Al Gore, Spider-Man, Justin Bieber, Mikhail Gorbachev and more have all appeared in video games…

These are the kinds of cameos were interested in.

Were also not counting inclusions like special skins that simply change the look of a player character.

With that in mind, lets begin.

Batman enters the fray, although his powers arent quite as accurate, being able to fly and all.

Before this, the character turns green with each hit, just like The Hulk.

Later, Joe even goes up against Godzilla, sans fins, but still obviously the mega monster star.

Thats a lot of special guests for one ninja to handle.

Spider-Man was also put into a pink costume after the rights expired.

Its never explained quite why Spider-Man or Batman felt the need to fight another good guy hero.

Where do I even begin with this one?

As most readers have probably never even heard of it, I should probably explain whatQuik & Silvais.

So, who made the list?

Well, the better question would probably be, who didnt?

This was presumably done to avoid any legal issues with the Factor 5 name, which seemed to work.

Its two-on-two action makes for fast, frantic games, with spectacular dunks and flaming basketballs.

Its also notable as former US President, Bill Clinton graced the wooden floors.

Yes, they had to, didnt they?

It features none other than Justin Beiber as a playable character.

Gorbachev is seen in the game during the ending sequence for Zangief.

Hes dropped off by helicopter, and proceeds to congratulate Zangief for demonstrating Russian superiority.

The pair then indulge in a cossack dance, just to further compound that stereotypical panache.

Its also here where we got to kill one of gamings most popular enemy forces, the Nazis.

Set during World War II, players took on an army of the Third Reich within the titular castle.

This isnt really an odd cameo, you may think, and its not really.

Whats odd is that Hitler wasnt simply in the game, but was sat inside a robotic power suit.

Hmmm, okay then.

Once this suit was destroyed, a rather buff-looking fuhrer dual wielded two massive miniguns.

I had no idea the Nazi leader could lift.

One of these was in CapcomsBionicCommando.

Hes killed by Spencer at the end of the game.

For the American release, the game was censored.

And yes, his head still explodes.

This isnt an actual cameo per se, but it certainly warrants a mention.

This says Gamers rule and Saddam was here.

Capcoms successful RPG series,Breath of Fireis set in a fantasy world full of magic and monsters.

Its certainly not set in the real world, or the world of tournament fighting for that matter.

Well, I guess everyone needs a quiet place to train.

One of the most notable has to be theDoomcameo.

In E1L3 (Death Row), you find a chapel with a cross.

Hitting a switch turns the cross upside down, revealing a cave behind.

Here youll find a deadDoommarine.

Upon discovering this Duke exclaims Thats one doomed space marine!

Hey, it could happen.

Also after a bit of exploring, you could find four dead turtles, complete with masks.

Could this be aTMNTreference?

Well, yes, of course it is.

If there was any doubt, Lo Wang confirms it as he exclaims cowabunga!

This is clearly Duke Nukem, at least it looks like him.

An obvious reference to Dukes penchant for strippers, stealing his catchphrase.

However, sometimes there are odd instances you dont expect.

One in particular is found inSuper Mario RPG.

Well, there are actually two, with one being Link, whos found in the Rosa Inn.

Catching forty winks in the Mushroom Kingdoms castle is Samus Aran ofMetroid.Apparently, shes resting up for Mother Brain.

She could at least give the plumber a hand.

The fighters in theTekkenseries are a skilled bunch.

Some have even had their own spin-off games where they moonlight as super spies.

For the most part, however, they stick to what they know.

That is, apart from the killer OAP with the crazy hair, Heihachi Mishima.

At least, thats ifSmash Court Tennis Pro Tournament 2is anything to go by.

Heihachi Mishima pops up in this game, along with other Namco stars.

If he get angry, and screams You cannot be serious!

Yeah, the mission was even called Two-Faced Tanner, just in case anyone thought it was mere coincidence.

Hes more or less useless out of his car, so weve tagged it with a tracer.

This isnt a cameo by a character, but more of a guest appearance by an actual setting.

Its also possible to see the smoke monster from the series roaming the island.

Fortunately, the rest of the game makes much more sense than the climax of the TV series.

Yes, it still hurts.

Valkyria Chroniclesis a superb, often overlooked gem of a strategic game on PS3.

Its cartoon visuals belie a deep and challenging title, one that rewards genuine tactical play and clever planning.

It also features cameos from another classic,Skies of Arcadia.

More of an Easter egg than a cameo, but one thats too cool to ignore.

InThe Witcher 2s opening tutorial level youll happen upon a rather unlucky individual whos fallen to his death.

During one of the games extra missions you have to rescue a VIP.

This is another possible foreshadowing , but thats another story… Jackson lent his likeness to the game, and performed the voice acting for the role.

He returned in the second game in a larger role.

This wasnt a simple skin replacement either.

Michael Jackson was a different story, however.

We all knew he had some smooth moves, but not within the squared circle.

Thats what you call a proactive war on terror.

Its also got a whole lot ofDiffrent Strokesstar, Gary Coleman in it.

He even did the voice acting.

Alongside characters from the movie, including Meat Loaf and his moobs, Durst was a selectable scrapper.

Hes not selectable from the start, though.
