I liked the head of the set when they first came out, so I used that. Then came up with a functional frame.
About this creation
Most Drones are mass produced and have similar coppied AIs. They are also uses as programs for all machines by the use of the AI crystal. They can be programmed to use any kind of weaponry not just they're own.
They also serve as handy Krana carriers with these holders on their back in credit of the early years.
