Seaside Island


 * For other uses, see Bygone Island (disambiguation).

Bygone Island is the main setting of the Sonic Boom franchise. It is a tropical island that houses a number of villages and is where Sonic and his friends live. The island features various regions with climates and environments different from one another, such as a region of ice and snow neighboring a tropical forest.

While Bygone Island is usually peaceful, it is frequently attacked by Dr. Eggman from his lair as the starting point for the doctor's agenda to attain global conquest.

Sonic Boom: Rise of Lyric
A millennium ago, Bygone Island was seemingly an outpost for the Ancients, given the countless local ruins of the Ancients' civilization.

In the present day, the local Village had been heavily damaged, so reconstruction projects were set up. Meanwhile, the island came under the approaching threat of the villainous Lyric the Last Ancient and his forces. However, the majority of the villagers were more concerned with the re-election of Mayor Fink. Eventually, Team Sonic came to Bygone Island to secure the Chaos Crystals. Eluding both Lyric and his temporary ally Dr. Eggman while on the island, Team Sonic used Bygone Island's Crystal Locks to reach the Chaos Crystals before defeating Lyric for good off-island. A party was subsequently held in the Village to celebrate Team Sonic's victory, where Lyric's remaining Destruction Troops were scrapped.

Sonic Boom: Shattered Crystal
Learning that Amy had been kidnapped by Lyric the Last Ancient, Sonic ventured through Seaside Coast to assemble Tails and Sticks for a rescue mission. After reigning in Sticks, Tails devised a way to track Amy, making the group head for the Scrapyard.

Past
For some time, Team Sonic has defended Bygone Island, having saved its main settlement from Dr. Eggman hundred of thousands of times. At one point, the Cubot prototypes immigrated to Bygone Island to hide from Eggman's plans to scrap them.

Season one
When Tails got hurt during a battle with Eggman on the island, Sonic fired him as his sidekick to keep him safe. During Sonic's subsequent sidekick try-outs however, Tails reclaimed his job after he helped Sonic foil Eggman's plot to destroy them by infiltrating the try-outs. For an evil plan, Eggman and his lackeys went to Bygone Island where they weakened Team Sonic for Obliterator Bot by living with them. However, when Obliterator Bot targeted Eggman's lair instead, Eggman got Team Sonic to help stop it. When Tails made UT, Eggman would steal this robot and use it to drive Team Sonic apart. However, Tails discovered Eggman's plot and left the island to rescue UT, prompting Team Sonic to later go save Tails from Eggman. After stopping Anti-fire Bot's assault on the Village, Sticks got herself a pet named Buster which would annoy her team to no end. When Buster turned out to be an Eggman robot made to destroy Team Sonic though, Sticks stopped Buster without hurting him, before setting him free on the island.

After a meteor shower hit Bygone Island, but did little damage, the Awardy Awards were held in the Village. There, Team Sonic stopped Eggman from taking the Awardy Award by force. Another time, Eggman got Amy to help redecorate his lair when she felt unappreciated by her team. Feeling guilty for not treating Amy well, Team Sonic left soon after to get her back to the island. Later at Meh Burger, Eggman hired Dave the Intern as his intern. However, Sonic and Tails would soon leave the island to save the world from Doomsday Devices set off by Eggman and Dave.

Eggman eventually sent some Evil Cookies to Bygone Island which everyone on Team Sonic, except Sonic, ate, turning them into clones of Eggman. Sonic thus had to trek the island to make a cure for his team when he left to save them. During a race across the island, Sonic and Tails met the Gogobas who kept sticking to them so they could protect them. In the end, Sonic and Tails made them stick to Eggman during one of Eggman's attacks. Orbot and Cubot would later come to Bygone Island in search of Eggman, where they incorrectly determined his fate after asking the locals. Then, when Cowbot attacked Team Sonic on Bygone Island, Sonic and Tails were forced to go save Eggman when they made Cowbot target the doctor.

Following a fight with Octopus Bot, most of Team Sonic would help T.W. Barker out with a show on the island while Tails left to work on his Unbolterizer. When Barker kept the heroes as his performers against their will however, Tails rescued them. Bygone Island was later invaded by Eggman's forces when the luck balance of the universe had shifted in Eggman's favor, making him untouchable. However, using Knuckles' currently bad luck which they had been dealing with all day, Team Sonic stopped Eggman and saved the island. A meteor later landed on the island which would switch Sonic and Eggman's minds, leading to several escapades as Sonic worked to get his body back from Eggman.

Bygone Island endured further small evil plots from Eggman before entering a time of peace as Eggman lost his motivation. Sonic's restlessness over the island's peace annoyed his team however, prompting them to re-motivate Eggman. By accident, Tails later destroyed the island's beige berry orchard. As he replanted the trees while his team went to the local pie festival, Tails ignorantly joined the Lightning Bolt Society after Dave had unknowingly seeded some mutant plants. Most of Team Sonic thus had to get Tails back from the Lightning Bolts' initiation ceremony while eluding Eggman to stop the mutant plants. Soon after, Eggman sued Sonic when he faked being injured by him during one of their fights. The following island-renowned trial was held in the Village, and Sonic stood to loose until Amy exposed Eggman's fraud.

