Knuckles the Echidna (Sonic Boom)

"Strong. Determined. The muscle of the team."

- Sonic Boom Official Website

Knuckles the Echidna is one of the main characters in the Sonic Boom series. He is an anthropomorphic echidna and serves as the muscle of Team Sonic.

Concept and Creation
When developing the character designs, Knuckles was made larger and more muscular to emphasize his strength, his role as the strong guy on the team and the bruiser he is.

The sports tape Knuckles wears is inspired by fighters and American football players and is meant to give him a sense of practical heroism by showing that that he is not vain, which is a trait more fitting for villains, when saving the world, and to give him a more grounded approach. It is worn especially around his arms to emphasize that his specialty is power.

Appearance
Knuckles closely resembles his main series counterpart in overall characteristics, but is quite drastically different in terms of physical proportions. He is much larger than all of his team-mates, standing over a head taller than Sonic, and is considerably more muscular. He has an incredibly large torso, broad shoulders and thick muscular arms, making him very top-heavy, and possesses as well longer legs and quills.

For attire, Knuckles wears a pair of red and yellow shoes, designed with wrap-like markings, that have green cuffs and grey metal plates on top. He also has white sports tape wrapped around his hands and knuckle-spikes, the lower half of his arms and legs, and his biceps, making him similar to a Muay Thai boxer.

Sonic Boom: Rise of Lyric
In Sonic Boom: Rise of Lyric, Knuckles was with Sonic, Tails and Amy in another endeavor to foil Dr. Eggman's evil plans when they arrived on an new island. There, they find an ancient tomb sealed deep within the island where Knuckles and the crew come across a powerful villain from the Ancients named Lyric, who plans to power his army of war mongering robots with the Chaos Crystals to destroy everything organic and create a world of twisted metal and robots. To stop Lyric, Knuckles and his friends have to work together and find the Chaos Crystals before Lyric. In this game he has the ability to climb wall and dig underground. But he can only use those abilityes in areas that have purple dirt or purple rocks. He can also destroy enemies faster as a result of being the strongest in the group.

Sonic Boom: Shattered Crystal
In Sonic Boom: Shattered Crystal, Knuckles, Sonic and Tails and Amy rescued Sticks when she was caught in a rockslide. Brushing off Sticks' claims that an underground army would destroy them all, Knuckles followed Amy to an ancient temple she was researching where he stood guard outside. Later, Knuckles teamed up with Sonic, Tails and Sticks to track down and save Amy who had been kidnapped by Lyric and his robot army, who sought to use her archaeological knowledge to find a Lost Crystal of Power and seize its power.

TV series
When Sonic held try-outs for a new sidekick, Knuckles went there to make Sonic his sidekick, but Sonic rejected the offer. Eventually, his sidekick plans did not work out, which Knuckles told Amy when he met her. This inspired Amy to try for being his sidekick, and Knuckles was impressed.

When Knuckles and his friends came to visit Tails' house, they discovered that Sonic and Tails were letting Dr. Eggman, Orbot and Cubot stay here while their lair underwent repairs. Naturally, Knuckles wasn't fond of the idea. After two days, where Eggman had kept Sonic and Tails up all night and exhausted them, Knuckles and his friends learned from Eggman that he lied about his lair for the purpose of exhausting Sonic and Tails in their home, and summoned Obliteratorbot to destroy them. However, the robot misheard Eggman's orders and instead attacked his lair. Accepting to help Eggman stop the robot, Knuckles and his allies got to the lair where Knuckles, Amy and Sticks distracted the robot long enough for the others to reach its kill switches, though they were too late to save the lair.

While Knuckles was on the beach with Sonic, Amy and Sticks, Tails showed them his invention UT, a robot capable of translating any language. However, the robot created tension between Knuckles and the others by translating their private thoughts from the subtext of their speech. The following day, Tails and UT returned where the robot "translated" their comments into insults at themselves. As fights broke out, Tails discovered that UT here was a fake sent by Eggman to tear the team apart. However, Knuckles and the others did not follow Tails on his rescue mission to save the real UT, having deemed UT not worth saving. Later, UT returned to Knuckles and the others where it revealed a message from Tails and translated it into a distress call to rescue Tails from Eggman's lair. Knuckles and the team soon got to Eggman's lair where they freed Tails and beat Eggman's guard robot. While Knuckles had found peace with UT however, Sticks quickly threw it into the sea.

