Sailor Saturn is much stronger than Sailor Mars, but even she won’t be able to stop Emma Frost. With the Phoenix Force in her position, Emma Frost is a very dangerous weapon in the Marvel Universe. The Phoenix Force grants her great speed and strength, which make it easy for her to take her foes down for the count. Saturn’s raw power appears to be impressive, but I can’t say much for her speed, which is a big weakness. Emma Frost wins.
