Grayson Howl, commonly known as Gear, was a Dire Dog. He is a hybrid between his Dire Wolf mother and German Shepard father. He has grey fur with a patch of brown hair on his head. His right eye is brown and light eye is sky blue. He wears green bandaged gloves and green boots. He mostly spent his time alone, having difficulty with social skills and preferred tinkering with machines, earning the nickname Gear. After an incident one day. Gear started growing machine's out of his body uncontrollably. Not sure what to do, his parents asked Sir Charles Hedgehog, a famous inventor, for help. Together they discovered Gear had mysterious nanites in his body. When they attempted to remove them, the nanites reacted and created a huge robot around Gear's body as some sort of defensive protocol. He was eventually able to turn back into a normal Dire Dog, but white circuits appeared on his forearms, lower legs, upper back, and one on his left cheek. Sir Charles later created a harness to keep the nanites inactive.

Since then, Gear and his parents moved into his family's Old Villa owned by his Uncle. While Gear's Mom would explore ancient ruins from time to time, his Dad and Uncle would train him how to defend himself. Gear also earned the nickname the Villa's Helper for helping the Villa's residence all the time.

Years later, as Gear was with his parents on their way to a newly discovered ruin, Sonic the Hedgehog caused Chaos Control in his skirmish with Eggman, slowly merging the worlds of the planets Mobius and Earth. Gear and his parents were transported to a military base, to which they were taken into custody.

After explaining what had happened, they were shortly shortly released from custody. Gear and his father worked as engineers for the Guardians of United Nations, G.U.N. while his mother traveled the human world. Gear enjoyed life working for G.U.N. until all the Mobians had to return to their home planet to prevent the two worlds from merging and time itself from stopping.

About a year later, an unknown event caused Mobius and Earth to fuse into one large planet without time stopping like scientists predicted. To this day, scientists still try to discover the cause on how the two worlds merged without chaos control.

Gear's parents set off to find ruins of the lost civilization of the Dire Wolves his mother was obsessed with. Gear's mother and uncle were some of the extremely few dire wolves left in the world. However, his parents both went missing when they left. People tried searching for them, but found no trace of them.

One day, Eggman's robots launched an attacked on multiple towns to draw Sonic's attention away from one of his evil plans, including Gear's home villa. Seeing Badniks attacking the people he grew up with, the Dire Dog removed his inhibitor harness. Unlike before, Gear was able to focus and control the nanites to create two giant mechanical gauntlets on his arms.

After fighting off Eggman's robots and helping repair most of the Villa's damage, Gear set out to join G.U.N. for training and to learn more about his nanites. With the help of the human scientist Christopher Thorndyke, Gear discovered new mechanical builds.

The Smack Hands are massive green gauntlets that are generated on Gear's arms. The Smack Hands give him incredible strength, allowing him to break through obstacles or lift heavy objects. When forming them, he has control over the overall size, flexibility, and lengths. Gear can use them to significantly push himself into the air and use them to absorb the impact of the landing. The Smack Hands are capable of acting like a shield. Gear can use the Smack Hands to create huge shockwaves by clapping both of them. Gear can spin the Smack Hands into Combat drills, granting additional power behind his attacks.

The Boogie Pack is a jet pack with a pair of green orange turbine wings. Gear is capable of using it to fly at high speeds. Gear can us the Boogie Pack to travel about 100 mph in a few moments. He can also launch twin turbines at enemies like a bola. They are also capable of firing two large grappling hooks on the top of both turbines. Gear can also use the turbine wings to create compressed air. Unfortunately, there is only so much weight the Boogie Pack can transport at once.

The Slam Cannon is a large orange projectile cannon that Gear can form with either arm. It is positioned to rest on his shoulder. A maw on the back end of the Slam Cannon can extend into the ground and reload solid material. It converts the material into balled ammo that fires with great force.

The Gear Ride is a green hover motorbike that Gear can form out of his lower legs. The vehicle can drive over any terrain and can go over 200 mph. It has a retractible battering ram instead of an engine block and can be used like a shield to break through thick obstacles. A dark brown helmet is formed over Gear's head for protection.

The Punk Busters are a pair of large green super boots with retractible spikes on the soles and also jet boosters on the heels to amplify Gear's speed and kicking power. The Punk Busters allow Gear to jump hundreds of feet into the air jump across large distances. Gear can also use the Punk Busters to repel powerful enemies. The Punk Busters can extend its foot to kick enemies away like hydraulic cylinders.

The Big Fat Sword, or B.F.S. for short, is a massive green sword that Gear can form with either arm. Out of all of his builds, it is by far his most lethal build. While it can easily cleave through objects, it can be used to deflect attacks. Using the lever on the side of the big fat sword, the top half of the blade splits apart and rotate at a high velocity. This turns the Big Fat Sword into the Battle Saw, a giant green circular saw that can slice through tough objects.

A couple months later, after Eggman's attack on City Heights and Sonic's defeat, Gear traveled back to his homeland with a handful G.U.N. soldiers on their airship. Gear and G.U.N. work with the Mobian Resistance in the fight against Eggman's growing empire. Today, Gear serves as an vital soldier, stopping many of Eggman's assaults.
