Less is more, General Grievous
In the movies, General Grievous only wields four lightsabers, but memers couldn’t help add a couple hundred extra arms and lightsabers. As you can see, all that fancy lightsaber twirling ended up pretty badly for him. They say that less is more, General Grievous.
General Grievous was neither Sith nor Jedi, despite being trained in seven forms of lightsaber dueling. In the end, he and Obi-Wan duke it out in a chariot-like battle that causes both of them to fall off of their rides. A few moments later, General Grievous dies not in a lightsaber battle but rather getting shot in the chest by Obi-Wan. “So uncivilized.”
