Mundungus Fletcher

Mundungus Fletcher, known as "Dung" to his acquaintances, was a disreputable wizard who dealt in stolen goods and operated on the fringes of wizarding society. Despite his criminal tendencies, he served in both the first and second Order of the Phoenix, though his loyalty was frequently questionable.

Appearance

Mundungus was distinctly disreputable-looking:

Short, squat build
Long ginger hair and a droopy besom-like moustache
Bloodshot baggy eyes
Typically wore filthy, tattered clothing
Reeked of stale sweat, tobacco, and alcohol
Resembled a disreputable dog according to some descriptions

Criminal Activities

Mundungus made his living through various illegal enterprises:

Dealt in stolen goods and contraband
Sold items of dubious legality
Traded in magical creatures and items
Ran various scams and cons
Operated a thriving black market business
Frequently mentioned "business opportunities" that were transparently illegal

Relationship with Dumbledore

Despite his flaws, Mundungus owed Dumbledore:

Dumbledore had helped him avoid Azkaban in the past
This created debt of gratitude Mundungus took seriously
Served in Order primarily out of loyalty to Dumbledore
Dumbledore trusted him despite his criminal nature
Their relationship showed Dumbledore's tendency to see good in everyone

Order of the Phoenix Service

Mundungus's Order work was mixed:

Tailing Harry: Assigned to watch Harry at Privet Drive during summer before fifth year. He abandoned his post to pursue a business opportunity, allowing Dementors to attack Harry. This nearly got Harry expelled and Mundungus in serious trouble with the Order.

The Seven Potters: Participated in the plan to move Harry by disguising himself as Harry with Polyjuice Potion. When Voldemort appeared, Mundungus panicked and Disapparated immediately, abandoning Mad-Eye Moody, who was killed as a result. This betrayal earned him universal contempt from Order members.

The Theft from Grimmauld Place

Mundungus's most significant crime against the Order:

After Sirius Black's death, stole numerous Black family heirlooms from 12 Grimmauld Place
Sold them for personal profit
Among stolen items was Salazar Slytherin's locket (a Horcrux)
Sold the locket to Dolores Umbridge to avoid legal trouble
This theft inadvertently complicated Harry's Horcrux hunt significantly

Confrontation: When Harry, Ron, and Hermione tracked him down, Mundungus initially lied about the locket. Under interrogation and threats, he finally admitted selling it to Umbridge. His actions put the locket in dangerous hands and prolonged the war.

Character Flaws

Mundungus consistently demonstrated:

Cowardice in dangerous situations
Greed overriding loyalty
Inability to resist criminal opportunities
Willingness to betray trust for personal gain
Lack of shame about his behavior

Yet Some Redeeming Qualities

Despite everything, Mundungus had occasional moments:

Genuine loyalty to Dumbledore's memory
Did participate in dangerous Order missions
Eventually told the truth about the locket
Never actually joined Death Eaters despite opportunities
Showed guilt when confronted about his worst actions

Battle of Hogwarts

Mundungus's presence at the final battle was uncertain:

Not confirmed to have fought
Given his track record, likely avoided the battle
Consistent with his pattern of fleeing danger

Harry's Complicated View

Harry's opinion of Mundungus evolved:

Initially found him amusing in a disgusting way
Grew angry about the abandoned guard duty
Furious about Moody's death
Enraged by the theft from Sirius's house
Ultimately saw him as unreliable but not irredeemably evil

Post-War Life

Presumably returned to criminal activities
Likely continued operating on society's fringes
Whether he reformed after the war is unknown
