Knuckles the Echidna

Knuckles the Echidna is one of the main characters in the Sonic Boom series. He is an anthropomorphic echidna from Angel Island and the last of his kind.[11] He is also the keeper of the Fregosi Sapphire.[22] Knuckles serves as the muscle of Team Sonic, a group of heroes who defends the peace of Seaside Island and the world at large. Unlike his friends, Knuckles is a nomad without a permanent home and lives in nature.he is also jelaus of the 5 night guard sisters and though out the game(appearing in night null)tried to injure them(not cool)

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 a rather large torso, broad shoulders and thick muscular arms, making him very top-heavy, and possesses longer legs and quills. Also, like his main counterpart, he has a white, crescent moon-shaped mark near the top of his chest.

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 wears gloves with knuckle-spikes on them[29] and has white sports tape wrapped around his hands, the lower half of his arms and legs, and his biceps, making him similar to a Muay Thai boxer. He also occasionally wears his Communicator.

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.[9] He is determined and strong of character,[35] but tends to be rather cocky and get into trouble.

Knuckles has shown on several occasions to have a huge ego:[36] he clearly thinks of himself as his team's leader and most capable member,[16][37] and fancies himself very heroic. Also, as a result of his self-pride, Knuckles feels great about himself all the time.[6] However, his self-admiration makes him exaggerate his own recollection of his accomplishments and endeavors to the point of absurdity, leaving him convinced in his mind that he, for example, has various ridiculous superpowers, such as flying.[38][16][36][39] Proud of his manliness, Knuckles has a very macho-orientated attitude which at times makes him sound somewhat archaic.[40] He is also very blunt when expressing his opinions, which makes him come off as insensitive.[41]

Despite his tough-guy personality, Knuckles is a softy on the inside with some noticeable preferences in particular: he loves nature and is very loyal to his friends.[9][35] He can also be protective and even gentle as displayed by his dedication to the Fregosi Sapphire and Ms. Tomatopotamus.[22][42] He comes also off as being somewhat sociable and out-going. Also, after reevaluating his status as the last of his kind, Knuckles began feeling the kind of loneliness that comes from knowing that you have no relatives, making him both vulnerable and long for the love only a family can provide. However, he has since come to realize that his friends are his family and that their love is just as good.