As Eggman began selling tomato sauce, every local resident would buy some of it. However, it soon turned out to be an evil scheme when the sauce cans began turning appliances into an army for Eggman to take over the island with. The plan was foiled by Team Sonic. For another scheme, Eggman staged a set-up across the island that made it seem like Sonic was making a horrible noise, thus tricking the hedgehog to wear his Power-absorbant Insoles which would power his Giant Robot with Sonic's running. When Giant Robot faced Team Sonic on the island though, Sonic beat it by overloading it with power. Bygone Island and the rest of the universe later got caught in an timeloop created by one of Eggman's attacks on Team Sonic, making everyone on the island relieve the same day until Eggman and Team Sonic joined forces and broke the loop.

When Sonic and Knuckles awoke Granifier Giganticus―nicknamed "Rocky"―the giant would lounge across the island as Team Sonic tried to make it fall asleep again, while protecting it from Eggman. After dealing with Rocky's kidnapping of Sticks, Team Sonic lured it off the island. Amidst another battle deep within the island, Sonic and Eggman got trapped in Buddy Buddy Temple. However, the pair managed to escape together and bring their allies to safety after they fell into the temple as it began collapsing. As Orbot and Cubot sought a new home on Bygone Island, they learned Eggman's new friend Nominatus plotted to seize Eggman's tech to destroy all lifeforms. Escaping from their own forces to Bygone Island, Eggman and his lackeys made a temporary true with Team Sonic and stopped Nominatus together. When Sonic then had to return a library book, he would get side-tracked all over the island by Eggman and many others before he returned the book.

In a battle of the sexes, Sonic and Knuckles had a race against Team Sticks through the wilderness of the island to Hidden Meadows, which the latter pair won with ease. When Eggman then got lured into a tech-based prank on the island by Team Sonic, he decided to forsake tech for the time being. Not long after, the island got bombarded by random attacks from Eggman's lair, caused by the Lightning Bolt Society who had occupied the lair. In the end, Team Sonic and Eggman united to stop the group. Soon after, the Battle of the Buns erupted in the Village, where Chez Amy and Meh Burger competed against each other to attract customers. While Chez Amy ultimately won with the aid of Eggman, the restaurant would be destroyed shortly after by a disgruntled Eggman. Swifty the Shrew later appeared and the villagers were captivated by this new hero, except for Sonic, and gradually the rest of his team. When Swifty then got Sonic banished from the Village by "beating" him in a race, Eggman revealed Swifty was his robot agent. As Eggman's forces trashed the Village for a theme park, the Village Council brought Sonic back, who then handled Eggman. Believing later that her team had been cursed, Sticks took Team Sonic to a mystical mamoset on the island to break the curse, whom they saved from Eggman as well. When the island's annual Chili Dog Cook-Off arrived, Team Sonic discovered that phony peppers were in circulation, prompting Knuckles to go find a new pepper, only to disappear. His friends found him a day after the cook-off, passed out from eating a potent pepper.

Foiling Eggman's Explode-o-nut, Team Sonic helped with Sticks' forced yardsale when the entrance to the evil Froglodites' caves beneath the island was unearthed. Saving Sticks from the Froglodites after they kidnapped her, Team Sonic resealed the Froglodites. The Village was later thrown into chaos when Knuckles was made deputy mayor, so Team Sonic and Eggman joined forces to stop him. However, when Eggman turned against the heroes, Team Sonic kept him from seizing power over the Village. Eventually, Eggman went to Bygone Island to shoot a mind-enslavement movie and tricked Team Sonic's members into helping him, although the plan would still fail. A uproar in the Village subsequently arose when the villagers believed Sonic was being insensitive towards Mike the Ox. Eventually, the villagers' attitude made Sonic retire despite his attempts to make it right. With the other heroes gone on a trip, the Lightning Bolt Society took this opportunity to harass the villagers until Sonic returned, who handled both the Lightning Bolts and an Eggman attack at the same time, and earned back the villagers' respect.

When an alternate Knuckles appeared on Bygone Island, Team Sonic helped him get home before his presence could destroy their reality. Orbot and Cubot were later sent to Bygone Island to capture the troublesome Cubot prototypes. Instead, the duo got Sonic and Tails to help the prototypes, whom Cubot joined. Eggman thus went to destroy the prototypes himself, but Sonic and Tails stopped him while Cubot returned to Eggman's service. As Dave tried in vain to destroy Team Sonic himself and prove himself a villain, he inadvertently caught Eggman and hijacked his robots. However, his next attack on the Village went poorly and he was defeated by Sonic after he freed Eggman. On New Year's Eve, after his failure with his Ball Bots, Eggman launched his Slow Motion Machine at the Village Center's party to slow down time long enough for him to beat Sonic once before the New Year. In the end, Sonic let Eggman win and the doctor restored time, though no one saw his victory.

