Galen Marek VS Kyle Katarn

BIOGRAPHY'S
The future battle-master of the new Jedi order, Kyle Katarn began his carrier as a Rebel mercenary.  Eventually, Katarn would defeat the dark Jedi Jerec and realize his force potential with training from Jedi master Luke Skywalker. Katarn would go on to fight during the Mako Ragnoss crisis, the Yuuzhan vong war and the second galactic civil war, gaining him a seat on the council and a legendary reputation.

The son of two rouge Jedi knights, Galen Marek was discovered to be a powerful force sensitive at a very young age. Unfortunately for him, he was born under the rule of the Empire and taken under Darth Vader's wing. Trained as his secret apprentice, Galen Marek was first tasked with hunting down Jedi survivors, before Vader used him to draw out the leaders of the fledgling Rebels. Angered by the betrayal, Galen Marek bid goodbye to his allies and left for a final confrontation with Sidious and Vader, and battle that ended with his death.
INTRODUCTION
Greetings viewers and fellow Imperial knights! This is Hondo Moonrazor here with a match up that has been suggested by both Darth Judicar and Wolf Myth, Galen Marek vs Kyle Katarn. True, I have done something like this before, but it was in a group battle and involved Lord Starkiller, whereas this is a straight up battle between Katarn and the original Galen Marek. So lets jump in and see which video game Jedi wins the day!
MARTIAL ARTS
Although originally apprehensive about using his lightsaber and force ability's, Kyle Katarn eventually embraced his Jedi heritage. Although mostly self trained, Katarn is described as a master of Dejem So, giving him a strong and powerful fighting form. Katarns natural skill with the blade was such that, with very little training, he defeated seven dark Jedi in a row, ending with Jerec, one of the Empires top enforcers. Later in life, Katarn became the battle master for the new Jedi order, responsible for the training and combat instruction of almost all new initiates. Katarn also had a hand in the creation of the new Jedi orders lightsaber forms, even though these were largely replaced with the seven classic forms. During the second galactic civil war, Katarn again proved his martial skill when he engaged Darth Caedues. Katarn managed to match Caedues'es speed and was only truly defeated when he opened his defenses in order to save one of his allies. In the end, Katarn defiantly earned the title of Battle Master, with both Luke and Caedues acknowledging his skill.

Trained by Vader to kill Jedi, Galen Marek was a powerful force user and skilled duelist. Left to develop his skills mostly by himself, Galen Marek became a user of both Soresu and Juyo, creating a strong defense and wild offense. His main form however, was Shien, with power attacks, blast deflection and a reverse grip on his lightsaber featuring heavily in his fighting style. Galens upbringing also involved constant battles with the training droid PROXY, which contained the dueling programs from most of the greatest duelists of the time. Galen Marek was an extremely advanced and varied duelist, overpowering Kazdin Paratus and Marriss Brode, while outlasting and exhausting Rham Kota. His most impressive Jedi defeat however, was the defeat of Jedi master Shaak Ti, matching her with both the blade and force. Galens final battle was against his former master, Darth Vader, in a pitched battle aboard the Death Star. Although the two were closely matched in terms of martial arts, Galen eventually overwhelmed him with the force. In the end, Galen would present a challenge to almost any Jedi.

Although both of these are dedicated power duelists, Galen has more diversity and skills under his belt. True, Katarn has matched top tier duelists before, but Galen has shown many and diverse tactics to take down different duelists, as well as a batter mastery of different forms. Galen Marek gets the martial arts edge.
FORCE POWERS
Unlike most Jedi, especially ones who has had previous problems with the Dark side before, Kyle Katarn openly used both the Light and Dark sides of the force. This allowed him to be proficient in a wider variety of powers, from force Lighting to Absorb. He was also skilled with more mundane abilities such as telekinesis and self augmentation.

Galen Marek was an EXTREMELY powerful force user, with a raw and primal connection to it. He could kill people with a single blast of lighting, weaponized the mind trick, could destroy armored vehicles and absorbed even Palpatines lighting. However, as with most Imperial Knights, I believe his ability to take down star destroyers and nuke stormtroopers are just artistic license.

Sadly, I dont think theres much of a contest here. True, Katarn is a powerful force user, but Galen can match everything he has, but with more magnitude.Although I don't think Galens mind trick will work against a force user, but his telekinesis is more powerful, if not more refined. The deciding factor in this category if force Lighting and absorb: Basically, Galen can nullify Katarns energy attacks almost completely, I don't think Katarn can quite hold off Galens deadly lighting. Galen gets the edge in force powers.
PHYSICAL SKILL & EQUIPMENT
The remaining two edges are minor enough, I am just going to address them both here: Galen is much younger and, due to his brutal training, much physically stronger than Katarn, Whereas Katarn is armed not only with his standard blue bladed lightsaber, but with his light armor and blasters as opposed to Galens simple red blade. This being said, Katarn is still in great condition and can augment himself through the force, and Galen is an absolute master at blast deflection, not to mention the fact that Katarn doesn't seem to use his blasters in single combat. In short, Galen gets the physical edge, Katarn gets the equipment edge, and neither really matter.
THE VERDICT
A battle between these two would be a relatively basic duel. They are both dedicated power duelists, although Galen is more varied and could switch to a different style if need be. In the end however, this battle will be decided by there force powers. Galens overwhelming strength in this area would give him a clear advantage, and even if Katarn manages to match his martial skill, he cant hope to stand for very long against Galens force powers. In the end, it would have a similar result to Galens duel against Rham Kota: he would allow the older Jedi to exhaust himself and then finish him off with a mighty display of force powers (Yes, I know thats not what happened with Kota, I was just using it as an example). Thus, I declare Galen Marek, Vaders secret apprentice,  the winner.
