Here are some of the games hardest bosses, or bosses that used to be impossible or near impossible.
Algalon the Observer
Backstory of Algalon
Loken's death triggered a failsafe mechanism warning the titans that Azeroth had lost
its foremost guardian. Algalon the Observer has been sent to examine the situation and,
if necessary, transmit a reply-code that will restructure the entire world, wiping out
all of its current inhabitants.
As Loken died, he alluded to a "herald" bringing an end to Azeroth. His death alerted the Titans that Azeroth's defenses had failed, as Watcher Loken was tasked with protecting the planet and guarding the prison of Yogg-Saron.
In response, the Titans sent Algalon the Observer to analyze the level of corruption in Azeroth and reply with status "Alpha" or "Omega." If status "Omega" is reported, the Titans will "re-originate" the planet, cleansing it of corruption— but also killing everything currently living on it.
Algalon is a hard mode-only boss in Ulduar, found in the Celestial Planetarium. Players have a one-hour window to defeat him per lockout period.
Some in-game Algalon Quotes:
Algalon_Summon03:
"It is in the universe's best interest to re-originate this planet, should my analysis find systemic corruption. Do not interfere."
Algalon_slay01:
"Loss of life unavoidable."
Algalon_Timer01:
"Analysis complete. There's a partial corruption in the planet's life support systems as well complete corruption in planet's defense mechanisms."
Algalon_Timer02:
"Begin up link. Reply code: Omega. Planetary re-origination requested"
Algalon_Death01:
"I've seen worlds bathed in The Makers flames. Their their denizens
fading without so much as whimper. Entire planetary systems born and
raised in the time it takes your mortal hearts to beat once.
Yet all throughout, my own heart, devoid of emotion of empathy,
I have felt.... NOTHING. A million, million lives wasted. Had they
all held within them your tenacity, had they all loved life as you do..."
Algalon_Death02:
"Translocation complete. Commencing planetary analysis of Azeroth."
Ragnaros
Background
The Firelord and his brethren once held sway over the entire world. As a servant of the Old Gods, he fought against the Titans for domination over the planet. The victorious Titans banished him and his brethren to the Elemental Plane - there to remain imprisoned until the end of time.
During the Elemental Sundering Ragnaros sought to consume Thunderaan, Prince of Air. Thunderaan fell, utterly defeated. The Firelord feasted upon the essence of Thunderaan, but was unable to consume him entirely.
Three hundred years ago, the ambitious and ruthless Dark Iron Clan initiated a war against their dwarven brethren, the Bronzebeard Clan and Wildhammer Clan. During this War of the Three Hammers, the Dark Iron Dwarf leader named Thaurissan lay siege to the Wildhammers' capital city of Grim Batol, destroying it. Despite this victory, the united Wildhammers and Bronzebeards were ultimately able to push the Dark Iron dwarves back to Blackrock Mountain. Thaurissan, seeking to summon a supernatural minion that would turn the tide of the war back to his favor, called upon the ancient powers sleeping beneath the world. To Thaurissan's surprise, and ultimately his doom, the creature that emerged was more terrible than any nightmare he could have imagined.
Now, freed by Thaurissan's call, Ragnaros erupted into being once again. Ragnaros' apocalyptic rebirth into Azeroth shattered the Redridge Mountains and created a raging volcano at the center of the devastation. Though Thaurissan was killed by the forces he had unleashed, his surviving Dark Iron Clan brethren were ultimately enslaved by Ragnaros and his elementals.
He and his dwarven minions took control of the Blackrock mountain's volcanic depths and made war on the orcs in the Upper Blackrock Spire, which served as the seat of power for Nefarian the Black Dragon. Ragnaros has uncovered the secret to creating life from stone and plans to build an army of unstoppable golems to aid him in conquering the whole of Blackrock Mountain.

Prince Thunderaan
Prince Thunderaan, as a character himself, can be brought back by players if they have certain items, these items were scattered across Azeroth to summon him, basically what is needed are his two halves of his prison and an energy source (Location not object.)
