'''Pyrovores''' are a [[Tyranid]] unit that were once widely considered to be the worst unit in all of [[Warhammer 40,000]]. In D&D terms it's the True Strike of Wargaming.

They look almost identical to Biovores (a unit that is a cheap source of assault pie plates that can also be used as a barrage, and has one of the derpiest faces around), but they have a much newer, much less [[derp]]y model (although their gun does look strangely like an [[Slipshine|erect throbbing penis]]). As such, pretty much everybody buys the Pyrovore models and uses them as Biovore. But this has the possible side effect of convincing GW that the Pyrovore is actually good... | |||
Also they make for great [http://www.wobblymodelsyndrome.com/comic-166.html new years eve fireworks.] | |||
==Why were they so bad?== | |||
Alright, spleen's been vented enough, so let's get real for a moment. | |||
The biggest problem comes down to the fact they're in the Elites slot, which is ''easily'' the most jam-packed slot in Tyranids. They're competing with: '''[[Hive Guard]]''' (who are good at taking down transports and one of the best shooting units in the 'Dex); '''[[Zoanthrope]]s''' and their '''[[Neurothrope]]''' brood leaders (incredibly powerful [[psyker]]s that can throw down an ABSURD amount of mental [[dakka]] each turn); '''[[Venomthrope]]s''' (an excellent support unit that provides mobile cover, defensive grenades, and hilarious 2+ Poisoned attacks); '''[[Malanthrope]]s''' (quite powerful in their own right but [[Forge World]] only); '''[[Lictor]]s''' (who, while not being particularly good, can at least claim their ability to not have Deep Strikers who land within 6" of them scatter); '''[[Haruspex]]es''' (while not particularly good, at least competent enough); and '''[[Maleceptor]]s''' (who... well alright, they're pretty shitty but not as bad as Pyrovores). | |||
Additionally, they have one of the most schizophrenic loadouts in the game. It can ignore armor saves (and hit at S5) by dropping its attack stat to 1... but with only one attack per model, and the rest of their stats make them absolutely ''awful'' in close combat, including I2 and WS3. They're too slow to keep up with an assault-based army, and largely pointless there anyway since once the rest of your army gets in close, there's nothing left to flame; in a shooting army they compete with Hive Guard (which are basically the only way 'Nids can take down light vehicles efficiently). Their Flamespurt ability is AP 4, meaning you can't take out [[MEQ]] with it. They can explode, which could see them used as a suicide unit... except that affects ''your'' units as well. Your pitifully weak, vulnerable-to-AoE-explosions units, Plus it's only when Instant Death is inflicted, which means melta or krak missiles... but it dies much easier to massed bolter shots. On top of that, good luck just getting the damn thing in close enough to actually have it affected. Not to mention that wasting an extremely valuable Elite slot on a expensive-for-its-cost suicide unit is just stupid. | |||
The wording of its exploding ability is so poorly written that when the rules are applied exactly as written, whenever one suffers Instant Death, ALL UNITS ON THE BOARD suffer a number of hits equal to all non-Pyrovores within D6" of it. This means that the Pyrovore is so bad its abject shittyness transcended its rules and altered the minds of its writers to make it even worse. Exact text: | |||
"Volatile: If a Pyrovore is slain by a Wound that inflicted Instant Death, every unit suffers a Strength 3 AP- hit for each model (excluding Pyrovores) within D6" of the slain Pyrovore (resolve damage before removing the Pyrovore as a casualty)." | |||
Presumably what they wanted to write was that each model within D6" suffers a S3 AP- hit. Meaning that for a squad of 10 Guardsmen next to the Pyrovore, they suffer 10 hits. What they instead wrote means that ''every unit on the board'' suffers 10 hits. Theoretically hilarious if you had a way to detonate it intentionally and brought nothing but T6 - but you don't. | |||
So, all in all, the worst fucking unit in the game. Completely pointless, no idea where it wants to be, competes with '''good''' units (units that are basically compulsory if you want Tyranids to win). The other thing is that it had '''never''' been good: it was bad in the previous Codex (where it debuted) and it was bad in 6th, too. Countless ideas are thrown about to unfuck the unit, and you can almost see how it's suppose to work: Tyranids have trouble dealing with things in cover, and this thing is made to deal with things in cover -- so perhaps if they were beasts, had higher WS, BS, and Initiative and were allowed to fire the flamespurt in close combat like a [[lizardmen|stegadon?]] But the cocksucking piece of shit is fundamentally contrary to the basis of the entire army. To make it fit, [[homebrew]]ers have pretty much had to make the pile of fail unrecognizable from its origins. It is ''that'' bad. | |||

However, their form of accurate deepstrike got lost, forcing them to trudge across the board and retain the reputation they had. | |||
But now that they have that deep strike option back combined with their 6th ed improvements, paying 220 points isn't that bad for 9 wounds worth of reasonably durable heavy flamers (which people will hesitate to try and ID that close to their troops) backed up with an effective gun platform in the Tyranocyte. With the default pressure from very common standard stuff like flying Hive Tyrants, Mawlocs, more Tyranocytes filled with Devilgaunts or other Monstrous Creatures, they stand a very high chance of being left alone to wreak havoc multiple turns. | |||

That's right, proud winner of "41st millennium's worst unit" for years is now much more viable, with the stats of an heavy flamer mounted on a melee fighter that hurts ENEMY units when taking damage in close combat and packs rather nasty CC attacks as well, and has a range that's coincidentally just long enough for it to attack as soon as it gets out of a Tyrannocyte.

 Expect huge amounts of derp and rage, punctuated by /tg/ extracting humor from it. |
Pyrovores are a Tyranid unit that were once widely considered to be the worst unit in all of Warhammer 40,000. In D&D terms it's the True Strike of Wargaming. Introduced in 5th Edition, they were representative of Robin Cruddace's awful, awful Tyranids codex, in which at least half of the units had absolutely no idea what they're supposed to be doing or were so abysmally awful at what they were supposed to be doing that no one ever took them.
Also, put it in TF2 context for a bad time.
And then the 6th edition book came out, and, somehow, Pyrovores got even worse.
But by some miraculous act of the Emperor, GW (Mostly) isn't shit anymore and has recognized the uselessness of the Pyrovore. The 8th edition changes finally made the Pyrovore into a surprisingly decent enough murder machine, and 9th edition made them even better.
Fluff[edit]
Pyrovores are living fuel refineries for the Hive Fleet. They gain said fuel by eating. They can pretty much eat anything, from organics to inorganic material like rocks or metal, which they're able to digest thanks to the corrosive acids inside their stomachs, which explode if they get bumped too hard. Or, if you enjoy the taste of brain bleach, they're giant walking prematurely-ejaculating penises with fire instead of spunk.
A Pyrovore has two brains: one for that lumbering hunk of fail that eats like an obese kid, and another for the giant Flamespurt Cannon on its back. This allows the Pyrovore to devour everything like a neckbeard eating meatbread while the cannon keeps watch. The funny thing about this is that its cannon is much smarter than the beast itself; the Pyrovore is only driven by its need to eat while the cannon's smart enough to target enemies on its own. This might very well explain why the Pyrovore's terrible in melee combat.
Why the Hive Fleet thought it was a good idea to put a derp-grade brain into a beast that needs a modicum of intelligence to handle itself in combat, especially given its ability to explode, while putting the smart brain on a gun, which really isn't that powerful compared to the other morphs, and make them incapable of working together, begs the question: why?. Sure, it can be vaguely likened to how a tank is naught but a giant moving hunk of metal without the operator's driving acumen, but even that proves flimsier than one would like.
How Bad Is it?[edit]
5th Pyrovores are worse than Old One Eye, a DISTRACTION CARNIFEX special character in a codex that hates DISTRACTION CARNIFEXES, who is renowned for costing MORE than a Land Raider and dying to a stiff breeze... but at least he has a general idea of what the fuck he's supposed to be doing and would be tolerable if he was cheaper.

Does this thing Shit out the 'nid equivalent of baby formula?
"Saving Graces"[edit]
They look almost identical to Biovores (a unit that is a cheap source of assault pie plates that can also be used as a barrage, and has one of the derpiest faces around), but they have a much newer, much less derpy model (although their gun does look strangely like an erect throbbing penis). As such, pretty much everybody buys the Pyrovore models and uses them as Biovore. But this has the possible side effect of convincing GW that the Pyrovore is actually good...
Also they make for great new years eve fireworks.
Why were they so bad?[edit]
Alright, spleen's been vented enough, so let's get real for a moment.
The biggest problem comes down to the fact they're in the Elites slot, which is easily the most jam-packed slot in Tyranids. They're competing with: Hive Guard (who are good at taking down transports and one of the best shooting units in the 'Dex); Zoanthropes and their Neurothrope brood leaders (incredibly powerful psykers that can throw down an ABSURD amount of mental dakka each turn); Venomthropes (an excellent support unit that provides mobile cover, defensive grenades, and hilarious 2+ Poisoned attacks); Malanthropes (quite powerful in their own right but Forge World only); Lictors (who, while not being particularly good, can at least claim their ability to not have Deep Strikers who land within 6" of them scatter); Haruspexes (while not particularly good, at least competent enough); and Maleceptors (who... well alright, they're pretty shitty but not as bad as Pyrovores).
Additionally, they have one of the most schizophrenic loadouts in the game. It can ignore armor saves (and hit at S5) by dropping its attack stat to 1... but with only one attack per model, and the rest of their stats make them absolutely awful in close combat, including I2 and WS3. They're too slow to keep up with an assault-based army, and largely pointless there anyway since once the rest of your army gets in close, there's nothing left to flame; in a shooting army they compete with Hive Guard (which are basically the only way 'Nids can take down light vehicles efficiently). Their Flamespurt ability is AP 4, meaning you can't take out MEQ with it. They can explode, which could see them used as a suicide unit... except that affects your units as well. Your pitifully weak, vulnerable-to-AoE-explosions units, Plus it's only when Instant Death is inflicted, which means melta or krak missiles... but it dies much easier to massed bolter shots. On top of that, good luck just getting the damn thing in close enough to actually have it affected. Not to mention that wasting an extremely valuable Elite slot on a expensive-for-its-cost suicide unit is just stupid.
The wording of its exploding ability is so poorly written that when the rules are applied exactly as written, whenever one suffers Instant Death, ALL UNITS ON THE BOARD suffer a number of hits equal to all non-Pyrovores within D6" of it. This means that the Pyrovore is so bad its abject shittyness transcended its rules and altered the minds of its writers to make it even worse. Exact text:

What they instead wrote means that every unit on the board suffers 10 hits. Theoretically hilarious if you had a way to detonate it intentionally and brought nothing but T6 - but you don't.
So, all in all, the worst fucking unit in the game. Completely pointless, no idea where it wants to be, competes with good units (units that are basically compulsory if you want Tyranids to win). The other thing is that it had never been good: it was bad in the previous Codex (where it debuted) and it was bad in 6th, too.

But the cocksucking piece of shit is fundamentally contrary to the basis of the entire army. To make it fit, homebrewers have pretty much had to make the pile of fail unrecognizable from its origins. It is that bad.
Or is it?![edit]
With the return of our beautiful Mycetic Spore (now called the Tyranocyte) in the Leviathan Supplement, Pyrovores now actually stand a chance in filling a niche in your army as an effective stealth and shrouded eradicator! A very specific niche, but a niche nonetheless!
"But wait, PyrovorefanXX1!" you ask. "Pyrovores could do this in the old codex but were still classified as 'cess, what's changed now"? Well firstly, Pyrovores did get buffed!
