Jules, The Father of Sonic
Shortly before crashing on Mobius, Sonic (back when he was known as Olgilvie) had a legacy to live up to in the form of his father, Jules, a low-class Nikuhog warrior whose power rivaled that of Black Doom, king of the Nikuhogs. While Olgilvie was being prepared to be sent to Mobius, Jules and his crew are on an assignment to exterminate all the life forms of Planet Psychee. After the planet is seemingly devoid of all other life, Jules and crew rest up and celebrate their victory... Until one remaining warrior catches him (and loudly claiming "I CAN SEE THE FUTURE!") off guard and decides to give him the "gift" of seeing the future. This gives him the ability to see the destruction of Planet Niku, and almost the entire Nikuhog race along with it, at the hands of their master, Eggman (the Jim Cummings version). Also, he sees the salvation of the planet Mobius through his son, Olgilvie.
Meanwhile, this prediction becomes reality when Eggman decides to destroy the entire Nikuhog race. Within Eggman's spaceship, Eggman is being briefed by his top two henchmen, Orbot and Cubot, in regards to the occurrences in their routine interplanetary galactic trade and conquering. Recent news reveals that the Nikuhogs' strength constantly grows after each battle. Orbot informs Eggman that a band of low-class Nikuhogs had taken over Psychee in just a few days. Cubot states that the job to take Psychee had been in the pool for months, and that not even Eggman's elite squadrons could take Psychee so easily. Eggman, Orbot, and Cubot contemplate the fate of the Nikuhogs due to the growing power of the species and decide to take action in order to avoid further repercussions, as the Nikuhogs might pose a great threat to them in the future. Orbot advises Eggman to eliminate the growing threat before it poses a greater problem. Cubot and his elite SwatBOTs are ordered to eradicate Jules and his teammates.
Jules dismisses the visions he had, and goes to join his team on Planet Purk, but soon discovers his friends are all dead save for his best friend Blur. Blur informs Jules that Eggman is planning to destroy the Nikuhogs due to their growing power. Jules tells Blur that they'll get him to a healing planet and save him, but before he can finish, Blur dies in his arms. Jules changes his agenda and plans to go to Black Doom and warn him of the situation, but they are cut short when he is ambushed by Cubot and his elites. He battles the ones responsible, and defeats them all, but is easily overwhelmed by a single mouth blast from Cubot. He is left severely injured, but manages to make it back to Planet Niku. Though Jules attempts to convey the danger that they are all in to the other Nikuhogs, since he has now realized that Eggman is going to destroy them all, everyone laughs at his claim and Jules alone begins one final assault against Eggman.
Doing away with many of his minor SwatBOTs and sending the Final Spiral Cannon to Eggman himself, Jules seems about to change the future. However, Eggman counters this with his Supernova Bomb, which kills Jules, many of his own SwatBOTs, and destroys Planet Niku itself, all while uttering a maniacal laugh. As he is dying, Jules sees one more vision of the future: his son Olgilvie facing Eggman. Being assured that Olgilvie would be the one to kill Eggman; Jules gives a small smile as he disintegrates along with the planet. As the planet is on the verge of blowing up, Eggman continues laughing at its destruction, as well as telling Cubot and Orbot to watch the "beautiful fireworks". After his demise, Jules wishes his son, Olgilvie, to take care. At the same moment, Olgilvie, who is still in the space pod, wakes up.
Elsewhere, having just completed an assignment on a far-off world, Shadow is informed by E-123 of their home world's destruction (But it's ok because they're going to Dairy Queen!). His pride keeps him from expressing his shock, and he remains outwardly emotionless. Soon afterward, Olgilvie's space pod touches down on Mobius, where he is found by an elderly man named Sir Charles, and giggles happily in the old man's arms (Until he lets go of him and hits his head into a cliff). Charles then decides to care for the boy as his own nephew, and renames him Sonic.
Just when he thinks he's dead, Jules wakes up in a bed on a planet that looks a lot like Planet Niku. He is being treated by two froglike aliens: Dre, the village doctor, and his son Twopock. Jules remarks that the medicine used to heal him is similar to the fluid in Medical Machines and Dre says that the name of the planet is Planet Nikai, so Jules starts to wonder if he is in the past.
Two soldiers then arrive in a spaceship and declare they are going to conquer Planet Nikai. Jules confronts and kills the big one with a powerful roundhouse kick to the face. The other soldier tries to punch Jules, but the Nikuhog dodges and kills him using an Energy Blast. The mayor and the villagers come to thank their violent savior, but Jules flies away to hang out in a cave.
Twopock arrives at the cave with a basket of food his father told him to take to Jules. At first, Jules tells Twopock to leave, but he eventually eats the young alien's food. Twopock comes back again with food multiple times, and Jules seems to be growing tolerant of him. Meanwhile, a member of Eggman's race, Brutus, says it has been ten days since they have not heard from the soldiers Jules killed, so he decides to investigate Planet Nikai himself.
Brutus arrives on Planet Nikai with eight soldiers, but immediately kills one of them because he was standing in front of him. Then, he has the idea to impersonate the Galactic Police and, wearing white cloaks, he and his soldiers go to meet the indigenous population of Planet Nikai.
They arrive at the place where Dre is healing a young kid with his special medicine, and Brutus remarks that the fluid has the power to heal wounds instantly. He and his soldiers tell the population that they came in pursuit of a pair of evildoers who were targeting Planet Nikai for its abundant resources. The Nikai say that Jules already took care of the pair, and Brutus tells them that they will get a nice reward if they allow him to meet Jules.
Looking at Brutus, Twopock remarks that he has blood on his right arm. Afraid, he goes to the cave where Jules is hanging out. While Twopock is telling Jules that he has a bad feeling about the aliens who are in the village, Brutus and his men start terrorizing the planet. Twopock then begs Jules to help them, and Jules accepts, remembering his friends' decimation on Planet Purk.
Jules saves Dre from the soldiers, and when he sees Brutus, he confuses him for Eggman and angrily attacks him with a punch to the face. Brutus counterattacks by giving Jules some kicks powered by his mecha boots, then he begins to crush him, saying that he is the mightiest being in the universe.
With Jules's energy dropping fast, Brutus prepares to deliver the finishing blow, but Twopock leaps forward in an act of courage to save him. However, Brutus notices this and shoots him with his Death Razor Gun to eliminate the Nikai for good. Seeing this, Jules becomes infuriated. For a short second, Jules's anger causes him to see Brutus as Eggman, remembering his betrayal of the Nikuhog race, and he becomes determined to avenge his crew and his newly found friend.
Jules obtains a tremendous amount of energy, formed into waves flowing through his body, and with his might, he turns into the almighty Super Hedgehog. The two warriors continue fighting, but with Jules's newfound powers, he easily defeats Brutus and his minions.
As a last resort, Brutus throws a Death Bomb at Jules, intending to kill him with the last gasp of his energy in his mech suit, but it is pushed back by Jules's Final Spiral Cannon. With an extra push, Jules also joins his own remaining energy with Brutus', making the final blow and sending Brutus into the depths of space. The villagers cheer on Jules, proud of his fantastic efforts, and Jules smiles and gives them a thumbs up.
Later on, however, Brutus is seen floating through space, barely alive in his mech suit. His spaceship's men quickly take care of him, putting him under respiratory assistance. As he recovers he recalls back this incredible transformation, and informs his crew to warn his descendants about it (presenting how Eggman's family came to know about and fear the legend of the Super Hedgehog).
And so, Jules made his way off of Planet Nikai, bidding goodbye to the friends he made. He had found a new purpose in life.
