.
