Emperor Demon Dragon God Java (天王鬼龍神 ジャバ Tennō Ki Ryūjin Jaba?), formerly known in western releases as "Red Falcon", is the first main antagonist in the Contra series. He was introduced in 1987 as the final boss of the arcade version of Contra. He belongs to the Red Falcon army, being its highest-ranking member in that game and the leader in command of the first alien invasion attempt on Earth in 2633 A.D.

He is actually identified as two separate entities; his head and upper body are known as "Emperor Demon Dragon God Java", while his heart is known as "Gomeramos King".


Emperor Demon Dragon God Java is an enormous worm-like alien creature that in 2633 invaded planet Earth. He was the commander of the intergalactic army known as Red Falcon in that campaign, being its highest-ranking member. However, it was later revealed that the real purpose of this "invasion" actually wasn't to conquer the planet, but to retrieve an artifact of great power that had been stolen by the humans from a shrine belonging to them on Jupiter. Java and his army came to Earth inside a giant meteorite that crashed near the Galuga Archipelago; they took control of the largest island and brainwashed the local military force so they would follow their orders.

The Federation sent two commandos from the "Contra" task force to infiltrate and stop the invading forces; their names were Bill Rizer and Lance Bean. Both soldiers alone successfully managed to neutralize the controlled local army and the aliens, and ultimately breached into their nest, which happened to be a gigantic biomass that actually comprised Java's own body. After successfully defeating Java's upper body, they delved further inside his organism until they reached his still living heart, which after one last ditch and desperate struggle, was also destroyed.

Other invasion attempts commanded by other alien leaders followed after this defeat, with Java (or other creatures of the same or similar species) included within their ranks, although never again seen having a commanding role over their forces.



In the original Contra, the game's final stage as a whole is considered to be the entire alien entity that is Java, with the hero first battling his head and then, at the stage's conclusion, his heart. Throughout the series, Java is usually depicted as a large worm or dragon-like alien head. He vomits an endless supply of Bundles (flying and persistent grub-like creatures that attack the player). The player is obstructed by a mount of immovable boulders (or skulls) and cannot progress to the next corridor until Java has been destroyed.

In most cases, after Java has been destroyed, his body remains functioning, controlled by his still living heart, which the player has to destroy. This alien organ is characterized for covering up an entire wall, pulsating rapidly as it provides life to the rest of the biomass. This alien usually has a set of alien eggs surrounding it on both ground level and ceiling as a last means of defense/offense against potential threats, which release an unrelenting hoard of scorpion-like creatures.

Contra III: The Alien Wars[]

Java made his first reappearance in Contra III: The Alien Wars, where he appears as one of the many minibosses that are fought throughout the last stage. While both of his forms –head and heart– do appear, and the level's layout is similar to that from the first game, he is neither a primary antagonist nor does it necessarily mean that his heart is providing life to the rest of the biomass. In fact, no plot involvement was given to him in any of the sequels, being relegated to appear only as a recurring miniboss, which could imply the possibility that he is just an individual of an entire species of giant worm-like alien creatures.

Contra: Hard Corps[]

Main article: Java/Hard Corps]]

Contra: Hard Corps continued to reimagine Java's appearance through dramatic alterations, this time being much more mobile and somewhat resembling either a fish or a frog, and as such, having visible eyes for the first time, and now bearing a more developed and much longer arm (which it actually uses to attack). He appears as a miniboss near the end of the Alien Space optional final stage. This could imply that this is a different species or subspecies of Java created through genetic tampering from Colonel Bahamut's inexperienced team.

Contra: Shattered Soldier[]

In Contra: Shattered Soldier, there are two boss enemies that resemble Java:

  1. Gluttonous Ugougo: A giant eel-like serpent creature encountered in the underground meat processing facility of the City stage that spends most of its time eating shredded meat, completely independent of a heart.
  2. Tissue Helminth: A long earthworm-like creature fought in the Archipelago stage that was the result of Lance Bean fusing with an alien embryo that he somehow implanted into his body.

The reason why these two creatures look different from one another is probably because they represent different species under a singular genus, or perhaps two different species that could possibly share a connection to the original ancestral Java. The latter is most likely based on Lance's own memories of the beast and therefore he may have made "altercations" to the creature similar to the Gomeraos King battle prior.

Regional differences[]

See also: Gava (regional differences)

Given that character names and storylines are often changed or altered when a product is released between different countries, it's not rare that continuity differences may occur. The term "Red Falcon" in particular is heavily affected by this. Because the original Japanese storyline for the franchise envisioned Red Falcon only as an alien/terrorist organization and not an actual living entity, there is no legitimacy on what Red Falcon's true appearance is meant to be in the West.

Due to liberties taken when the first games were localized in North America, both Java and Gomeramos King –the two creatures the player faces at the end of Contra– were generally considered to be components of "Red Falcon"'s physical form, thus making this name refer to both the army and also its leader. However, in the original Japanese storyline, the two creatures –already being given names of their own (which never made it to North America)– only make up the leaders of the Red Falcon army. Furthermore, the final boss of Super Contra, Gava (initially known in North America by the name of Jagger Froid), who is stated to be the real leader of the alien army, is also commonly confused with the supposed western leader "Red Falcon".

All this brought a major inconsistency in the North American localization of Contra III: The Alien Wars, when Java, until then known as "Red Falcon", made a reappearance in the game's final stage (probably the reason why he was renamed "Para-Slug"). However, in Japan all the names remain consistent throughout the series.



IGN ranked Red Falcon 76th being one of the Top 100 Villains due to his persisting resurrections.[5]


  • In Contra, Java takes damage from weapons at all times, including when the mouth is closed. In all other reappearances of Java, the creature can only be damaged when the mouth is open.
  • In the Game Boy port, Contra: The Alien Wars, three Javas are fought in the final stage; the additional two make up for other missing minibosses from the original version of that level: Gomeramos King and the Metal Alien.


Screenshots and sprites[]



  • According to the accepted canon, Java, along with its heart Gomeramos King, died in 2633 A.D., putting with this an end to the first alien invasion, although he reappears numerous times throughout the series as a recurring boss. Whether this means he was revived, reborn from alien cells, there are more than one of these alien creatures, or if they are just a reused concept with no involvement in the later games' storylines, is uncertain.
  • In some titles, this alien abomination has appeared with a drastically different design, size and body shape, implying that the name "Java" could refer to a genus of large serpentine aliens and not just the same creature, with its diverse incarnations probably being identified as different species.
Chestburster - 01

A chestburster from the Alien series.

  • Java's general physical appearance appears to be inspired by the chestburster from the Alien science fiction-horror film franchise.
    • In Contra III: The Alien Wars and Contra Returns, the alien head form is slightly altered through the addition of tiny arms; as a result, his appearance loses some resemblance to the iconic film creature. The changes to his design were likely done to avoid potential lawsuits from 20th Century Fox, the company behind the Alien films.
  • Despite being referred to as a male in gender, Java is capable of giving birth by vomiting his offspring out into the world. His overall shape (and subsequent renaming in Contra III as "Para-Slug") may suggest his physiology is similar to that of a gastropod, thus bearing hermaphrodite characteristics.
Contra Rebirth Level 4 Boss 1

Giant Stone Head from Contra ReBirth.

  • In Contra ReBirth, there is a miniboss called the Giant Stone Head which is apparently inspired by Java, probably being a reinterpretation of him for that game. As its name implies, it is a giant statue head –similar to Java's upper body– that vomits dark orbs that float about, somewhat replicating the behavior of the Bundles Java spews out.
  • Java, the final boss of Contra: Operation Galuga, mixes elements from the original Demon Dragon God Java, as well as from Emperor Demon Gava, combining both into a new, single character. Physically, Java in Operation Galuga resembles the original Java to some extent, with its head having a worm-like structure and seen from the side, but attack-wise, it more closely resembles most Gava fights from previous titles.
