Hal Emmerich (ハル・エメリッヒ Haru Emerihhi), nicknamed Otacon (オタコン Otakon), is a fictional character from Konami's Metal Gear series. Created by Hideo Kojima and designed by Yoji Shinkawa, Otacon was introduced in the series in Metal Gear Solid.
In Metal Gear Solid, Otacon, an ArmsTech employee who designed Metal Gear REX, becomes a close ally of Solid Snake upon learning of REX's nuclear strike capabilities. After the events of Metal Gear Solid, he helped Solid Snake form Philanthropy, a group whose main objective is to prevent proliferation of Metal Gear-type weapons. Snake and Otacon infiltrate the military installations and facilities of the world, delving into their compounds through stealth and cyber hacking. In a sense, Snake is the brawn and Otacon is the brains behind "Philanthropy."
A devoted fan of anime, Hal's chosen nickname is the short form of the Otaku Convention, with reference to Otakon held in Baltimore each year. The name "Hal" is a direct reference to the computer HAL 9000 from the film 2001: A Space Odyssey, one of several references to the film which is present in Metal Gear Solid; in the Otacon ending of the game, Hal and Snake make direct comparisons to the film.
Time...its supposed to heal our wounds
Joy...I never knew till I met you
On that summer night in the moonlight
When you were there by my side
Peace...it only comes when I have you
(when I have you)
If you put your arms around me
I can never (ever) let you go
If you put your arms around me
I can never (ever) let you go
Love is the only thing that I have left
And now I know Im no better than the rest
And I try and I try to win you back
With every line in my heart and mind dream
Of the time when you were by my side
If you put your arms around me
I can never (ever) let you go
If you put your arms around me
I can never (ever) let you go
Never let you go
Never let you go, no, no
Never let you go
Never let you go
Oh no, no
Never let you go
If you put your arms around me
I can never (ever) let you go
If you put your arms around me
I can never (ever) let you go
If you put your arms around me
I can never (ever) let you go
If you put your arms around me
