"You are armoured by the Emperor himself. Righteousness is your shield, Faith your armour and Hatred your weapon. So fear not and be proud, for we are the sons of the Sanguinius, the Protectors of Mankind. Aye, we are indeed the Angels of Death."
— Blood Angels Chapter Master Dante
The Blood Angels is a series of novels and short stories by author James Swallow. The Blood Angels are a Warhammer 40,000 chapter of Space Marines, and the novels cover the early history of the Chapter and more specifically, the stories of Battle-Brothers Arkio and Rafen as Arkio declares himself to be a reincarnation of the Chapter Primarch, Sanguinus. Later novels Black Tide and Red Fury deal more with the Chapters ongoing struggles with its own flaws, the Red Thirst and the Black Fury, which at times threaten the purity of Battle-Brothers and could bring about the collapse of the Chapter as a whole; either through an inability to sustain the losses suffered due to the latter or through the former being perceived as the Taint of Chaos on them and their successor Chapters.

Please resist the urge to put examples on this page or link to this page on tropes unless you are citing from 40K novels in which the Blood Angels feature. Examples which are specific to rulebooks or other i-universe fluff should go on either the 40K page or in the Space Marines section of the Imperial factions page.
Beauty Equals Goodness: Played straight with Sanguinius. Subverted with Arkio, where it's a sign of Chaos corruption.
The Berserker: Every Blood Angel Space Marine is susceptible to this (excluding Mephiston or is it?), providing much bait for excessive Wangst. Fortunately the author sidestepped it.
Berserk Button: Well, actually, most of the time they are not sure what do it, but it happens.
Beware the Nice Ones: The Blood Angels are one of the nicest chapters of Space Marines, but if they hit the Black Rage or Red Thirst, then Emperor have mercy on you, because the Blood Angels won't.
Bishōnen - The default Blood Angel Warrior is an impossibly-handsome paragon; his appearance modified by inheriting the literal genes of their Primarch Sanguinius. It's an important part of the fluff, Baal and it's moons are death worlds devastated from total war, most of it's inhabitants are severally scarred by radiation.
Bittersweet Ending: Deus Sanguinius: The Blood Angels lose dozens to the Arkio Insurrection and the subsequent Black Rage Malfallax causes, and Rafen is forced to slay Arkio, but the Blood Angels alive who followed Arkio are restored to the Chapter, the planned Civil War within the Blood Angels is averted, and Arkio is implied to have gained the Emperor's forgiveness.
Blessed with Suck: YMMV, since the Flaw is exactly what is destroying the Chapter, it's what makes it so strong.
Bling of War: Like all Space Marines, but given that Sanguinius took it a little further than the other Primarchs, it's only fitting that the Blood Angels take it a bit further than most Astartes, as they dress their Captains and Sanguinary Guard in gold armour. Arkio causes a bit of a buzz when he says he wants gold armour as well.
Blood Magic: Blood Boil, The Blood Lance and The Sanguine Sword Psyker Powers.
Cain and Abel: Only IN SPACE!, sort of reversed, its still fratricide only the killer is upholding God's will (sort of) and the dead brother was literally turning into a Demon and both of them are unbelievably awesome badasses.
A little more fitting is Horus and Sanguinius themselves. Horus and Sanguinius were described as being closer than any of the other Primarchs, enough that both tried to sway each other from their own side of the Horus Heresy. In the end, Horus (the elder, in a sense) slew Sanguinius, fitting this trope to a tee.
Death Seeker: Once you fall into the Black Rage, you can never climb back out barring a miracle. Those that succumb are put into a separate unit and unleashed in suicide attacks.
On Shenlong, people begin actively seeking the "murdergift" of being killed by the Blood Angels. They probably didn't even object when Mephiston ordered the planet subjected to Exterminatus.
Dying Chapter: The Flesh Tearers due to their recklessness in combat and higher than normal black rage fall rates, they can barely recruit enough replacements, even after Seth's work they can only maintain four companies.
Fantasy Counterpart Culture: Of various eras of Italy for the most part. Many characters have either Roman or modern Italian-sounding names, a penchant for renaissance-style finery and their armor is often decorated with Gino-esque gold chains. They also have some Romanian/stereotypical Vampire influences.
Fearless Fool: Actually subverted on Cybele, where the Blood Angels admit that after seeing so many of their comrades fall to the black rage, they are afraid.
Feel No Pain: Part of the army uniqueness. The Sanguinary Priests brings Furious Charge and Feel No Pain to those close to them.
First Blood: Goes to Rafen when he manages to cut Arkio's wing when the fight on Sabien. Arkio's followers are not happy. It's especially jarring to Sanchiel because as a Sanguinary Priest, he knows blood like few others. And he knows its tainted from the smell.
Forbidden Chekhov's Gun: The Black Rage is generally a bad idea. However, in order to use the full power of the Spear of Telesto, Rafen embraces it willingly and does not lose his mind.
Lightning Bruiser: Space Marines are this. The Blood Angels are even more. When not acting as Terminators, their First Company acts as Assault Marines.
Losing the Team Spirit: The deaths of many of the angels at the hands of the black rage. It takes a suicide suggestion to get Turkio to even consider a last stand, let alone an attack. The others refuse to join even this in a Not So Stoic moment.
Macross Missile Massacre: One of the Apocalypse's Formations is this. You need three Stormravens, and they fire all their Blood Strike missiles at once.
Magic Knight: Mephiston, Chief Librarian of the Blood Angels. His powers serve only to make him faster and hit harder.
Blood Angels Librarians and Dreadnought Librarians.
The whole army can be this, it helps they have a army-wide Feel No Pain rule.
Mêlée à Trois: The battle between those still loyal to the God-Emperor and those now following Arkio is complicated by Word Bearers.
Also occurs in Black Tide, with Rafen, his Blood Angels/Flesh Tearers kill-team and the other Space Marines imprisoned in Bile's fortress on one side, against both Fabius Bile and the New Men, and an army of feral Tyranids.
Napoleon Delusion: Those who suffer the Black Rage believe that they are Sanguinius at the final battle with Horus during the Heresy. This makes them unable to be reasoned with, but utterly unstoppable on the battlefield unless killed.
Nice Guy: Sanguinius is one of the nicest primarchs during the crusade era. The Chapter as a whole, when they're not succumbing to psychotic rages, also wears this hat.
Not So Stoic: In the opening of Deus Encarmine, Space Marines confess to being afraid to face their foes, after the horrific attack on their fellows.
Not Using the Z Word: "Vampire" has been used by detractors of the Blood Angels since the Great Crusade; as such no Blood Angel will utter the word. Nevertheless, Rafen immediately makes the connection when he sees Arkio being corrupted by Chaos.
The term is also brought up when describing the Bloodfiends in Red Fury.
Orbital Bombardment: Used twice in the Deus duology. Early in Deus Encarmine a Word Bearer warship obliterates the Blood Angels' motor pool with an orbital attack. Deus Sanguinius closes with the Angels' brass mentioning in a regretful tone that they'll have to call for an Exterminatus against Shenlong.
Phlebotinum-Handling Requirements: The Spear of Telesto will refuse to activate for anyone who does not carry the genetic markers of Sanguinius (i.e. just the Blood Angels and presumably their successor chapters).
Power Gives You Wings: Subverted with the Sanguinary Guard. They don't get real "wings", but Jump Packs decorated with them. They are also the uttermost elite force of the Chapter.
Praetorian Guard: Honour Guard. Also the original purpose of the Sanguinary Guard for Sanguinius.
