Commander of the Seventh Flame – Greed, Dynamite

Description
“One greedy prick” is how a lot of people would describe him; Grim only seems to want more and more money, women, and fame, by any means necessary. He will not hesitate to steal or murder someone if he thinks it could serve his desires.
With his psychopathic tendencies and unquenchable greed, Grim is always in the middle of trouble, one form or another. He is also a massive joker and prankster, and loves taking things too far just to see how people react.
He is also extremely emotionally volatile, seemingly exploding out of nowhere. Because of this, he has earned the nickname; Dynamite.
On the battlefield, Grim takes things a notch too far, often ending up having to be hospitalized for mana overload. He becomes enraged when hit, and is extremely brutal, even when unarmed.
Backstory
After being sentenced to death for killing over a dozen guards and stealing a gemstone worth 10 ALU, Qune Astra gave him a choice; give his life to the Kaligo Empire by enlisting in the army, or be executed on the spot.
Grim chose the former, and enlisted into the infantry unit of the Seventh Flame. Because of his brutality and fighting skill, he was quickly promoted to a Chosen Warrior.
As a Chosen Warrior, he frequently had missions together with the other squads, during which he became buddies with Kiryu and Obsidian, forming an almost brotherly connection to them.
Once the previous Commander was killed, Grim took the title of Commander of the Seventh Flame.
As Commanders, Grim continued to fight side-by-side with Obsidian and Kiryu, developing an even tighter bond in the process as they survived some of the most crucial and dangerous missions possible.
When Kiryu was announced dead, Grim and Obsidian took it up as their mission to avenge Kiryu’s death, to kill the Royal Wizard Kline Snowden.
Even though Grim is usually quite neutral with death, it seems that Kiryu’s “death” hit him harder than even he expected. Weeks after learning of his supposed death, Grim trained so hard that he had to be hospitalized for severe mana overload, almost dying in the process.
Special attributes, items
Grim has an exceptionally high magical potential, which he uses quite recklessly to create explosions out of fire magic, capable of easily destroying gates, even small walls with the force of multiple battering rams.
Misc information
Grim is extremely insecure on the inside, which partly explains his excessive need to show off. He is extra paranoid and nervous, always sure he could be betrayed any minute.
Grim absolutely loves gambling and alcohol, often neglecting his responsibilities as Commander because he is drunk somewhere in a stable or a maidens house.
Like Kiryu (when he was a Commander) and Obsidian, Grim talks in a highly crude and vulgar way, quite possible even more crude than his two friends. He swears and talks casually to the royals of the Kaligo Empire, and even to the Emperor himself, which has earned him trouble more than a few times.
Grim appears quite hard on the outside, but in reality, he is quite soft, often crying when he is alone, thinking about life, such as when Kiryu passed away.
Grim could be classified as having some form of either borderline personality disorder, or psychopathy; maybe even a touch of both.
