Haku had a good first run with WWE in the 1980s as part of the infamous Heenan Family.
He made a name for himself as one half of The Islanders tag team before going on a singles run that picked up steam when he was given Harley Race's crown, recognized as the king of WWE.
Later, he became one half of the Tag Team champions with Andre the Giant, collectively known as the Colossal Connection.
Haku went to rival WCW where he changed his ring name to Meng and won the Hardcore title.
After not being seen in a WWE ring in many years, Haku was a surprise entrant into the 2001 Royal Rumble, and a good one at that. It looked like this would be the start of a great return for Haku.
But after a short-lived tag team with Rikishi, the return ended about six months later when the company released him.
Widely recognized as one of the toughest men in the business, he should have had more of an impact when he returned.
