Yep. My main 'bots MM is a young lady born without an arm... So she built herself one for a school science fair project, and was encouraged to follow that path to help herself and others. But she soon realized that she could do more. So, after licensing her arm for production - she took the license fees and built her 'boys'. Now she splits her time between her lab developing new robotics - and field testing her developments.
Most "I can't RP that" (or "that breaks immersion)" is lack of imagination, not lack of tools in game. I mean, if I (as none of those things) can roleplay a female dwarf cleric <mumble> feet under the North Atlantic on USN submarine...
Not to mention - what the heck is 'heroic" about a plague of insects? You'd have to backstory/head canon/RP those too.
