Character File: Solid Snake

In his early glory, Solid Snake wasn't quite as appealing as he is in "Guns of the Patriots."

First appearance: "Metal Gear" (MX2 computer/NES, 1987/1988)

Sometimes it's hard working alone. But when you're in charge of completing a set of covert operations it can be cool (or so I'd like to believe). Well, at least Solid Snake makes it look cool.

Long before PlayStation 3 owners were wowed with the cinematic presentation that is "Metal Gear Solid 4: Guns of the Patriots," Snake was just a rookie spy for FOXHOUND in the original "Metal Gear." And since then, he's continuously fought to get his hands on the Metal Gear weapon.

Snake, whose real name is "David" early on, is the creation of Hideo Kojima. His early appearances and spin offs were on computers, home consoles and handhelds before really taking off in the "Metal Gear Solid" series during the PlayStation generation. He's destroyed the Metal Gear, rescued kidnapped prisoners and more over the years. Putting all the "Metal Gear" titles together tells the complete story of Snake's career. Snake helped make the "Metal Gear" series one the founders of the stealth-game genre.

Character File: Doctor Ivo "Eggman" Robotnik

Hey, aren't you one of the Rough Riders?

First appearance: "Sonic the Hedgehog" (Sega Genesis/Master System, 1991)

For almost 20 years now, Dr. Robotnik has seen the fall of many of his machines at the hands (and feet) of one Sonic the Hedgehog. But despite his many feeble attempts to destroy Sega's blue mascot, the guy who turned cute little fuzzy animals into robots never seems to give up.

Robotnik, who was in part based on our 26th President of the United States, Theodore Roosevelt (a more pudgy version, at least), is actually who made Sonic fast (and blue). And the pair were friends until an accident embedded the doc with chaos energy, transforming him into the antagonist we all know of today. Since then he's acquired the "Pinky and the Brain" syndrome, where he tries to take over the world no matter how many times he's unsuccessful in the process. He also apparently has a "Star Wars" fascination, based on the creation of his outer space-floating "Death Egg" in "Sonic 2."

But this robust fellow hasn't spent all of his time being trampled by Sonic and his friends. He was the central character in 1993's "Dr. Robotnik's Mean Bean Machine," a game more in the style of "Tetris" and "Dr. Mario" than a 2D platformer. He's also been a playable character over the years while starring in animated shows and comics.

Character File: Pit

The cover for the Japanese Famicom Disk System version of "Kid Icarus."

First appearance: "Kid Icarus" (Famicom Disk System/NES, 1986/87)

For many of us gamers in the 1980s, "Kid Icarus" played second fiddle to "Metroid," which featured Nintendo's bounty-hunting heroine Samus Aran. But "KI" was actually similar to "Metroid" in gameplay, with the hero being an Icarus/Cupid hybrid named Pit (and I'll bet you thought his name was actually "Kid Icarus"). In his gaming debut, the "little angel" used his magical bow to defeat Medusa in the Underworld. Pit's first adventure can be found in several "best game" lists.

But then he disappeared. Where did he go?

Well those of you (like me) who remember the cartoon "Captain N: The Game Master" remember Pit was a character on the show, and in fact named - you guessed it - Kid Icarus! He also appeared in the Captain N comic book series. Then after a long hiatus as a major playable character, Pit made his triumphant return in 2008's "Super Smash Bros. Brawl" for the Nintendo Wii. The original "Kid Icarus" is also available through the Wii Virtual Console.

Otherwise, he's made cameos in other games such as "Tetris," "Super Smash Bros. Melee," "WarioWare: Twisted!" and "WarioWare: Smooth Moves."
