Slugterra - OC Week - Day 2 - Brothers Blakk

Day 2: Strengths and weaknesses when it comes to dueling? Maybe even just some general flaws and positives about them?

Xerxes:

On Dueling:
-Like his father before him, Xerxes is a very proficient dueler. His use of The Twins with their extended magazines helps him easily replicate the rapid-fire function of the Harbinger, without all the bulk of his father's infamously monstrous Blaster.
-He's tried once to use a modified Gatler, but learned that the sheer amount of power behind the thing was built more for Ghouls [even as a converted weapon] as opposed to the standard Slugs. Through it, he also discovered he's not as sturdy as he originally thought when the repeated recoil knocked him clean over. While the Gatler could easily make him more formidible, he simply does not have the bulk nor the arsenal to weild the thing at full power.
-When something happens and he has no use of his Twins, he is still pretty proficient in physical combat.
-He's also an easier target when this happens, seeing as how he's not as proficient as he should be and is, therefore, a klutz in anything more advanced than passed what his mother's taught him.

In General:
-Xerxes is brilliant. A mechanical engineer, genius, and more than enough ambitious and determined to keep the company going.
-He's also charismatic and uses that to his advantage to manipulate people to do his bidding; rarely does he actually do any fighting against the current Shane, he prefers to play the 'victim' card and get entire caverns to do it for him. Willingly.
-He's full of himself though, and very arrogant. Very cocky, something that undoubtedly comes from his youth.
-He's also scatter-brained and doesn't tend to think too linearly when it counts most.

Marius:

On Dueling:
-Marius, unlike his brother and father, doesn't sling very much. He still carries a small, high-intensity one-shot Blaster on his person in case he may need it, but he rarely does.
-He is most proficient in physical combat, generally using Xerxes and his highly-refined slinging as coverfire to get in close.
-He redefines 'Bringing a knife to a gunfight' and generally leaves no survivors if he can get in close. Which is most of the time.
-He also redefines the occasional 'Coming back in pieces' when things go south.

In General:
-Marius is his own brand of brilliant. Whereas his brother thinks in numbers and equations, Marius thinks in probabilities, linear tactics, and strategies, even on the fly in split seconds.
-He also has this weird ability to predict exactly what's going to happen if things keep going the way they are at the time.
-He's incredibly reserved. Like, ridiculously. He doesn't show emotion, feel emotion .... basically deadpan most of the time. This is for good reason, but pushes away a lot of people. As a result, his social standings are pretty much nil.
-Ghoulshifter. 'Nuff said. It can be its own strength, but given that the Dark Water in his very being is slowly corrupting him even when he's not Shifted, it's more a weakness than a strength in the long run.