When Eggman had his Anti-fire Bot attacked the local village, Team Sonic came and stopped it. After the mission though, Sticks displayed ill treatment of animals so Knuckles and his team convinced Sticks to get a pet to learn animal compassion. However, to their surprise, Sticks chose a disgusting robo-dog named Buster for a pet. Over the next week, Buster was an annoyance to Knuckles and the rest, which ended in Buster keeping them from stopping a robbery committed Orbot and Cubot. Pushed to their limits, Knuckles and the team tried to make Sticks get rid of Buster when Eggman appeared with a gift for Buster. As Eggman revealed he created Buster, his gift transformed Buster into a larger robot that caught Knuckles and the others. However, they were freed when Sticks managed to assume control over Buster, who then rid of Eggman. The team then said goodbye to Buster when Sticks released him due to his dangerous nature.

As Knuckles and his team came to the village, they discovered meteors were raining down on them. Using her own defense system though, Sticks saved them all. Later, Knuckles and the rest learned from Sticks that she had been nominated for an Awardy Award for her heroism, but refused to go to this elegant event because she would embarrass herself with her feral behavior. Knuckles therefore helped Sticks with her training to become a proper lady. When the team came to the gala, Knuckles made friends with the guests. As the award was handed out however, Knuckles learned Eggman was also a nominee (due to cheating). When Eggman did not get the award, Knuckles tried fighting the doctor's robots with his friends as Eggman retaliated in vengeance, but was caught. However, Knuckles was freed by Sticks and saved from a hit by his new friends while his team beat Eggman and saved the gala.

While the team were making lunch, Knuckles played around with the food against Amy's decorative instructions, making her feel unappreciated. Just then, Eggman showed up to hire Amy to redecorate his lair for Modern Lair Magazine which Amy accepted to Knuckles' shock. Eventually, Knuckles and the team admitted it was not the same without Amy, so they went to Eggman's lair to see her. When arriving there, Eggman claimed Amy wanted to stay with him. Refusing to believe this, Knuckles and the team broke into the lair and freed Amy from a cage, making peace with her. Team Sonic then trashed Eggman's lair and his robots on their way out, which resulted in Eggman not getting a place in Modern Lair Magazine.

When Knuckles passed by Sonic's shack, he found a batch of cookies and ate one. However, it was actually evil cookies made by Eggman which turned Knuckles into a clone of the doctor. Now evil, Knuckles regrouped with Tails, Amy and Sticks (who had also eaten the evil cookies) under Eggman's tutelage, planning Sonic's destruction. When Sonic arrived to save them, Knuckles attacked him with the others, but when they had him cornered, they started fighting over who deserved the honor for capturing Sonic. Amidst the fighting, Knuckles and the others were turned back to normal by Sonic and Eggman (who Sonic turned good with a cookie containing his DNA). The good Eggman thought they would work together from now on, but Team Sonic did not like the idea and restored the doctor to normal too.

Archie Comics
On a bright day on the beach, Knuckles came to help Sonic and Tails fight Dr. Eggman in his Big Boy, but got stomped on. After Amy pulled him up and chided him for his cockiness, Knuckles joined his friends in a coordinated attack laid out by Amy and struck the mech at key point, making it fall and forcing Eggman to retreat.

Shortly after, Sticks arrived on the beach and told them that Tails' house had been robbed. Knuckles and gang followed Sticks to Tails' house, where he discovered that it was gone: what Sticks meant was that Tails' whole house had been stolen, and she described the thief as a "cyborg rock golem", created by Eggman, which left with the house. Though Knuckles had a hard time understanding the situation, Sticks seemingly caught the scent of the robot and they followed her. Though it turned out Sticks was only smelling the grass, the group still found the Rock-cyborg by following its footprints. Knuckles and Amy then began setting up an ambush for the Rock-cyborg and bring Tails' house back on its foundation, but Knuckles wanted to fight and had trouble understanding the plan, which made Amy tell him to "actually think" for once. However, this made Knuckles grow angry in silence. Once Sonic lured the Rock-cyborg to them, Knuckles and Amy attacked its legs while Tails and Sticks hit it from behind, allowing Sonic to destroy it and bring Tails' house back on its foundation.

