Legends Grievous is almost an unstoppable monster, but that’s not the angle Lucas was really going for with him.

In the Revenge of the Sith director’s commentary, he says:“With General Grievous, I wanted somebody who was reminiscent again… of what Anakin is going to become, which is a half man, half robot. In this case, Grievous is sort of 20% alien and 80% robot. […] It echoes what is about to occur with Anakin as a part machine, part life-form.”“One of the big issues behind Grievous was that… I didn't want a big  powerful villain. I wanted a cunning, you know, almost cowardly villain  who isn't super-strong or super-powerful, but at the same time, you  know, is a good fighter, but not- I didn't wanna get somebody bigger and  stronger and more powerful than the other villains that we've had,  going to the next level. I wanted him to be slightly more like the  emperor. Slightly more on the sleazy, behind-the-scenes kind of guy.  That's why I set up the fact that he always runs at the end of every  fight- he always gets away.”He wasn't nerfed in Clone Wars or Revenge of the Sith, like many people believe. Also, in a BTS video, Dave Filoni said that - according to Lucas - Grievous wanted to be a Jedi, but wasn’t Force-sensitive, so he spent his life improving on himself, trying to become the ultimate response to the Jedi, in battle. The more he fought, the more he upgraded himself, till there was nothing left. He’s motivated by jealousy. He doesn’t collect those lightsabers as some messed up way to honor his fallen opponents, he’s showing them off as trophies because “fuck those space wizards, how’d you like me now?” lol via /r/StarWars https://ift.tt/LNCK97P
