Ike is the son of Commander Greil; the founder of the Greil Mercenaries. Ultimately, Greil was mortally wounded by the "Black Knight" which forced Ike to take command of the units. Ike started out with the title of Ranger, but was eventually granted the title of Lord by Princess Elincia when he lead the Crimean Liberation Army as its general. He has been granted the title of Blitzer for his duties in the league of FUMBBL. Ike has quickly adapted to the fundamentals of Blood Bowl, and is already being considered by many to be a Professional.

The most fickle and critical in the Mercenaries are Gatrie and Shinon. Gatrie's main focus in life is women; this often impacts the decisions he makes. Gatrie took on the job of being the bodyguard for the Begnion noble Astrid. After resisting a Daein onslaught, he later rejoined the Greil Mercenaries. His size, strength, and defense are what make him most worthy of the Ogre class. Gatrie's put in months and months of weight training since he began playing Blood Bowl. He was quoted as saying after match #17: "I feel like I can take on the world! I have never been in better shape in my entire life."

The most fickle and critical in the Mercenaries are Shinon and Gatrie. Shinon regularly belittles Ike and finds it insufferable that he should be under the command of the young soldier. He seeks more challenging and prestigious opportunities for Greil's Mercenaries, who only do minor jobs. After a brief stint with the Daein army, he begrudgingly rejoined the Mercenaries after learning that Ike had grown stronger and after his student, Rolf, persuaded him. Shinon's skill with the bow is impeccable. No-one is more fitted to be a Thrower than Shinon.

Rolf is the youngest and initially the weakest of the three brothers- Oscar, Boyd & himself. He shares a friendship with Mist, who is of a similar age to him. He was taught how to use a bow by the Sniper, Shinon, during which time he developed a friendship with him. Despite still being young at heart, he becomes an accomplished Archer. Rolf should make a very reliable Thrower, as he almost never misses his target.

Titania is the Deputy-Commander of the Mercenaries; she is an ex-Crimean knight, and met Greil in Gallia while training as a knight. She was deeply affected by Greil's death—Ike suspects that she may have had romantic feelings for Greil. She was named Catcher for the team as was Oscar for their unmatched movement ability. Titania has absolutely no fear in the game of Blood Bowl, she is willing to face-off against the toughest of opponents. Titania picked up an injury in training which has reduced her ability to compete in every game for the Mercenaries. This angers Titania, who swears that when she does play, she will be enraged towards any and all of the oppostion she faces.

Within the Mercenaries are three brothers, Boyd, Oscar and Rolf. The oldest, Oscar, takes the most responsibility amongst the siblings. Before joining Greil, he became a Crimean Knight so that he could earn enough money to look after his two brothers. Next to Ike, Oscar may well be the most loyal soldier of the Greil Mercenaries. He was named Catcher for the team as was Titania for their unmatched movement ability. Oscar has absolutely no fear in the game of Blood Bowl, he is willing to face-off against the toughest of opponents. Oscar's horse is the fastest horse in all of Gallia.

Boyd is a headstrong fighter who shares an amicable rivalry with Ike. Like Oscar, he too tries to support Rolf.

Mia is the newest member of the Greil Mercenaries. She learned some of her sword fighting skills from Ike.

The staff officer and strategist of the Mercenaries is Soren. It has been revealed that Soren is the son of the late King Ashnard and is the true Prince of Daein.

Rhys is the primary healer in the Greil Mercenaries.

Mist is Ike's sister and the holder of Lehran's medallion (the Fire Emblem).

*Intercepted, Blitzed & Scored the game winner in turn 8 of match #17.

Reyson is the prince of the fallen kingdom of Serenes, and one of the few herons that survived the Serenes Massacre. Reyson is no stranger to the Greil Mercenaries, he has lended them his aid in many battles and together they have had many victories. Reyson is not a Mercenary, but is a welcome addition to the team and is quite comfortable with playing the back-up role. He will be called upon when needed.

Pelleas is believed to be the son of Ashnard and the Prince of Daein. However, he is not the true Prince: he is merely a spirit charmer who was tricked by Izuka into believing that he was royalty. (The true Prince, is later revealed to be Soren.) Pelleas has watched every game the Mercenaries have played and has taken a liking to the game of Blood Bowl. With his royalty proving to be a hoax, he has taken the belief that everyone should be treated equally and he considers himself as fodder as the Lineman next to him. Pelleas submitted a request to Ike for his services in joining the team, of which Ike graciously accepted.
