Mighty the Armadillo

Mighty the Armadillo is a Mobian armadillo from the mountains of Angel Island, though he was born planet-side in the Kingdom of Mercia. He has known Sonic the Hedgehog since his childhood, though they didn't meet again for almost ten years. After spending much of his youth wandering, he was brought to the Floating Island by Knuckles the Echidna and Vector the Crocodile. One of the original members of the Chaotix, Mighty has fought by their side in numerous battles. He followed the rest of the Chaotix and moved to Knothole to aid in the war against Dr. Eggman during Sonic's absence in space. Following Angel Island's liberation of the Eggman Empire's control, Mighty travels back and forth between the island and New Mobotropolis to both fight with the Chaotix and assist the Knothole Freedom Fighters.

Early Life
Born in the Kingdom of Mercia to a family of thieves, Mighty and his younger sister were too young to realize the actions of his parents, "oblivious in [their] innocence" as Mammoth Mogul put it. After his parents were subsequently sent to prison for their crimes, Mighty sought a method to free them. Discovered by Mammoth Mogul, the ancient Mobian granted Mighty his tremendous strength. Even with his new powers, Mighty failed to rescue his parents however, and imposed exile on himself. (StH: #185)

While wandering Mobius in exile, Mighty was captured by Dr. Ivo Robotnik along with Fiona Fox, Ray the Squirrel and other Mobians. Upon capture he was fitted with special shackles as a precaution against his unusual strength. Taken to a forced labor camp, the captured Mobians were also used as experiments towards the creation of the first Auto Automatons. When a young Fiona Fox was grabbed by robotic guards to be taken away for such an experiment, Mighty angrily lunged at the guard, causing a brief riot in which he, Ray and Fiona were quickly subdued. Fiona was taken away and Mighty and Ray were locked in isolation. The camp was later infiltrated by a young Sonic the Hedgehog, who helped free Mighty from his shackles, allowing Mighty to destroy the bars of his cell. The two went on to cause an uprising in order to free the camp's prisoners. After freeing Ray, the three somehow wound up in an alternate zone due to a Power Gem connected to equipment they'd hoped to disable. Due to a difference in time flow, they appeared to only be gone momentarily. However, Ray was not with them upon their return, and Mighty, angry at the loss of his friend, began to destroy the lab, forcing Robotnik to flee with Fiona. Having lost both Fiona and Ray, Mighty returned to wandering on his own. (KtE: #26, #27, #28)

Joining the Chaotix
Shortly after his escape from the prison complex, Mighty continued to wander the lands searching for a place to call home and soon encountered Knuckles the Echidna for the first time. Attempting to explain to the Echidna terms like "slave labor", "prison camp" and "lab rat", Mighty eventually found himself confused when Knuckles tried to explain what a crocodile was, as he was hoping to find Vector. After the two realized they both had something in common, each having lost their parents, Knuckles offered Mighty the chance to accompany him and Vector back to the Floating Island, which Mighty accepted. (StH: #120)

Mighty began his new life on the island where he was finally able to live in peace. However his peaceful life was disrupted when Renfield T. Rodent and Dr. Ivo Robotnik set up a base of operations on the island disguised as a carnival. Mighty was enlisted by Knuckles along with Vector, Espio the Chameleon and Charmy Bee to help him force Robotnik off the island. After Robotnik's defeat, Mighty joined the newly formed group, the Chaotix. (KCX)

Life on Angel Island
He later went on to enjoy a somewhat peaceful life with the Chaotix. However, this peace was ussualy disrupted because of battles with Enerjak, the Dark Legion, the Freedom Fighters, the Fearsome Foursome, and Mammoth Mogul. Despite all these powerful enemies Mighty's super strength usually helped both he and his friends through. His home on Angel Island is a furnished cave (complete with weight-training equipment) up a cliff in a region called Rocky Hill. (KtE: #1, #2, #3, KMS: #1, #2, #3, KCX)

Rescuing Ray
After the demise of Ivo Robotnik, Mighty was approached by Nic the Weasel who made him an offer; if he would help her recover a treasure from the now-abandoned prison camp, she'd give him a lead on Ray's location. Using Nic's craft, they flew back to the outskirts of the old facility where they were met by, to Mighty's surprise, Fiona Fox. Mighty had assumed Fiona had died, and despite his claims that he and Sonic had tried to save everyone they could, Fiona was extremely bitter about what she saw as having been abandoned. Despite Fiona's attitude, Nic assured her that in order to reach their goal, a mine Power Gem, Mighty's help was necessary. Mighty reminded her that they also needed to look for Ray, but the weasel replied that she didn't know where he was, only where he might be found. After breaking into the abandoned facility and coming across inactive Auto Automations based on various Freedom Fighters, the trio came to their final obstacle; a sealed door of thick metal. Thinking the Power Gem would be locked behind it, Nic told Mighty to open the door. Tearing it down, they discovered not only the gem, but Ray clinging to it. After the incident in which Ray was thought to have been lost to another zone thanks to the gem powering one of Eggman's machines, he reappeared, trapped between zones and having only experienced a few hours time when almost a decade had passed outside. Despite herself and in a rare moment of compassion, Nic attempted to neutralize the power gem to free Ray; however, it was instead destroyed, annoying her. Mighty, however, was glad to have his lost friend back. (KtE: #26, #27, #28)

