Onyxia making her first appearance in "World of Warcraft's" Dustwallow Marsh is HNGN's Throwback Thursday selection for Aug. 13 for her immediate impact that is still dominant in the game today.

"11 years ago today, Onyxia made her first appearance in Dustwallow Marsh. Happy birthday, broodmother! #TBT," "World of Warcraft" said on Twitter about the swamp, which is located in the middle of the Kalimdor continent, according to Wow Head.

"August 12, 2004... Onyxia's Birthday. The final model was still not complete. Roman Kenney would later build the model that went into the final game. I placed Onyxia and Geoff Goodman designed the fight," said Jeffrey Kaplan, game director and vice president at "WOW's" developer, Blizzard Entertainment.

The woman is known as the "bloodmother," who takes care of Black Dragonflight dragons from the Azeroth kingdom that live in her hiding place, Wow Head reported.
