Nexon

Background
Nexon is a South Korea-based video game company founded in 1994 (did not use a logo until 2003) by Kim Jung Ju and Jake Song, with its main headquarters being moved from Seoul, South Korea to Tokyo, Japan as of 2011. The company is known for its biggest-hit game, MapleStory.

1st Logo (2003- )
Logo: On a white background, we just see a geometric shape with a dark blue trapezoid, a cyan triangle, and a lime green rhombus. Under it, there is the logo's name in a Jetix-like font.

Variants:


 * There is an earlier variant where we see a blue girl jumping and then turning lime green once she walks into the door-like shape.
 * There is also a MapleStory variant (from 2009 - 2015?) that shows two green creatures, one with a viking helmet running away from a Ribbon Pig stampede, and another one in a cowboy hat riding on one of said mobs. The name is next to the shape instead of under it.

Trivia: In the MapleStory variant, the Ribbon Pigs are a type of monster in said game.

Technique: None, but the variants are animated.

Music/Sounds: A synth-like chime. However, in the MapleStory variant, there is a childish tune with some high-pitched screams of the green creatures and the Ribbon Pigs stomping. In the MapleStory 2 variant, the original version of the tune plays, but is remixed with a xylophone-like chime.

Availability: Very common. It is seen on many Nexon games, especially MaplestoryM, the mobile port of MapleStory. However, the MapleStory and the early variants are ultra rare (bordering on extinction) depending on the version of a Nexon game you have, since the games force you to update them.

Legacy: The logo is fondly remembered among many Nexon game communities, especially MapleStory.

2nd logo (2016- )
Logo: In a black background, we see the lime green "door" opening in a crate-like fashion while "glowing" in a white color. The logo's name later appears, but in white text and is next to the shape instead of under it, just like in the MapleStory variant.

Technique: Just the white glow and opening of the "door". Pretty simple but decent animation.

Music/Sounds: An elevator-like remix of the MapleStory variant from the 1st logo.

Availability: Uncommon, as this is seen on Counter-Strike Online if you live in South Korea or have a Korean CSOnline game client.
