Which of these is the most physically perplexing?

We all know chronodia is based off the appearance of the combined seven heroes from Romancing saga 2.

Anyhow, my pick would be Neo Exdeath. Pretty much the backstory of Exdeath states he was a tree in the forest of moore which many demons and monsters were sealed in, and the tree apparently became Exdeath as a result of all those monsters sealed in the tree. Pretty much Neo Exdeath is what appears to be the legion of demons and monsters that became Exdeath in the first place. Whats more interesting is that there is no beginning of Neo Exdeath and who knows how truly large Neo Exdeath is. I also remember once seeing a fan made image of Neo Exdeath on devianart and I must say its a very creative design that has a very different angle of view.
