Not sure why I suddenly decided to design my own Digimon, but I've been working on my own giant-isopod themed digivolution line (though as you can see with Limamon here, other deep-sea creatures got added as inspiration too). I used to play a few Digimon games way back when I was a kid and watched some of the animes too. My favourite was Data Squad and my favourite games were Dusk/Dawn.

Limamon
Level: Fresh
Type: Mollusk
Attribute: Data
Family: Deep Savers

A newly hatched Digimon which carries a core so volatile that the majority of them self implode before they are able to digivolve. It is so frail that any combat will destroy it, and it can do little to defend itself except try to intimidate its opponent.
