Rogue Galaxy: Seed

Seed is an artificial human created by Daytron whose soul purpose is to open the gate to Eden. He is a recurring antagonist in Rogue Galaxy that believes himself to be the "son" of Valkog (occasionally referring to Valkog as "father" among all things), he's first shown wearing a mask since his face "wasn't ready" yet. Valkog sends him to destroy Jaster and the crew. He was primarily made to open the gates of Eden but fails and is discarded by Valkog, only for Seed to go insane and transform to a giant four legged beast. He's soon ultimately defeated by Jaster, telling Jaster that all he wanted was to be human like him, and after said so he falls an disappear in a pile of dust. 

Personality

Seed is the opposite of Jaster, he is always calm and sure of himself, and this often leads him to overestimate himself. His greatest desire is to satisfy his "father" Valkog and to become a "real" human like Jaster  and his friend.

Appearance

Also like Jaster, Seed have a unique birthmark on the left side of his face. He has silver hair and eyes. He always wears a black and white suit, and he's first shown wearing an expressionless black and white mask. The reason Seed looks as he does is due to the genetic code found on the great tablet, which was a code resembling that of the Star King's power. Thus the reason for the mark on Seed's face.

Trivia

The final boss in the Ghost Ship, Doppelganger, strongly resembles Seed but looks as if he's in "Star King mode" like Jaster.

Rogue Galaxy: Valkog Drazer

Daytron Corporation president Valkog Drazer is a major antagonist in Rogue Galaxy whose primary concern is profiteering from the intergalactic war between the Longardian Federation and the Draxilian Empire. 

Personality

Valkog is about as pompous and self-absorbed as one can get. He is a living manifestation of Pride, Greed and Gluttony and it shows in his appearance and mannerisms. He cares nothing for the people harmed in the war, nor does he care about whether or not the war is actually accomplishing anything. The way he sees it, as long as he can turn a profit in the end, he could care less if he ran the entire Wilherser system into the proverbial ground.

Appearance

Valkog is a short, devil-looking man with blonde hair, shifty eyes and a Hitler-style Toothbrush Mustache. He wears an expensive-looking robe and several rings. He can often be seen being driven around in a large black limo by his assistant Norma with his associate Dr. Izel. Together, they make up the top ranks of the Daytron Corporation.

*Spoilers Alert*

After the defeat of Seed, Valkog's - and, indeed, the Daytron Corporation's - ultimate goal is to seek out Eden in order to tap into the nearly limitless powers of Rune and create an army of monsters with which to flood the vast reaches of the galaxy and thus prolong the intergalactic war, theoretically maximizing his possible profits from it. He succeeds, though it is a hollow victory indeed as the masterless Rune power snags his ship and drags he and his associates and henchmen down into it. The dark powers of the Rune mutate all of them together to create the Demon Battleship, the final boss of the game. The Demon Battleship (and thus Valkog as well) is killed by Jaster and the Dorgengoa Pirates when their attacks weaken its body to the point that, as Zegram points out, the ship's engine explodes. This effectively finishes off Valkog and company once and for all.

Trivia

* When battling Valkog's hands on the Demon Battleship Valkog will yell in pain as soon as you defeat one of the hands why the hands were inside the batlle ship instead of on the outside like Norma and Izel's is hard to guess

* While he actually fantisises to be the galactic emporer he does have more power than anyone in Longardia or Draxil

Rogue Galaxy: Monsha

Monsha is the first mate of the Dorgenark and the second in command after Dorgengoa. He's very loyal to Dorgengoa, and when the captain is napping or is not around he is the one in charge and often takes advantage. Nevertheless he a good person who care about his crew. 

Personality

He is a bit greedy but offers his help when Jaster and the crew need it. For example he help Jaster and Kisala to return to Salgin when Valkog attacks the city.

Appearance

Monsha appear like a cat with a white fur and blue eyes that wear a collar with a bell.
