Resurrecting dragons is passé. Resurrecting pro-wrestlers is where it's at.
Alduin? Pah! That puny weakling couldn't destroy a village, let alone the whole of Skyrim. If you really want something destroyed, you turn to someone more powerful, someone like the late great "Macho Man" Randy Savage.
The mod replaces Alduin with a warped, dragon-shaped version of the Macho Man, and the work of Skyrim modder "FancyPantz." As you can no doubt hear, Alduin's dragon speech has also been replaced with something more in keeping with Mr. Savage, namely, his trademark shout of "OOOH YEAH!"
If you were going to replace Aludin with anyone, the flamboyant Savage isn't a bad choice. Savage, who died in May of 2011, spent nearly 30 years in the ring, wrestling for the WWF - now the WWE - WCW, and briefly with TNA. He was the WWF and WCW heavyweight champion six times over the course of his career, as well as four times with other, smaller promotions.
