[@Herald] My concept for Mercy was that he is kind of like an insatiable void / dinosaur in the sense that he keeps getting bigger and bigger, and thus, he needs more and more to sustain himself, but finds it harder to hunt due to his size and increasing need. Which is why he needs Val as much as Val needs him. I'll say that he can't turn smaller, but he can help in situations where he can't materialize by obnoxiously coaching / bickering with Val internally [s](kinda like Venom lmao)[/s]. I have, like, a small hope that he eventually becomes some weird mentor figure who inadvertently helps your guy grow and heal, despite all his murderous energy and evil tendencies haha!

Kaiju battle sounds like a blast! I'm also curious to know the serpent's motivations.
