I've decided to move away from the KotOR era, and I'm slowly moving into the TOR era now. I'm deciding to create respect threads for the protagonist characters with whatever canon material I can find which obviously includes game cutscenes and sourcebook entries (the only one at the moment is the TOR encyclopedia, to my knowledge).

Note: I will be using feats from the trailer, which I deem as likely canonical enough. If you disagree, that's fine, but I do think the feats from the Jedi Knight trailer should be made available.

With that out of the way, respect the Hero of Tython:

Power

Few enemies can match the Knight's raw power once he is trained:

Bengal Morr claims that the Knight is stronger than any Jedi he has ever known:

“You are stronger than any Jedi I have known.”

The Sith Lord Praven senses the Knight's power and skill, commending it as "impressive" and claiming that he understands why Tarnis was no match for him:

“I sense your power. Now I understand why Tarnis was no match for you..... Such skill. So much power. Impressive.”

The Force is stronger in the Knight than any other Force-user Orgus Din has seen in decades:

“The Force is strong in you. Stronger than I've seen in decades.”

Scourge believes the Hero is the finest Jedi:

Even when disarmed, the Knight is a significant threat on the battlefield because of their mastery of the Force:

Even Knights who lose their lightsaber remain significant threats on the battlefield thanks to their mastery of the Force.

The Sith Emperor himself acknowledges the Knight as harnessing "immense power", despite being on a potent dark side nexus which would have weakened the Knight considerably:

"You harness immense power."

Force Valor/Protection/Speed

Force Valor is a light-sided power enabling a Jedi to enhance one's resolve and physical traits, such as strength, durability and speed. Force Protection is the passive (and sometimes active) enhancement of a Force sensitive's durability to varying superhuman degrees. Force Speed is the passive (and sometimes active) enhancement of a Force sensitive's speed to varying superhuman degrees.

Note: I know this only happens in the dark side version, which is presumably non-canon, although there has been no official declaration of which side is canon first. And I stand by what I have said before - that even if he didn't actually do this, the feat should at least prove he is capable of doing so.

Telepathy

The Jedi Knight displays a Mind Trick on Sith Overseer Chaskar, convincing him to leave the scene:

Combat Skill

The Knight's unrivaled physical precision and reflexes, when combined with the Force's precognitive aspects, enables them to turn combat into an art form, gracefully executing elegant lightsaber tactics and acrobatic feats

Through years of disciplined training and meditation, the Jedi Knight hones body and mind into perfect harmony. Combining the foresight of the Force with unrivaled reflexes and practiced physical precision, the Knight turns combat into an art form, gracefully executing acrobatic feats in tandem with elegant lightsaber tactics.

The Knight possesses dazzling combat skills, and is capable of achieving extraordinary feats:

The Jedi Knight’s graceful movements are awesome to behold. Freezing a moment in this display captures the deep commitment underlying the Jedi’s dazzling abilities. Though a Jedi Knight’s life is filled with battle and adventure, the Knight’s heart is dedicated to peace and service. An ironic observation to some, but greater wisdom suggests it is the Jedi Knights’ humble devotion which makes them so likely to become such famous heroes.

Whether defending allies by deflecting a barrage of blaster-fire or charging in to challenge a Sith Lord, the Knight’s role is crucial in any conflict. The Jedi Knight enjoys the benefit of ancient teachings that have been passed down through hundreds of generations. Combining these time-tested maneuvers with the natural guidance of the Force, the Knight is capable of achieving extraordinary feats.

With only a training saber and still a padawan, the Knight defeats Bengel Morr, the lightsaber wielding former apprentice of Orgus Din. After constructing his lightsaber, the Knight then defeats a jurgoran:

Defeating Lord Scourge in single combat, with Scourge being the Emperor's Wrath and has centuries of experience and practice following his appearance in the Revan novel, by which time he was already skilful enough to beat a pair of amped Imperial Guards in a few seconds, match Meetra Surik in lightsaber combat, and whom as a student was already more than a match for his Sith instructors:

Defeating the Emperor Lord Vitiate himself, after fighting through numerous troops. The Emperor was severely weakened, but was also in the Dark Temple, a very powerful dark side nexus, as well as on Dromund Kaas, which itself is a dark side nexus. This would have partially compensated for the Emperor's loss of strength, and would have additionally served to hinder the Knight considerably:
