Ed Boon and the team from NetherRealm are in Cologne, Germany to show-off Mortal Kombat X at what is shaping up to be a memorable trade fair! IGN have spoken to Boon about the 2015 fighter in one of the first interviews to come out of 2014's Gamescom and they've uncovered a couple of interesting details!

While no details have come from Gamescom just yet - we've again been teased with the introduction of a new "-Ality" that will be revealed sometime in the near future. That's just the tip of an iceberg that gave us new story and character beats, as well as a bombshell about expected crossovers. Read on:

A Polygon Evo interview with NetherRealm Studios' Ed Boon is again drawing attention toward the likelihood of guest character(s) in 2015's Mortal Kombat X.

The profitable return of crossover fighters hasn't been much of a secret. As well as various references on Twitter -- Boon made guest character considerations known to various outlets during last month's E3 launch [Related Article: E3 2014: Gamespot Full Match Videos & Demo Stream].

Answering questions about a possible return crossover between NetherRealm's two established fighting franchises - Boon leaned toward the negative, "I'd be hard-pressed to have a DC character as a downloadable character in Mortal Kombat X."

This, of course, goes against the grain of Scorpion making the leap to Injustice: Gods Among Us, but there's an explanation for that rooted in the differences between the two franchises. "The main reason is, I have no desire to cut Batman's head off. I have no desire to kill Superman."

As we gear up for next week's E3: the leading topic of speculation remains the next playable roster! Mortal Kombat X will be at the annual gaming mecca to reveal at least 2 more playable characters -- "brand new", or so we're told. We expect to see plenty of familiar faces to go along with them, but not everyone character can make the cut.

Project Lead Ed Boon has spent the last few days setting expectations for E3. Amongst his various clues, allusions & titbits -- the kibosh for some of the more obscure characters fans have requested. With speculation running wild, it's time to spin the wheel of broken dreams and reflect upon Ed's Kharacter Deadpool!

It's a testament to the staying power of the 90s juggernaut that -- despite having very little to do with the DC Comics Universe -- Spawn remains a popular fan choice for Injustice: Gods Among Us.

Never one to shy away from a fight with corporate powerhouses; Spawn creator Todd McFarlane quipped, "Get him in there!", when asked about the game at the recent Toy Fair.

On the hypothetical unlockable appearance, McFarlane joked with GamerFitNation: "And then he takes down everybody! ... Becomes the baddest ass in the whole bunch there."

There's certainly precedent for Spawn taking on the world of fighting games. In 2003, he was the Xbox exclusive character in Namco's Soulcalibur II. The comic book icon has also been the subject of his own exploits, fighting in games like: Spawn: The Eternal and Spawn: In The Demon's Hand.

Despite being one of comics' most famous independent creations, there have been two meetings between Spawn and the DC Universe. In 1994; Spawn/Batman [pictured top] brought the infernal anti-hero into conflict with The Dark Knight under the all-star creative team of Frank Miller and Todd McFarlane. If nothing else, the infamous crossover provided a knock-down, drag-out example of what might happen in a DLC Injustice meet-up. A second one-shot: Batman/Spawn: War Devil was also published by DC Comics.

Once regarded an improbable oddity; the fighting game guest character has become an industry standard. The invasion of outside forces remains a controversial topic for hardcore fans of any series: Mortal Kombat has become a seasoned veteran of the crossover concept, accepting fights at home and abroad.

Kombatants were first establishing their crossover credentials as far back as the nineties. Characters like Sub-Zero and Raiden have lodged appearances in various series, including: NBA Jam, Unreal Tournament and The Grid. Scorpion made the latest Kombat crossover earlier this year, appearing as a Jim Lee designed downloadable guest in NetherRealm Studios' superhero fighter: Injustice: Gods Among Us. The ninja from Hell is expected to be among the pack-in content in November's Ultimate Edition.

In 2011, Mortal Kombat took a turn playing host to two well known guest fighters: Freddy Krueger (DLC) and Kratos (PS3 exclusive).

A whirlwind of speculation combusts into hellfire as DC Entertainment Co-Publisher Jim Lee and NetherRealm Studios Creative Director Ed Boon combine to present the latest downloadable addition to Injustice: Gods Among Us! Mortal Kombat's Scorpion has made the leap and is kicking butt in a new feature trailer!

Update (June 4): Scorpion is now available to DLC Season Pass holders. Everyone else can purchase starting June 11. [via @noobde]

As previously announced, Kratos from God of War will make his first appearance in promotional Mortal Kombat media in the January 2011 issue of Playstation magazine (issue 041) along with the recently confirmed Ermac. Kratos graces the front of this issue along with Scorpion, a continuation of their confrontation in the recent trailer.

After months of rumors and this last week's revelations, Kratos from God of War fame has finally been officially confirmed to appear in the first quarter 2011 game! As previously announced, a new playable character would be revealed on Spike TV's annual VGA show.

There have been long persistent rumors of the Sony exclusive Kratos from God of War fame making an appearance in next year's Mortal Kombat game, but most wrote these off as wishes of fans who wanted to mix two brutal worlds together. Kratos has already stepped inside the world of fighting games once, appearing in Soulcalibur: Broken Destiny last year but never before has he seen action on a medium equal to his own in violence and carnage.

Who could ever forget the great debate on video game violence? Actually, it's still going on thanks to games like the Grand Theft Auto series, but the originator of the term was Midway's Mortal Kombat. The outrage amongst parents began and every company wanted a piece of the marketers dream, controversy. A one-on-one fighter hurled onto the arcade scene shortly after the release of MK in 1992, causing all of those video game hating parents to gasp at the depictions of decapitated limbs, heads, and blood spewing combos. This was the god-awful excuse for Time Killers. 8 characters were available to players from the start, a decent number for it's day. Almost all of them are useless with the exception of the chainsaw wielding maniac Rancid.
