Realy? Regulus is a great guy!

Umbridge. The subtle pure-blood supremacy and Muggle-born hatred seems very Salazar-y.

Tom Marvolo Riddle is most like Slytherin, thats why he is the heir...

Yes, he is the most like Slytherin but he's the heir because he's related to him

Slughorn, because he gives the true explaination that slytherins dont have to be bad like bellatrix and voldy moldy, but be cunning and ambitious in wat they do. that they strive for what they want

But that's the house, not the person

The person is the original head of the house, so the house is like the head, the house and head are the same, so

^i disagree. The head and the house arent the same

Ex. Godric was brave, but wormtail was a coward.

And salazar DID have the pure-blood mania voldemort and the death eaters had. But most slytherins after the second wizarding war didn't. (Ex. scorpious malfoy, and he's literally a malfoy)

^100000% agreed

Lucius is as sly and nasty as Salazar, who defenitley was a bigot and nasty, but not as evil and psychopathic as Voldemort
