How about Bobby Hull?
Red Kelly was a golden gloves boxer. He rarely rarely fought but I have read a few accounts of him leveling others when it did happen.
He was the Gold Gloves Champion at St. Michaels College, he fought a lot in juniors until one of his coaches told him he was no good to the team in the Penalty Box.
I think he had about 7 fights that I could come across, and none of his opponents fared well. Kelly did a major beatdown on Vic Lynn in the 1950 Stanley Cup Semifinals he didn't have another fight until the 54-55 season. Kelly was not a hothead by nature but guys in the league did not tangle with him.
He racked up 15 (Two Majors and a misconduct) minutes in penalties when he tore into Eric Nesterenko on 16 October in Toronto during the 55-56 season (Read the Detroit Free Press article a few years back, will check the game log on the MB here to confirn) and he got into a doosey with Bert Olmstead in the 58 All Star Game,
As Gordie Howe stated in his biography: "Red was a Gold Glover, nobody messed with him".
A few others of note: Gilles, Beck, Craig MacTavish, Lee Fogolin.
Chara´s fight are pretty much the same.
If he meats a small guy he destroy him like .. I dont know like, but it is brutal. See Koci, Gionta or Dan Hinote (in Swedish league).
If he meats big feared fighter he uses his hand to keep the guy in the distance and with his second hand throw big punches with good timing. If Chara start to loose (because other big guy has good technique and balance) he tries to hang him down to ice what means victory or tie. His father was Greco-Roman wrestler who represented CSSR in 1976 olympic games, Chara knows how to get guy down on the ice, trust me..
If he meats guy with same size than we can talk about Chara´s technique, however that is impossible
I mean we will never know how good Chara´s technique really is, because his size is enough and when it is not, he hang other guy down on the ice what means victory or tie.
When he fought with Valabik it was probably the closest to his size category and Chara won. But Valabik is career AHLer with very bad skating so that doesnt count (and Slovak too, they probably had scary faces and during fight talked about summer in Slovakia)

“Let’s put it this way, no one wanted any part of ‘Si’ in a fight. Even Eddie Shore (Boston) and Red Horner (Toronto) steered clear of him, and Shore and Horner were considered the toughest guys in the League at the time," said "Ching" Johnson.
