4: Glacier

One from WCW this time, and whilst he may not have been a huge star, there's no denying that Glacier left an impression with the crowd.
Decked in blue, with part of his face covered, the character was clearly a knock-off of Mortal Kombat icon Sub-Zero, with his fictionalized backstory even mirroring the video game character.

Interestingly, the costume for Glacier reportedly cost $35,000, and was designed by Atlanta-based AFX Studios, who would later go on to design Triple H's King of Kings entrance for WrestleMania 22.
Not just a costume, Glacier's entrance was also a sight to behold, as snow would fill up arenas when he arrived in 1996, with the man himself performing a backflip in the ring, before bowing to the ref.
Sadly, Glacier never won a championship in WCW, and thawed out in 1999, being released due to cost-cutting measures.
