[quote=@Lmpkio]I've mentioned this before, but while I do prefer titan-sized monsters for this arc, I don't mind maybe one or two parastic monsters depending on what they do. Like one example of existing parastical kaiju at the titan-sized monsters are the MUTOs from Godzilla 2014, who lay eggs inside their monsterous hosts or what not. 

Crazier stuff can occur in future arcs and side-quests will be a thing in all arcs. Just show me what you have in mind and I'll see if it's good or not.[/quote]

Well I don't have a pic chosen yet, still looking for a suitable one, but I was thinking something similar to a Neurax Worm from Plague Inc, but without mind control if that doesn't fit, which hijacks a human host and uses it to interact with the world at large. It could possibly jump from host to host when it's current one is close to death or can no longer keep the parasite alive. Still deciding on a transmission system though. I'm thinking either bodily fluid or burrowing of some kind.
