I have reason to believe that the.Tortodrone, if not classified as a Drone, will be a Fiend.
1) Tortodrone bodies are commonly found in Wolver Dens.
2) Devilite scenario rooms have tortodrone bodies and other equipment.
3) Scenario Rooms in Clockwork Tunnels show active Tortodrones and some Gremlins
4) Nick leaked the devs are working on a weapon that will make "devilites quake in fear"
But what does this meeeeeaaaaannnnn? Well, Phreak, it leads me to conclude
1) Tortodrones are preyed on by wolvers, ergo weak to piercing
2) Devilites and Tortodrones are linked
3) Tortodrones are harassing the Gremlins. gremlins are weak to shadow, so....
4) Tortodrones are Fiends.
But I can't be the only one who is theorizing like nuts.
I think its a construct,fiend,gremlin,amd beast or something like vanaduke how he is a fiend but resists everything but normal and piercing
