Hybrid Heaven

Hybrid Heaven was one of the very few RPGs released for the Nintendo 64. It was made by Konami and released in 1999.

You play as Diaz, a genetically modified being created by aliens to assist in their mad plot to take over the world. You quickly learn the horror of your misdeeds and seek to bring down this alien organization from the inside, saving the world in the pro--

Oh, wait, that's not right.

No, it turns out that you're not Diaz at all. You're actually Johnny Slater, Secret Service agent extraordinaire, kidnapped by aliens and disguised as Diaz to prevent the evil alien menace from making a clone of the President and using him to take over the world.

The story isn't the most original thing in the world.

What is original about the game is its unique combat system. When engaging in a fight with an enemy, you and your opponent immediately put up your dukes and begin circling around each other. You navigate a series of menus to determine if you want to punch, kick, or throw the enemy, and then you go on to specify exactly what kind of punch, kick, or throw you want to use. It's a rather interesting blend of an RPG/Fighting/Wrestling game. Additionally, while your character does level up in a traditional RPG style, he also levels up in several other ways. The various moves that you use also level up to increase their power, and all of the limbs that your character uses in combat level up their offense or defense depending on how often you use them/how often they get hit.

Despite this interesting system for combat, it's very easy to recognize that the game is quite flawed. Outside of combat, the character can be rather difficult to control, and most of the game consists of little more than running down dozens of similar-looking hallways, blowing up robots, and occasionally fighting a new enemy. But it's entertaining.

The game was released to rather average reviews and scores, and would probably have completely disappeared from peoples' memories were it not for the fact that it is one of only a handful of RPGs released for the N64.

This game contains examples of:

 * Artificial Stupidity: Given that most of the enemies follow their routines to a fault, some of them may become suicidally obsessed with doing something that leaves them wide open, and will keep doing it until they succeed. The worst example is the foes who just suddenly decide that they must grapple with you, and won't stop trying no matter how many times you shatter their kneecaps and send them flying.
 * Boss in Mook Clothing: Gacrux. Dear God, Gacrux. The game recognizes it as a normal enemy, but many people have less trouble with some bosses than they do with this monster. It has excellent stats, a breath weapon (meaning you have to spend the entire fight standing right next to it to keep it from using said weapon), and can charge up his attacks ridiculously faster than you can. Last but not least, its bladed arms are all but impossible to block.
 * Bullfight Boss:
 * Crosshair Aware: One of the two boss fights that do not utilize the combat system has a crosshair following you, telling you where the monster's fireballs are going to land.
 * Dual Boss: A boss fight that does not involve the game's normal combat system has you fighting two enormous monsters at once. Well, not so much fighting them as running away from them and using trickery to beat them both.
 * Escape Sequence: The entirety of the second level of the game consists of you running away from an enormous monster. And it's the kind of escape sequence where, every time you think you've gotten away from it, the monster returns by coming through a secret door or coming down an elevator.
 * Evolving Attack: Part of the RPG mechanics of this game is this, with you gaining more attacks both from leveling up your body parts and receiving attacks you don't have from enemies. It even works with the secret "Combo Attacks"... if you can figure out how to do them.
 * Exponential Potential: By the end of the game, depending on how many moves you learned from enemies, you might have around 70 different moves at your disposal, spread amongst punches, kicks, and wrestling moves. It is extremely unlikely that you will be using all of them evenly in combat.
 * Mirror Boss:
 * One-Hit Kill: There is a rare item you can collect in the game called the Ring Eraser. When you use it in combat against a non-boss enemy, it instantly ends the fight by causing your enemy to fade out of existence. Predictably, you don't get anything from beating foes with it.
 * Our Presidents Are Different: Several varieties, all technically personified within the same person.
 * Rule of Cool: Fighting aliens isn't anything new, but fighting them with punches, kicks, and wrestling moves while they fight back the same way? Win.
 * Sequential Boss: And how! The final sequence of the game has you fight a whopping six boss fights in a row with no opportunity between fights to save or heal. Three of the bosses are technically different forms of one enemy, and the other three are all individual enemies. Hope you saved up your healing items.
 * Stellar Name: Every single enemy in the game (with the exception of the human hybrids and the Master) is named after a star.
 * Subsystem Damage: In combat, individual body parts can be damaged on both you and the enemy. A damaged body part cannot be used in combat, and if the legs are damaged, then movement is slowed. Additionally, if the head is damaged, then the character is considered to be unconscious and can do little more than sit back and let the opponent beat the somewhat-living crap out of it.
 * Suddenly Voiced: Throughout the entire game, the protagonist does not say a single word, and it seems like he is your standard Heroic Mime. Then, during the ending cinematic, he suddenly starts talking (with full voice acting!) as if he'd been doing it the entire time. It's actually pretty jarring.
 * Take Over the World: Played horrifyingly straight. No reason is ever given for why the villains want to take over the world. They just do.
 * That One Boss: Hybrid Heaven has quite a number of boss fights, and it's likely that every single one is That One Boss to someone in the world. Here are some reasons why:
 * Some of the bosses don't follow the same rules of movement during combat as you. Usually, when you select a move and the enemy is out of range, you simply make the attack and strike nothing but air, missing and making yourself look like an idiot. In the case of these enemies, they can select the attack, move closer to you, and then start the attack proper. Many of the bosses have unique abilities, such as using a force push-style attack to knock you off your feet, using breath weapons on you, or turning invisible. Nearly every human boss you fight in the game carries a gun. While fighting said boss, moving too far away from them will prompt them to pull out their gun and start blasting away at you, meaning you have to spend virtually the entire fight staying no more than a few feet away from them and well within range of their melee attacks.
 * "The Reason You Suck" Speech: The Hybrids have this in spades. Not only are they all amazingly over-confident in their invasion plans of taking over the world (except for perhaps Anna, the most loving Hybrid, and Diaz, who doesn't really care about the invasion and simply wants to kill Johnny), but they all always and continuously complain about how the human race is so inferior to them, and their only apparant reason for wanting to take over the Earth is because they think they're better than everyone else. Not only that, but each of the leaders keep continue telling Johnny that he is fighting for worthless humans, and that he should be dead. Also, it seems that no matter how much ass Johnny kicks, how much of the plan is ruined because of him, and just how much they underestimated him, the Hybrids continually shrug this off and when the leaders fight Johnny themselves, they still think they'll win and be able to go on with their invasion (which by this point is obviously SNAFU), and even when the invasion is completely and totally beyond FUBAR, The Dragon says everything is going as planned. When it comes to over-confident villians who don't even take a hint when their main enemy has single-handedly destroyed their base, ruined their invasion, saved the president, and aborted their whole friggin' species, the Hybrids play this very straight.
 * Wrestler In All Of Us: Yes, one of your primary methods of attacking your alien enemies is by wrestling them. While some of these moves are simple suplex and chokehold moves, there are many more that would have absolutely no place in real combat, and oddly enough, seem to actually require the cooperation of the opponent to carry out.
