Question: why kylo ren is so weak?
Answer: Kylo Ren seems weak because he is undertrained. Before he took up his mantle as the Knight of Ren, Ben Solo was Grand-Master Luke Skywalker's Padawan. ... Soon Leia couldn't raise him but she sensed the Force in him and sent him to Luke, hoping that Luke could train him but also be the father figure that Han wasn't to Ben.
