Your town theme seems cool !
If you are going Myth based I would recommend you (in addition of the octopi villagers, Drago, Anhka, Julian and Tiansheng) : Phoebe (based on the Phoenix), Hans (based on the Yeti), Roswell (based off of crop circles, patterns in fields often rumored to be related to aliens), Avery (Aztec design, and Aztec mythology is quite rich), Vesta (based on the greek goddess of fire)...
Or you could choose one or two scientific looking villagers, it will go well with the Octopus/Lovecraft idea, like Petri or Raddle !
Last idea is to take all robotic villagers alongside Cephalobot so Sprocket, Ribbot and Del.
Yeah your theme inspires me
Thank you for these suggestions. I might also consider Shino who appears to be based on a demon.
Funny thing, I did have Ribbot and Sprocket on my island at one time. I currently also have Coco whose appearance appears to be gyroid-like.
