Who am I? Challenge Game

[Team Farrell]

Mick Foley?

He obviously wore a mask. He had Cactus Jack, Dude Love and Mankind who weren't related -- they were him. And he won the world title when he left the Corporation and went out on his own.

[PEN15v2]

No.

1 - Once known for wearing a mask.
2 - Was once thought to be part of a wrestling family, but wasn't true
3 - Gargano talked about "betting on yourself" last night (and 9 months ago before he left, but this isn't part of the clue), and this person bet on themselves and won their first World title because of it.
4 - It wasn't the WWE/WWF title

Jimmy Jack Funk

[PEN15v2]

No sir.

Weird how short a time Undertaker wore a mask, yet its still remembered. Interesting how the short timed things stand out

[Powder]

Is this Hulk Hogan?

People thought for years that he and Beefcake were brothers...
He briefly wore a mask as Mr. America...
He won his first title, which was the IWGP Heavyweight Championship (original version) in 1983 after he took the role of Thunderlips in Rocky 3, where Vince didn't approve and bet on himself to take the role, and it launched him into the Stratosphere.
The IWGP title is from Japan.

If clue 2 is not meant literally then I can make an argument for Cody Rhodes.

[Powder]

If it is Cody, I will be pissed at myself, b/c I originally thought it was him. But what family was he part of that wasn't true?

And double checking dates, Cody left WWE in May 2016, and won the NWA title in September 2017, over a year later, so the 9 months doesn't fit.

[PEN15v2]

Not Cody (though, follow this wavelength), not Hulk.

Also, corrected the typo and clarified a clue since the 9 months part wasn't really a factor in it.

[BK-097]

Hmmm...I'll give this another crack. Rick Rude

EDIT: I rescind my guess of Rick Rude!

Going with Christian Cage

[PEN15v2]

1 - LOS CONQUISTADORS!
2 - Once thought to be brothers with Edge, but then became his best friend
3 - In 2005, bet on himself by turning down a new WWE contract, signed with TNA, and within 5 months was NWA World Champ.

[BK-097]

That was a good set of clues...the family thing had me hung up for a while.

1) I come from a wrestling family
2) If not for the whispers of Pat Patterson, my career may have looked quite different
3) I debuted an eventual WWE Hall of Famer

[Powder]

The Rock.

[BK-097]

Sound logic, but not the Rock. I think trying to be sneaky may have led me down a road of missing something obvious.

EDIT:
1) I come from a wrestling family
2) If not for the whispers of Pat Patterson, my career may have looked quite different
3) I debuted two eventual WWE Hall of Famers

[Powder]

Kurt Angle?

His brother Eric was in wrestling for a time.

[BK-097]

Not Angle.
