Banglar

Banglar (バングラー) is the main villain from The Ninja Warriors and Aqua Jack.

Aqua Jack
In this game, Banglar is introduced as an alien invader who brainwashed an entire army with advanced arsenals. He uses his military powers to attack a city in an attempt to seize power, prompting the unnamed heroes to fight his forces. After the heroes fight their way through hordes of Banglar's military, they destroy the wall protecting Banglar's base, and proceed to invade his office and gun him down. However, the one they shot down is revealed to be a robotic double, as Banglar had already escaped the place, showing up on a screen and taunting the heroes from somewhere else.

The Ninja Warriors
Banglar is shown to have successfully seized power of the unnamed country where the game is set, becoming its president. He quickly turned the once prosperous nation into a nightmarish totalitarian state, oppressing and terrorizing people with his military forces and brainwashing them into submission. His forces employed not only military soldiers but also ninjas under his control.

A small resistance force, led by the charismatic Mulk, started a plan to overthrow Banglar's regime. They started developing cyborgs, which would be tasked with infiltrating Banglar's forces and assassinate him. The cyborgs, which were named the Ninja Warriors, were finally completed, and were about to enter the testing stage. However, the tide turned against Mulk, as Banglar's forces finally found his hideout and started attacking immediately. With no option left, Mulk decided to send the untested Ninja Warriors to fight. Their mission was to fight Banglar's forces and assassinate him.

In the Arcade game the Ninja Warriors successfully defeat Banglar's forces and invade Banglar's mansion, killing the now-defenseless Banglar. In the remakes Banglar escapes from his residence, thereby extending the plot. After fleeing from his presidential palace Banglar directs his forces from hidden military bases. Retreating to his final underground base, Banglar refuses to go down without a fight and puts up a last stand with his secret weapon along with his remaining soldiers. Desperate as Banglar was, he and his troops were ultimately no match for the lethality of conscienceless Ninja Warriors, and Banglar fell in the battle.

With Banglar dead, the Ninja Warriors self destruct, obliterating the entire base along with Banglar's corpse. Banglar's death causes a revolution, with Mulk becoming the new president. However, Mulk further develops his cyborgs, which in the end become a force far stronger than Banglar's military power. And so, history repeats itself.

Details
In all games Banglar appears as a fat man of medium stature, always dressed in a blue jumpsuit with a red tie. He is curiously depicted with having gray skin, pointy ears and red eyes, which hints at his implied extraterrestrial origins. In Aqua Jack his presence is only revealed in the game's ending, where he is seen on a TV screen.

In The Ninja Warriors, Banglar is treated as the game's last boss, even though he never actually fights. He only runs into a corner and stays there helplessly, dying in a single hit from the player. If the player turns his back on him, however, he will shoot a bullet at the player, though this causes minimal damage.

In The Ninja Warriors Again he is again the last boss. He never fights the player directly, however, instead he just stays seated inside of a domed machine while regular enemies constantly jump on the screen. The only way to break the glass dome is for the player to toss the enemies into it. Every now and then he will activate laser walls to the sides of his machine which damages both the player and enemies. The fight is much the same in The Ninja Saviors: Return of the Warriors, though due to the wider room not only there are more laser walls, Banglar can also activate a force field around his glass dome and he is aided by two laser turrets which move on the ceiling.
