Grimm Wilds, week before Colt's return...

All he could hear was the sound of his breathing, slightly labored as he ran through the forest, that and the howls of the horde of Grimm behind him. Shadowed Peak always was a magnet for Grimm. He turned and fired his AR-15, the bullets taking out a Beowolf as he jumped over a fallen log.

"I told you we should have left before nightfall!" He heard a man growl through his earpiece, and the boy sighed.

"I needed to collect the rest of my equipment and records, Church!" He protested, then hit the dirt and rolled under a huge trunk of a fallen tree, the fastest route a space underneath. The wolf accompanying him crawled through while the teen fired at the approaching Grimm, then the two ran together, hoping to reach the human's minefield and prep it in time to escape.

Please tell me we're close! Summit whined, leaping over a root and dodging an Ursa's swipe.

"We are." Colt assured, though his breath was labored. He whirled again and drew an explosive throwing knife, one of his self-made weapons with duct-tape and an IED. The weapons collided with a Deathstalker's leg, the explosions blowing it off course for precious seconds.

In his ear, Church continued to rant. "Oh, yeah, well we could've stayed in San Rojeros for the night, but no, you wanted to hurry up and get back to your midget girlfriend!"

"Hey, she's not that small!" The teen protested as he rolled from jumping off a short drop, quickly dashing into a grove of trees that all were carved with a tribal flame and the number 27 underneath. "Besides, that's not the-"

"Like hell it isn't, Colt!" Church protested as the Wildsman raised his gauntlet, pressing a button as he cleared the trees. Automated turrets activated and lifted to aim at the Grimm, the death rattle of the guns cutting through the woods as Colt and Summit arrived in the minefield, once again marked by the trees by tribal flame and the number 12 underneath. The minefield was the final stretch to the base of the mountain, one of five around the range, of which only four remained. He also had charges set all over the mountain that could be prepped in sections farther up the range, which he had used for his previous escape.

Colt sprinted forward, leaping above fallen trees and preparing to arm the mines. As soon as he rolled into the clearing, where his horse, Midnight, stood waiting, he clicked the button, and seconds later the explosions rocked the air and cries of dying Grimm resounded through the valley as the Wildsman planted a foot in the stirrup and swinging up and over.

"Now, how do you plan on getting rid of the Nevermores and Griffons now on your tail?" Church asked cynically.

"Oh, I have a few things in store." Colt answered, and with that, he urged Midnight forward, the black stallion galloping forward with Summit hot on his heels.

They rushed down the mountain along an old dirt path that winded down until they cleared the trees, then Colt looked back to see the two Nevermores and dozen griffons following him.

"Oh, that's an easy fix!" He told Church, then slid a pole from his back, expanding it into bow form and drawing three arrows from his quiver, then attached remote-detonated charges to each shaft before taking aim. "Alright, Midnight. Keep it steady."

And then he nocked the arrow and pulled back, waiting until Midnight gave him the best, clean shot, and fired the first, immediately prepping the next arrow and a second later, he released the second, then the third before pressing a button on his gauntlet. The charges exploded in the cluster of Griffons and another on a Nevermores head, having landed right in its neck. The third exploded just in front of the second Nevermore, but it was thrown off its path as Colt fired more Blackshaft arrows into the two giants, the first going down with another two arrows, dissipating as it fell, and the second went for what seemed like a dive for Colt, but bit the dirt just behind Midnight.

The horse whinnied in protest, and Colt returned the bow to its place before drawing his Deagle, the Griffons going in for a strike. He fired the full clip, knowing he at least took down half of the twelve. Without warning, he flipped around in the saddle, a long-barreled Colt Peacemaker with a brown wood handle. He duel wielded the two pistols as the Grimm came for a second round, firing at the Griffons with deadly accuracy, or at least as close as he could get while riding a horse, but it was still pretty close, especially since he'd been training with Midnight during his time in Jackson, hunting for clues of his town's murderers.

He had decided to stop by his territory before heading back to Vale, to see if it had been invaded by any rival Wildsman and gather some more custom gear, such as the Spring Spear, which now rest inside an adjusted inside trench coat pocket made to fit the three-foot long pole into the coat.

Colt finished off the last of the Griffons and reloaded the Deagle with a clip in the carrier on his thigh, which held clips for his Deagle and Hunter clips for the Punisher. He then took the extra bullets for his Colt from one of his trench coat pockets, and slid them into the cylinder before zapping it back into the Void.

