Stomer Thomson is a pilot for the Vanguard 7CB. He joined fairly recently, within the past few months, and has yet to be promoted. While Thomson was blessed with a natural affinity for piloting, nature cursed him in another manner, he stammers, a lot. He also has a very strange obsession with his mother, and tends to speak about her, in his stammer, to no end. Now that his mother has died, he speaks primarily on how she was killed by the Phyrrians. He pilots the Claymore 5. He is commonly called 'Stoner' by his fellow pilots, and while he doesn't show it, it does become evident that over time he truly does dislike his nickname.
