LyCORIS for the iconic robot R2D2 from Star Wars, made for this bounty. https://civitai.com/bounties/8035/pony-lora-for-r2-d2-from-star-wars-with-added-features

The main trigger word is R2-D2, you also can use r2d2_standard for the standard look.

As requested from the bounty, i put some extra attentions in pictures where his tools and mechanical arms are out, the trigger for that is r2d2_tools.

I also made an attempt to add some pictures from the version showed in the "Edge Ferry Droid Depot" variant, where it has legs and arms. the trigger should be r2d2_edgeferry, but i had very few pictures and i wasn't able to actually make that work in my tests
