Darth Sidious (ROTJ) vs Obi-Wan Kenobi (ANH), Yoda (ESB), Luke Skywalker (ROTJ)

Canon only.

Legends Sidious would utterly stomp, but Canon only I'll bet on the team tbh.

Team comfortably.

Ghost Yoda via lightning.

Obi-Wan or Yoda solos.

Sidious wins if its ESB Yoda

Luke solos.

Team comfortably
