Jackhammer the Echidna is a dark green, anthropomorphic echidna from a different universe. He is 23 and he is currently both a rapper and a breakdancer from Team Underground Elite Breakdancer and Rapper. In his echidna form, he weights just like Knuckles. In his human form, he is 6' 4 and is 230 lbs.
On Earth, he is one of the best breakdancers and rappers inside an underground parking lot, who, along with his brother Sledgehammer, is renowned the best breakdancer and rapper in the universe. The next day, however, just when he and his brother are about to arrive in an underground parking lot for a competition, both he and Sledgehammer dissapears without a trace and he becomes separated from his brother, Sledgehammer. He wakes up, and realizes that he is on another universe, just outside of Mystic Ruins. Another thing he realized that his brother was missing. However, despite being worried about his brother, he starts his journey on his search for his brother.
He stumbles upon Red Mountain (a stage from Sonic Adventure) and that he feels the ground shaking violently. He spots a volcano that is becoming unstable and is about to erupt. Before he can escape, he senses a rare item underneath the ground, and reveals a bright ring. He grabs it, which causes him to glide a lot faster than before. After a bad mishap after visiting Red Mountain, he then starts an adventure on a search for his brother.
Jackhammer is a serious, but otherwise a kind, heroic, and cool echidna and he likes adventures, with his brother, Sledgehammer, by his side. He is also an undisputed breakdancer and rapper, especially for Sledgehammer. He plays a role of a hero, since his powers can prove deadly against his foes nearby. Jackhammer loves ramen, along with his brother, and other certain foods he can eat, and the same goes for Sledgehammer. Unlike Knuckles, he guards his career of being a rapper and a breakdancer, since his techniques has earned him his reputation, alongside with Sledgehammer. He can make his boombox dissapear and reapper within his arsenal. He even enjoys listening to Knuckles' music track.
Like Knuckles, he can glide, but not lose altitude. He can even gain altitudes when he needs to reach higher places, such as foes. While Knuckles can use Shovel Claw to dig through dirt and aquatic enemies, Jackhammer can use his Shadow Claw that can dig through anything (though special care should be taken by not digging through anything too deep), including enemies. Jackhammer can use his breakdancing techniques as combat to battle against unarmed foes, and that he can also release his special ability known as Fists of Fury, where his hands burns on fire and that he can burn down foes in his way by punching them (whilst his fists are on fire), even when outnumbered. His second special ability is known as the Hammerhead Slam, where his aura becomes white and that he can plow through walls, buildings and foes head on with his head, most likely since his head has been hardened enough so that he can break through walls and foes without inflicting any harm to his head. His third and last ability is known as Bling Brigade (accompanied by Sledgehammer); using both chain necklaces, he and Sledgehammer takes them off and uses them as a lasso and by swinging at metal-like foes, this slices foes in half at the same time, with their chain necklaces still intact. He uses his hat as a boomerang which allows it to disarm armed enemies by force, and after it takes down opposing foes, his hat is right back in its place. Here are his well known moves:
- Breakdance Combat
- Shadow Claw
- Boombox EMP (immobilizes enemies)
- Fists of Fury (only when he gains confidence)
- Hammerhead Slam
- Bling Brigade (accompanied by Sledgehammer)
- Can swim on or underwater
If Jackhammer gains altitude too often, the air will soon lack oxygen and Jackhammer would fatally suffocate, and that he must glide down to get some air. By suffocating due to lack of oxygen, his powes and strength is halved, thus not being able to defeat enemies if not able to breathe through oxygen.