After the Xorda
Following Sonic's year-long disappearance, Mighty accompanied the Chaotix during their raid on Angel Island to liberate a Dingo-run concentration camp and rescue Knuckles' father Locke from captivity. Following this, Mighty and the others returned to Knothole where they would remain for some time. Mighty was with the rest of the Chaotix in Knothole, playing video games with Vector, when the Egg Fleet attacked and destroyed the city. Enraged at the sight of Ray being captured by Snively's mech (which appeared to disintegrate the target), Mighty viciously attacked, tearing pieces of the mech apart before he too was captured. Mighty, like the vast majority of Knothole's citizens, was transported to the Egg Grape Chambers in New Megaopolis. However, he along with everyone else was eventually freed and transported to New Mobotropolis. (StH: #138, #139, #140, #141, #175, #176, #177)

Mighty remained in New Mobotropolis with the rest of the Chaotix during the Enerjak crisis, though when Julie-Su wanted to leave the city and see if Knuckles was okay, Mighty readily assisted her and the rest of the Chaotix in attacking the city's airfield. However, when Sonic and Tails were dispatched to Angel Island instead, the Chaotix remained in the city. (StH: #181)

Recent Activities
Shortly after the Enerjak crisis was resolved, Mighty remained in behind to help rebuild Freedom HQ while the other Chaotix members went to Angel Island to comfort Knuckles. During this time, Mighty was mind controlled by Mammoth Mogul who still had a magical hold over him since he gave Mighty his strength as a child. Mogul controlled Mighty like a puppet, along with Tails, and Mina Mongoose, to force Sonic to give him New Mobotropolis' Chaos Emerald. While Mogul initially attempted to have the trio subdue Sonic, he then had each one put themselves in life-threatening situations, as for all his speed, Sonic would not be able to save all three at once. Mighty was "ordered" to walk openly into Eggman's territory without resistance, but after Sonic complied, he was released from Mogul's spell, fought off a few attackers and escaped safely. The spell's lingering effects were later completely erased by Merlin Prower as a precaution, though Mighty still possessed his strength. (StH: #185, #186, #187)

Following this, Mighty and the rest of the Chaotix launched an attack on New Megaopolis and successfully destroyed one of Dr. Eggman's communications relays while fighting off the Dark Legion. Later, after the Suppression Squad incident, Mighty and the Chaotix helped the Freedom Fighters in a direct assault on the Eggman Empire. Mighty and Bunnie Rabbot helped break into the Eggdome by using their super strength to smash through the wall and then assisted in fending off the Dark Egg Legion. However, both he and Espio were pinned down by the Legion's laser fire and ended up being saved by Charmy, Saffron, and Ray. After Mighty and Bunnie finished beating down the barricade the DEL set up, he and the others entered to find Eggman defeated and they all returned to New Mobotropolisto celebrate.(StH: #189,, #190, #198, #199, #200)

Abilities
Mighty's name is no lie - Mighty has incredible strength, bestowed upon him by Mammoth Mogul. He is able to easily rip apart metallic objects and can lift incredible masses with relative ease. Once, upon waking up in a hospital, he thought exercise would improve his condition and began lifting weights -- holding his bed (with a nurse perched atop) up over his head with a single hand. He and Bunnie Rabbot were the only ones able to manage even superficial damage to their chambers when held captive in the Egg Grapes, and during other incidents, Mighty is often held by stronger-than-average means to prevent him from escaping. Mighty's powers can fluctuate depending on his health and emotions; when enraged, he's especially destructive. However, his strength has its limits. During a silly play for the children of Knothole, Mighty needed help from Jules Hedgehog and Espio to hoist Rotor (who somehow was cast as Tails) into the air so that Rotor could "fly". (StH: #148)

Mighty's shell is also capable of deflecting laser blasts. (StH: #199)

Personality
Mighty is not particularity aggressive, though he enjoys physical activity and is willing to fight for a good cause, especially for the safety of the weak or small. He is extremely protective of his allies, often quick to shield them or ensure they're uninjured. He is so protective of Ray that when the squirrel is threatened Mighty falls into a terrible rage, as he sees Ray as somewhat innocent. His protective trait of his allies stems from the lingering guilt of his failure to find his parents and his previous abandonment of Ray. Unlike his friend Vector, Mighty holds no grudges and is able to get along with anyone. He tries to only see the good in others.
