Darth Nihilus would one-shot Darth Sidious (Palpatine) if he was still alive

Darth nihilus is awesome and better than palpatine

darth nihilus looks scary

He is

i myself don't think the comics canon feel free to disagree

Had to look up darth nihilus, did not find anything pretty

Darth Nihilus could destroy entire planets using the force.

how did he die

basically, he got too much power for him to control and the force killed him.

ok

Yes

Have you ever heard the tragedy of Darth Sideous the Stupid? 😂
