History Characters / HearthstoneHeroesOfWarcraftBosses

* PuzzleBoss: The Heroic version of this boss has you start with the white king and a deck of only fifteen cards, representing a regular set of chess pieces, and your hero power is only good for repositioning your pieces.
* TheComputerIsACheatingBastard: The Black King's hero power is literally called Cheat, whereupon he instantly kills any minion on your left side of the field. This trope is even truer in Heroic mode, where you are saddled with only fifteen cards in your deck, but the Black King still commands the same thirty-card deck he uses in Normal.

* ZeroEffortBoss: Unintentionally; later updates to the game broke the Temple's AI and made it never use its Hero Power. As such, the only threats you encounter are the 10/10 statue (which is destroyed when the ceiling collapses 1 turn later) and, if you chose the shortcut, the War Golem, which will only do a combined total of 24 damage even if you do nothing for the entire fight.

When confronted at the top of Icecrown, the Lich King less blatantly overpowered, though he still does begin with 30 armor and health, and opens with a unique spell based on the player's class to give them a hard time. His initial Hero Power summons a 2/2 Ghoul. Once he hits 7 mana, he equips Frostmourne, swapping his board for six 2/6 Trapped Souls. His Hero Power for this phase becomes Soul Harvest, making him and Frostmourne immune while he controls a Trapped Soul. Once the Trapped Souls are destroyed, his final Hero Power is Remorseless Winter, which is free and deals 1 damage to the player, while increasing in strength each time he uses it.\\

** Not only is it impossible to mill his Frostmourne, causing him to overdraw on turn 7 (when he plays it) will cause him to get stuck in his second phase, making it virtually impossible to defeat him.

One of the minions raised by the Lich King was the Crypt Lord Anub'Rekhan. In life, he was one of the nerubians' most powerful lords. Now, he guards the doors of the Arachnid Quarter. His hero power summons a 3/1 nerubian for 2 mana, and this is bumped up to a 4/4 nerubian on heroic.

As a playable card, Professor Putricide is a 4 mana 5/4 Hunter Legendary that sets a random Hunter Secret in play whenever the player plays a Secret.

Deathbringer Saurfang is also a Legendary 5-mana 3/5 Death Knight minion with Taunt that requires 2 Blood Runes. When killed, his Deathrattle returns him to the player's hand, and makes him cost health instead of mana to play again.

As a playable card, Lana'thel is a 5 mana 1/6 with Lifesteal who gains an extra attack for each card the player has discarded through the course of the current game.

As a playable card, Sindragosa is a 8 mana 8/8 Mage Legendary that summons 2 Frozen Champions - 0/1 tokens that add a random Legendary minion to the player's hand when they die.

Patchwerk is a unique encounter in that he starts out fatigued with no cards to draw, and only a 5/8 hook weapon in play (4/8 Windfury in heroic), the hook replenishing itself when it runs out of charges - mirroring the straightforward nature of his encounter in Videogame/WorldOfWarcraft. His hero power in both modes is a 4 mana 'destroy a minion' ability, rendering him able to remove your big taunters to continue wailing on his face.

Thaddius himself is not a collectible minion. Instead, the collectible Feugen and Stalagg have Deathrattle effects that spawn Thaddius as an 11/11 token after they both die.

Deathwhisper's hero power damages your minions until they have 1 health. She begins with 90 armour over her 30 health, but you begin with Valithria Dreamwalker on your board, a 30/5 dragon that cannot attack or be attacked while she's injured.

* BossBanter: The bosses freely talk during the fights.

[[folder:Tutorial Bosses]]

* TheComputerIsACheatingBastard: Played for Laughs with Illidan, and some others have a few blatantly over-powered cards.

* TheComputerIsACheatingBastard: Mukla's Big Brother is blatantly overpowered, weighing in at a massive ''10/10'' for 6 mana. Fortunately, you have ways to stop it. Namely punching Mukla in the face.

* UnusableEnemyEquipment: Many of the bosses use '''Deathcharger''', a low cost minion that damages its owner when it dies, and '''Necroknight''', a mid-range minion that destroys adjacent minions when it dies. These can make the enemy HoistByTheirOwnPetard. There's also '''Skeletal Smith''', a mid-range minion that destroys the opposing hero's weapon when it dies.