Tired of being ragged on, Knuckles decided to prove his smarts by faking an alliance with Eggman and then strike. So the next day, Knuckles went to Dr. Eggman's lair where he got to join him. When Eggman later attacked the island in his Big Boy again, Knuckles assisted the doctor in fighting and capturing his friends in cages when they fought back, where he claimed he switched sides because of Amy's criticism. Things got emotional when he faced Amy until she too was caught. In the Big Boy's cargo, Knuckles revealed his plan to his team, but Amy pointed out that he had let Eggman win this way. Knuckles sunk into a depression over his blunder until Tails and Amy restored his confidence by convincing him that his plan was brilliant. Knuckles then faced Eggman, got rid of Orbot and Cubot, and made Eggman retreat by destroying the mech. When his team's escape from the Big Boy, Knuckles accepted Amy's apology to him. After he got rid of Orbot and Cubot again however, Knuckles noticed Amy panicking over losing her piko hammer.

Personality
Knuckles is described as a "punch-first-and-keep-punching-until-you-need-a-punch-break" kind of echidna, and the best solution to a problem for him is to smash it to pieces. He is determined and strong of character, but tends to be rather cocky and get into trouble.

Knuckles is the opposite of Sonic: he is stubborn, likes to take his time and very naive. He is not the brightest of fellows and is a little slow on the uptake, as it takes him a significant time to process even simplified explanations. He is also a bit goofy and easily distracted to the point where he is drawn to things as simple as shiny objects. Despite his rough personality though, Knuckles does have a soft spot: he loves nature and is incredibly loyal to his friends.

Knuckles comes off as a little sensitive about his intelligence. He takes great offense when someone calls him stupid and will go to extreme lengths to prove otherwise. Also, when Knuckles got his team into trouble with his half-baked plan, he sunk into a depression of self-berating over his imposed stupidity (even crying about it) until his friends restored his confidence.

Powers and Abilities
Described as the "muscle of the team", Knuckles possesses incredible strength, enough to smash large rocks with his bare fists, tear apart tri-polymer alloy and even swing the colossal arm of the Big Boy mech around without effort. He also has incredible physical durability, only getting a bump from hitting a falling boulder with his head and was only dazed after being stomped halfway into the ground by the Big Boy.

Using the spikes on his hands, Knuckles is able to dig through the ground and climb onto walls.

Sonic the Hedgehog
Sonic the Hedgehog is one of Knuckles' team-mates and closest companions, despite them being complete opposites. He considers Sonic as his friend, though the two of them are always disagreeing. Between them, Knuckles has a friendly rivalry going on with Sonic and he cannot help competing with him. At times, he also thinks of Sonic as his sidekick.

While Knuckles is irritated by Sonic's snarky comments, they share a mutual bond of respect and actually want to be buddies deep down, but both of them are too stubborn to admit it. During their mission to stop Lyric, Knuckles was quick to blame Sonic for Lyric's release but was proud of his growth during the venture. Also, when it was thought Sonic would fall to his death, Knuckles refused to give up on him. The two are also shown to goof off together.

Amy Rose
Amy Rose is one of Knuckles' friends and team-mates. When Knuckles has trouble understanding something, Amy usually is the one who explains it to him, but with limited success. They are also essentially opposites in how they deal with threats, with Knuckles facing trouble head-on without a plan while Amy thinks strategically ahead. This creates some tension between them and Knuckles does not take kindly to how Amy criticizes him when he notices it.

Sticks the Badger
Sticks the Badger is another of Knuckles' friends and team-mates. While Knuckles behaves friendly and supportive towards Sticks, he honestly thinks she is a whack-job.
