Unknown from M.E.

"Unknown from M.E." is the theme song of Knuckles the Echidna from Sonic Adventure and Sonic Adventure 2. It was performed by Marlon Saunders with Dred Foxx in Sonic Adventure, and by Marlon Saunders and Hunnid-P in Sonic Adventure 2. It was also featured in Sonic & the Black Knight as Sir Gawain's theme and could be played when the Medal of Gawain is used.

Legacy
Like most of the character theme songs from the Adventure games, the lyrics of both versions of "Unknown From M.E." are written in a way so that Knuckles himself is talking. He talks about how he never wanted to be given the lonely job of watching the Master Emerald with lines like, "Is this the way, the path I chose?" However, he still fulfills his responsibilities as Guardian like when he says, "My duty is to save the flower from evil deterioration." He also talks about his great strength and stubborn personality with lines like, "No-one stops Knuckles' feat," and "Cold and stubborn but I'm still gon' live it." Knuckles even mentions his rivalry with Sonic in the line, "Don't approve of him, but gotta trust him."

There are differences between the Sonic Adventure version and the Sonic Adventure 2 version. The arrangement is much different, and while the Sonic Adventure version consists more of acoustic and live-recorded instruments, the Sonic Adventure 2 version consists more of electronic sounds and much more programming.

 * Here I come, rougher than the rest of them
 * The best of them, tougher than leather
 * You can call me Knuckles, unlike Sonic I don't chuckle
 * I'd rather flex my muscles

Trivia

 * This song, "Kick the Rock" (the Wild Canyon theme), and "Deeper" (the Death Chamber theme) gave Sonic Adventure 2 its mild lyrics warning.
 * The infamous line, "Unlike Sonic I don't chuckle, I'd rather flex my muscles," from the Sonic Adventure version of the song, has been ridiculed by fans as being "too corny."
 * The lyrics for the Sonic Adventure version of "Unknown from M.E." calls Knuckles a porcupine, but he is actually an Echidna (The two species look similar, but are unrelated). Scylla calls Knuckles a porcupine too.
 * In Sonic and Sega All-Stars Racing, the SA2 version of the song plays when Knuckles uses his All-Star Move.
 * In Sonic & All-Stars Racing Transformed, the version from Sonic Adventure is heard when Knuckles uses his All-Star Move.
 * The M.E. could be a reference to the Master Emerald.
 * In Sonic & The Black Knight, if you equip the Medal of Gawain, you can hear a shortened version of the SA version of the song.
 * In the Sonic Adventure 2 version, this is the first song where a curse word ("damn") is used in the Sonic series. This was also the main reason why the ESRB rating for Sonic Adventure 2: Battle had the "Mild Lyrics" warning, alongside "Deeper" (which ironically censored the conversation the warning would have been at) and "Kick the Rock!" (which had unintended double entendres laced into the lyrics, in reference to the Master Emerald/its shards).
 * The line "Streaking lights, loud sounds, and instinct are the elements that keep me going" is Knuckles' gameplay aspect. The emerald shards, listening closely to the emerald detector and roaming the action stage to find the shards.
 * The song features a singer named Dred Foxx. Dred Foxx was the voice actor for PaRappa in the PaRappa the Rapper video game series.