* SkillGateCharacter: The random legendaries given by Prince Malchezaar are generally far better than what a player with a limited collection has in their deck, but once you expand your collection, they're instead more likely to simply make your deck less consistent due to simply not synergizing with the rest of it.

A hideous bone amalgamation reportedly made from the remnants of The Lich King's duplicate cards. Marrowgar's hero power allows him to fully heal himself for no mana. In addition, he summons Bone Spikes, 0/8 minions that deal 15 damage to the player at the start of Marrowgar's turn.

Saurfang is The Lich King's favourite Legendary, according to him. He only has 20 health, but his hero power protects him from all damage except damage from weapons.

In game, has a hero power that can kill players instantly. However, he starts with Moira Bronzebeard, his wife, as a minion, and while she is alive, his hero power cannot be used. The challenge, as a result, is to kill the boss without getting Moira killed, and absorbing her damage (Taunts and [=AoE=] are generally out as a result.\\

As a card, Emperor Thaurissan is a 6 mana 5/5 that reduces the cost of all of the cards in your hand by 1 at the end of your turn.

Baron Geddon is also a collectible Legendary from the Classic set. He's a 7 mana 7/5 that deals 2 damage to all other characters at the end of your turn.

* UnusableEnemyEquipment: '''Burning Adrenaline''' a free spell that does 2 damage to the enemy hero.

* HoistByHisOwnPetard: His hero power attempts to do this by supplying him with random spells from the player's class to make the player taste their own medicine.

* UnusableEnemyEquipment: The '''Cauldron''' is technically this, a 0/5 with Taunt that changes Sliterhspear's Hero Power and gives you Sir Finley. In addition, there is '''Slithering Archer''', a 2/2 for 2 mana that deals one damage on Normal and two damage to all enemy minions on Heroic. He also has '''Slithering Guard''', a 5 mana 3/6 (5/7 on Heroic) with Taunt.

An animated suit of armor that Rafaam puts in your way after you deal with Skelesaurus Hex. It's Hero Power prevents it from taking more than one damage at time. On Heroic, this effect applies to it's minions also.\\

* EasterEgg: Playing Lord Jaraxxus against Malchezaar will result in a brief exchange between the two Eredar. After that Jaraxxus sings some "karaoke" , using [[NoIndoorVoice the only way]] [[HollywoodToneDeaf he knows]]

* EvilIsPetty: His entire motivation in the adventure is that ''he's pissed because he didn't get an invite''. Taken up a level once Medivh defeats him, pulling a TakingYouWithMe and potentially ruining the entire party.

Magtheridon has also been made into two collectible cards. In ''Ashes of Outland'', he's a 4 mana 12/12 neutral Legendary that begins Dormant, and summons three 1/3 Hellfire Warders for the opponent. Once all three Warders are killed, Magtheridon awakens and destroys all other minions. In ''Whizbang's Workshop'', Magtheridon, Unreleased is an 8 mana 12/12 Legendary neutral Mech/Demon that begins Dormant for 2 turns. While Magtheridon, Unreleased is Dormant, he deals 3 damage to all enemies at the end of your turn.

Blackrock Spire honeycombs the heights of Blackrock Mountain, and serves as the first line of defense against those who would dare intrude on Blackwing's domain. Nefarian’s forces now occupy the former Dark Iron dwarf citadel, with the likes of ogres, orcs, and dragonspawn patrolling its halls.

The Omnotron Defense System was once a plaything of the Dark Iron dwarves left forgotten in Blackrock’s depths. Nefarian has taken to tinkering with them, and he's adjusted his pet project's "Murder" setting to 11.\\

Magtheridon is also a collectible card. He is a 4 mana 12/12 neutral Legendary that begins Dormant, and summons three 1/3 Hellfire Warders for the opponent. Once all three Warders are killed, Magtheridon awakens and destroys all other minions.

* DynamicEntry: He enters the final boss fight with 8 mana, and will immediately spend it all on [[KillEmAll Twisting Nether]].

* SequelDifficultySpike: To compensate for the lack of a Heroic mode, the base adventure is much more difficult than its predecessors, and the final battle with the Lich King is a strong candidate for the single toughest boss in the game. That said, unlike the previous adventures, Icecrown Citadel does ''not'' lock you out of any content if you can't beat it - the most valuable item (the free Death Knight) is given to you after the first fight, with the rest of the rewards merely being 3 packs and the [[CosmeticAward Arthas hero skin]].