Slowing Midnight to a halt, Colt jumped out of the saddle with heavy breathing heavily as he led the horse to a nearby stream. He checked and reloaded his current stock of ammo, then made a reminder in his Scroll to reload the now-empty clips that rested in the Void before taking his canteen from the sling at his side and taking a few gulps. He sighed in relief after pulling it from his lips, then filled the canteen with the water of the stream.

"Well, that was pretty insane." Church popped into existence from the gauntlet, where he had resided for the past few days, though it'd been a tight fit with the current AI already housed in it, the Intelligence and Logistics Assistant, ILA. "And you seem to have wasted half of what we picked up at the cabin."

"No we didn't, Church." Colt told the AI, "Quit being so dramatic."

"Alright, fine. Now can we stop for the night?" Church sighed.

Colt chuckled. "Alright, we'll stop in the next town."

Midnight sputtered in disagreement, lifting his head to look onward into the desert. Colt followed the gaze of the horse, then saw a battalion of Death Stalkers and a veritable army of Desert Hounds, Beowolves that had adapted to desert conditions, looking more like coyotes, and half to size of a normal Beowolf.

He sighed, then slid the Punisher rifle off his back, then slid a scope out of a pouch, sliding it onto the tactical rail of the rifle, eyepiece flickering into place over his eye and syncing with the scope, both began to adjust to zoom in and adjust to the distance. He began picking them off, sticking to Hunter mode as it was the most accurate, quickly moving the bolt back and forth and hitting multiple Beowolves until he'd had run out of two Hunter clips. He reached back into the drum pouch and drew one of the 250 drums it held, ready for anything. He continued to gauge and hit as many Grimm as many times as possible as the horde closed in, then switched to his shotgun as they came within range, the weapon trailing as a river of metal before hardening in his hands.

He blasted one Hound into pure mist with a blast as it dove, then ducked and shot a second as it came from the side, then kicked another into the sand and fired into its skull.

"Colt, behind you!" Church warned, and the boy looked to see a Deathstalker rear back its tail to strike. Colt rolled back as it came forward with lighting speed, firing another blast into the chest of a Hound as he did so. He rolled right onto his feet and pumped another shell into the chamber, then handled it with one hand and drew his Desert Eagle, firing the shotgun as a Hound dived and the Deagle at two nearing others, taking all three down.

Holstering his pistol, he grunted as a Deathstalker swiped from the side, knocking him back. He pumped the shotgun, fired on an attacking Beowolf, and saw Summit tear into another in his vision.

"Church, how's the gauntlet doing?"

"35% battery, Colt. Aura is at 75%."

"We can make it." Colt said, glaring at the Deathstalker before rolling to avoid its stinger and leaping as soon as he gained his footing onto the creatures back drawing his sword to slice off its tail with a few powerful strikes, then drive the blade into the soft spots of bone plating and uncovered surface, tearing into the skin by dragging it across. The Deathstalker screeched, and tried to shake him off, but his sword gave him a good handhold until it collapsed, mist beginning to rise.

"I really need to downsize my arsenal with mecha-shift weapons." He sighed, then leaped into the remaining hounds brandishing his sword. He sliced and diced into the Grimm as a speeding blur, fire licking along his blades and body, silver and black flames along with the regular brand. He soon encountered a second Deathstalker, and after dodging and blocking, he rolled underneath it, driving his blade into the less protected belly as well as placing adhesive IEDs before rolling out and running, slashing the Desert Hounds in his way.

When the explosion took out the Deathstalker and a few wolves standing next to it, Colt looked to see Summit tearing out the dark throat of a Hound. Between the two of them, only a dozen Hounds remained, others having fled, and the rest evaporating into mist. He grinned, then switched to his shotgun once more, reloading to full six-shell capacity, and dove into the fray. Two blasts killed the front Grimm, and another took down another Hound, the creature falling with a howl. Colt turned and his weapon was knocked out of place, leaving him open for a Hound's bite. He stepped back while reaching to draw his throwing knife, slamming it into the upper jaw of the gaping mouth while adjusting to fire his weapon into the chest of one to his rear, twisting to fire and pulling the blade back at once.

Colt threw the knife into another Hound and then pumped his shotgun and firing at another closing Grimm, twirling to kick a smaller Hound back and seeing Summit dive for the fallen creature. He shifted his gaze and shot the last one standing, the others having been destroyed by Colt and Summit, and he stepped back, reloading his weapons and retrieving his knife, cleaning the blood in the grass, and then returning to his horse, who had retreated to a safe distance. Midnight bumped him in the head as a congratulations and Summit barked.

"Well, that was fun." Church said sarcastically. "Can we please get somewhere safe for the night?"

"Alright, Church. We'll stop in the next town."