As the Justin Beaver feber hit the island, the female villagers became Justin fan girls and consumer zombies due to Justin's mind control music. When Justin's producer Dixon sat up a concert to spread the mind control though, Dreamboat Express/Dude-itude stopped him. After stopping Eggman's Decimator Bot attack, Team Sonic would help Tails face his crush Zooey. While their advises failed, Tails won Zooey over in his own way while stopping an Eggman attack on the Village. Another time, Sonic and Knuckles joined Bro-Down Showdown to win a new couch for Amy. However, Sonic got paired up with Eggman for the show instead, which was planned by Eggman so he could set Obliterator Bot loose on the Village while Sonic was occupied. However, Sonic gave up the couch to help Knuckles stop the robot.

Amongst Comedy Chimp's publicity shots, Knuckles became the island's new celebrity with his trash can trend, eventually replacing Comedy Chimp on the Comedy Chimp Show. As such, Comedy Chimp elicited Eggman to steal back his show. With his friends protecting him from Eggman, Knuckles rejoined his team, while Comedy Chimp reclaimed his job. Sonic, Knuckles and Amy later found Perci after an accident and took her to Tails' Workshop to help her when the building caught on fire. Tails thus spent some time sorting out what had happened. Eventually, a crime wave hit the Village. With Sonic as the prime suspect and poised to be arrested, Sonic went underground. Discovering it was one of Eggman's plots, Sonic and his allies cleared Sonic's name by bringing in the true thief: Metal Sonic.

With the arrival of the Robot Battle Royale, the island's inventors met up for a battle tournament. There, Eggman stole Tails' Hypno-bot which he used to recruit Tails' inventions for a new army. However, he was stopped by Team Sonic. While Bygone Island was hit by a heatwave, the Archipelago Homeowners Association learned Eggman was illegally housing robots and threatened him with eviction. Meanwhile, Team Sonic noticed Eggman's latest Badniks were acting strange and left the island to investigate, promptly saving the homeowners association from Eggman. As Fuzzy Puppies came to the island, many villagers would take up the game, including Amy and Eggman, who bonded over the game. At Puppy Con however, Eggman tried stealing a rare game piece, until Amy put him in his place.

After Team Sonic foiled his plans to demoralize the Village, Eggman made them fight him not as a group but one at a time, allowing him to beat each hero. Finally though, Team Sonic beat Eggman by switching out as needed instead of sticking to a schedule. Upon saving the Village for the millionth time, Team Sonic got the Greatest Role Model of All Time Award. Because the team still horsed around though, Mayor Fink gave them an image specialist to make them better role models, who soon kept them from using force against Eggman. However, Sticks got her team back to their old ways. On a particular poor day, Team Sonic upset Amy badly due to her play A Rose Without Thorns. As such, they put up her play in the Village as an apology.

Knuckles later tried to make amends to Charlie for past mistakes, only to ruin Charlie's life and drive him towards villainy. While initially reluctant, Knuckles eventually beat Charlie, who had managed to get back on his feet. As Team Sonic tried building a bookcase in the Village, they were attacked by Team Eggman. Even with Shadow the Hedgehog coming to the villains' aid though, Team Sonic won the fight.

Archie Comics
After driving Dr. Eggman's Big Boy off Bygone Island, Team Sonic helped Tails reclaim his house from the Rock-cyborg. The doctor soon returned with the Big Boy, but Team Sonic managed to drive it away again despite complications brought on by Knuckles' attempts to prove his smarts. However, Amy lost her piko hammer in the process, so most of Team Sonic searched the island for it while Sticks kept Amy calm. They eventually found the hammer, after it was launched back to Bygone Island from Eggman's lair. Team Sonic was attacked by an upgraded Big Boy again not long after, but thanks to Sticks and the Rock of Justice, the heroes pulled off a narrow victory.

Feeling destructive, Eggman made several trips to Bygone Island to sell a bridge to destroy and later try to earn the villagers' trusts for future plots, only for the majority of his attempts to end badly. Soon after, Eggman set up the Go-kart Pan-island Grand Prix and got Team Sonic to compete with him in a race around Bygone Island. Despite Eggman cheating, Sonic won the race, although Eggman got the data he needed for Project Hodge Podge. When the Maverick Hunters then arrived on Bygone Island, Sticks and her team joined them on a cross-dimensional adventure, which she would tell to her skeptical team afterwards.

When Sonic let Kyle the Gorilla crash with him after getting him out of Eggman's lair, the hedgehog spent some time helping Kyle get a job on Bygone Island. Eggman himself would soon after spy on Team Sonic with cameras around the island to find his lost earpiece.
