Umbridge refers to the fictional character Dolores Umbridge, a malevolent, uptight, and pink-garbed villain in the Harry Potter series.
For her, pink is an affectation as false as her laugh and her kittens. It is the colour of Valentine's Day, of love and romance. It is also a colour – rightly or wrongly – with girlish, sweet associations, and it is perhaps this that Umbridge wishes to project when she insists on dressing herself head to toe in it.
With the fall of Lord Voldemort, Dolores Umbridge was put on trial for her enthusiastic co-operation with his regime, and convicted of the torture, imprisonment and deaths of several people (some of the innocent Muggle-borns she sentenced to Azkaban did not survive their ordeal).
After only a short time at Hogwarts, the Ministry of Magic expands the Pink Professor's role at the school: "Having already revolutionized the teaching of Defence Against the Dark Arts, Dolores Jane Umbridge will, as High Inquisitor, have powers to address the seriously falling standards at Hogwarts School."
Epilogue. After the war ended, McGonagall was fully instated as the Headmistress of Hogwarts and was awarded the Order of Merlin, First Class by new Minister for Magic Kingsley Shacklebolt.
The Head of Slytherin is Horace Slughorn (who left the role to Severus Snape for fifteen years before taking it up again in 1996) and the House's patron ghost is the Bloody Baron.
Umbridge is more evil , she tortured many of the students while Bellatrix tortured a few and talk about the personality , Umbridge is both sadistic and selfish while Bellatrix is only sadistic.
Harry describes Umbridge to Sirius Black, saying that she's vile enough to be a Death Eater, despite not being one. Umbridge is also depicted to be a prejudiced person, despising half-breeds and Muggle-born witches and wizards to the point of firing Hagrid due to his half-giant birth status.
Bellatrix Lestrange was Lord Voldemort's equal in cruelty, if not worse than him. She was unparalleled when it came up to committing some of the most horrible acts of cruelty and destruction. She truly belonged to the Dark side and loved to embrace it.
Green is the colour of much 'Dark' magic; of the 'Dark Mark', of the luminescent potion in which Voldemort conceals one of his Horcruxes, of many 'Dark' spells and curses, and of Slytherin house.
She has an affinity for this horrible object, which would help rather than hinder her." Suggesting that while the locket does have a negative influence, Umbridge has always been an awful person - the horcrux only enhanced the terrible personality she had already.
Yup, that's right: when the Death Eaters killed Mad-Eye, and then took over the Ministry, they apparently gave Mad-Eye's "mad eye" to Umbridge. Who then installed it in her door to use as a way of spying on her fellow wizards.
Andromeda married a Muggle-born, Ted Tonks, and was subsequently disowned by the Blacks, whereas Narcissa, conversely, married Lucius Malfoy, heir of a wealthy pure-blood family; thus, Bellatrix is the aunt of both Nymphadora Tonks and Draco Malfoy, respectively.
Peter Pettigrew
He definitely ranks at the top of those who should be regarded as the most evil members of the Death Eaters, if for no other reason than that he was more than willing to betray Lily and James to their certain deaths at Voldemort's hands.
Peter Pettigrew (a.k.a. Wormtail) is the only Death Eater known to have been in a House other than Slytherin (Gryffindor) while at Hogwarts. There, he was a close friend of Sirius Black, James Potter, and Remus Lupin, although he was the least intelligent and least talented of the group.
Cedric's death is a major plot point in the stage play Harry Potter and the Cursed Child, in which Harry and Ginny Weasley's son Albus uses a Time-Turner and prevents Cedric's death. Due to his humiliation in the Triwizard Tournament, Cedric eventually becomes a Death Eater and kills Neville Longbottom.
Harry himself is a half-blood, since his pure-blood father, James, married a Muggle-born witch named Lily, and his maternal grandparents were Muggles.
Lord Voldemort (Ralph Fiennes), aka Tom Riddle, was described by Dumbledore as one of the best students ever to graduate Hogwarts as well as "the most dangerous Dark wizard of all time." Before he had even learned about the existence of the Wizarding world, he was terrorizing his fellow orphans with impressive but ...
1 Lord Voldemort
Lord Voldemort is the scariest villain in Harry Potter, if only because he is the series' overreaching villain who successfully evades death more than once.
Moaning Myrtle
Born in the late 1920s to Muggle parents, Myrtle Warren started her Hogwarts life in the early 1940s, where she was sorted into Ravenclaw.
Horace Slughorn (1997 - present) Horace, after being convinced by Dumbledore and Harry Potter, returned to Hogwarts as the Potions master. After Severus killed Dumbledore and became headmaster of Hogwarts, it was decided that Horace was to become the Head of Slytherin House once again.
The most likely reason why Lord Voldemort's nose disappeared and he devolved into such an evil-looking creature is that as he dabbled deeper into the Dark Arts, his appearance gradually became as distorted as what remained of his twisted soul.
