Most Finishing Moves over a career

I think most guys' moves become iconic. Not sure why anyone would change their finishing move.

1 finishing move
Hogan: big boot and leg drop
Savage: double ax handle and flying elbow drop
Santana: flying forearm
Martel: Boston crab
Big Boss Man: boss man slam
Stone cold: stunner
Mr Perfect: perfect Plex
DiBiase: million dollar dream
Ric Flair: figure four

2 finishing moves
Shawn Michaels: weird back suplex, super kick
Bret Hart: back breaker and middle rope elbow drop, sharpshooter

It's like some guys need to add a new finisher when they are developing, they do.

I'm not a follower of modern wrestling, but did Edge always use the spear?

I think it would be a good gimmick for someone to have. Every week they have a different finisher, it fails to put the opponent away and the opponent wins the match. I'd watch that for a comedy bit. Maybe give it the gimmick to the following guys for each era:
- late 80s: Red Rooster
- early 90s: Tugboat
- late 90s: Marc Mero
- current: Mojo Rawley

Stone Cold had the stun gun, the million dollar dream, and the stunner

Hogan had Leg drop and the axe bomber (in Japan)

Randy Orton had the O-Zone then RKO then added the punt in (06?)

Yeah like alot of divas either use the bulldog or DDT... Just too common.

Also totally forgot about Jericho! Could even say he used the Enzuigiri for a little while as a finisher too.

Wasn't his original finisher the electric chair?

My vote goes with Big Show
Chokeslam / Showstopper
W.M.D - Weapon of Mass Destruction
Final Cut (Spinning headlock elbow drop)
Hog Log (spinning headlock legdrop)
Big Sleep
Spear
Colossal Clutch
Stinkface
Thrust Kick
Big Boot
Gorilla Press
Dropkick
Headbutt
Sidewalk Slam
Alley Oop
F5
"Frying Pan" chop

Did he have a punch finish move as well? Maybe it's listed there and I didn't know the name

Many of those weren't used to end matches though. If that were the case, many wrestlers could say a roll up/small package etc were their finishers too.

Hercules had a full nelson and the torture rack back breaker. He never seemed to use one after Power & Glory split up. He always seemed to lose and I don't recall him against any jobbers.
Warlord also had the full nelson as well as the running powerslam. Not sure if he used a powerbomb at some point somewhere.
Tatanka has the Samoan drop and then later that Wykea slam thing. Think he also used a top rope body press for a while.
Doink had the Whoopee Cushion and the stump puller.
Kane started with the tombstone and now uses the chokeslam.
There's Scott Steiner with his Frankensteiner, Steiner Recliner and some kind of falcon arrow.
Perry Saturn had a death valley driver and the Rings of Saturn.
Lita used a moonsault and the Twist of Fate.
Kurt Angle with his ankle lock and Angle slam.
Eddie Guerrero used a Gory Special, Gory Bomb and then later exclusively used the frog splash.
IRS started using a Samoan drop as the Write Off and then changed it to his flying clothesline.
Rey used a springboard huricanrana pin after the 619, before changing to the Dropping the Dime leg drop and then a frog splash or normal splash. Not sure what he used in WCW.
Benoit used a tiger suplex before the Crippler Crossface and probably a few other things.
Also Foley had his double arm DDT, mandible claw, Socko claw, Love Handle and Sweet Shin Music.
Rikishi had a big splash until he got too heavy and used a banzai drop and the Rikishi Driver.
I need a break now.
