Cross-posting from the other thread. Its not everything Malgus has done, but its still full of badass:
"Sidious describes Malgus in the Book of Sith as 'an exemplary warrior. His battlefield feats have never been equalled.'
In The Third Lesson while still mortally wounded by Satale Shan in the Hope trailer Malgus fights two Jedi. One of the Jedi collapses two large duracrete buildings on top of Malgus, who holds up the rubble before blasting it away. He engages the Jedi in lightsaber combat before sensing the second whom he kills easily by snapping his neck with the Force. Then the Jedi who collapsed the buildings on him charges, but Malgus blows through his lightsaber defense with his lightning, burning holes in his body with it before executing him.
In Deception Malgus kills 3 Jedi at once with a single burst of lightning. His Force Scream shatters a huge collumn. His Force Push kills a Jedi by blasting her across the temple and is described as powerful enough to splinter bone. He lifted 2 pieces of statuary and smashed them into each other hard enough to shatter them into a shower of stone. He's leaped to the ground from 50 meters up while creating a cocoon of power strong enough so that when he landed he shattered the stone and turned it into a hail of shrapnel. He's incredibly strong, at one point kicking Lord Adraas so hard he flies across a room and cracks a stone column in half and being described as stronger than Aryn Leneer, who herself was able to fling Malgus the length of an F-22 (20 meters). At the end of the novel he completely embraces the Dark Side and gains a massive boost of power making him beyond all the feats I just mentioned.
Finally in TOR Malgus fights either the Strike Team made up of the Republic or Empire players. Despite fighting such opponents as the Hero of Tython + Barsen'thor/Darth Nox + Emperor's Wrath he is able to bring them to their knees with a gout of lightning and toss them around in TK. "
