Metropolis Heroes! - A Sonic Movie and DC Super Hero Girls Crossover

Name: Knuckles the Echidna

Appearance: Knuckles is an anthropomorphic echidna with predominantly red fur that covers most of his body, a black and pointy nose on his peach-furred muzzle, a white crescent-shaped patch of fur on his chest, and amethyst eyes. His eyes in particular glow red whenever he utilizes his Chaos Energy-based powers (Like Sonic). He also has seven dreadlock-like spines around the sides and back of his head, broad shoulders, and a medium-sized, tri-crooked tail.

For attire, Knuckles wears two large white boxing gloves with pointy spiked knuckles attached to them. He also wears red and yellow mountain boots. Each has the top folded down to reveal a soft green interior. The soles are light gray and each possess a metal, hextuple-bolted plate on top. From "Flames of Disaster" to "What Happens in Reno, Stays in Reno" Knuckles wears a brown fedora with a black band and three gold stars in red with gold lining circles at the front of the band, which originally belonged to Jack Sinclair before Wade took it from him and gave it to Knuckles. When he was much younger, Knuckles donned a wooden tribal mask with feathers on it that was shaped in the form of a skull. On his white gloves and white footwear, he wore grayed-out sports tape. Additionally, Knuckles wore green cuffs on his ankles and wrists, as well as a beaded necklace. On parts of his face, dreadlocks, masks, Knuckles wore some white paint.

Personality: Knuckles is described as being serious in nature, yet still naïve at times. Being better suited for combat than Sonic in many ways, his entire existence is about honor and about being a warrior, to the point where he appears to be a force of nature. Proud of his heritage, he tends to be somewhat overconfident and arrogant, looking down upon Sonic for his inexperience as a warrior and claiming that he does not need Sonic's powers because he has his own.

Knuckles is very determined and meticulous when he is pursuing his goals, never letting go of his task or accepting the possibility of giving up. He is also very much a loner by instinct and prefers to do things on his own. However, he is willing to betray his own instincts and ask for help if he recognizes a task that may be beyond his capabilities. Despite this, being as honorable as he is, he is fair and possesses his own strong sense of justice, which compels him to come to the aid of even his enemies if he feels that he owes them a debt. Due to holding honor and loyalty in such high regard, he will express dissatisfaction if he sees a lack of an honorable attitude in other people; despite this, however, he is not above using tactics that would normally be considered dishonorable by others, such as when fighting against Eggman's mech, he suggested attacking the groin, a dirty tactic considered by many to be a cheap shot. He is also very direct and bluntly honest.

Knuckles is quite melodramatic and has a habit of making lengthy speeches; for example, he claimed that Sonic attacked him during his "hour of sorrow" when he threw a couple small piles of sand at him. He is also far from tech-savvy, having no idea about the thought process of machines and would even refer to holograms as magic. By the events of his own series he was shown to have learned enough about Earth technology that he is shown owning and easily using a smartphone as well as AirPods. While this makes Knuckles seem somewhat unintelligent, he is in truth just oblivious due to the absence of such elements in his daily life and his straightforward worldview. He is also rather socially awkward, especially when it comes to Earth customs, such as a handshake or the concept of how baseball works. However, he does enjoy having fun in his own way, as he took great pleasure when he prematurely ended the Wachowski's baseball game despite not fully understanding it. Knuckles also has a habit of referring to people by their species instead of their name, such as calling Sonic "Hedgehog" and Tails "Fox".
