History ComicBook / Grendel

* AnythingThatMoves: Crystal Kennedy.
** Her grandfather's pretty close, too.

* BladeOnAStick: Hunter Rose's 'fork', a weapon also favored by Christine Spar and Eppy Thatcher

* ChivalrousPervert: Orion Assante is a more literal version of this than most, being the closest the series has to a genuine BigGood and also very much in requited love with [[BrotherSisterIncest his half-sisters]].

** Grendel Tales back covers feature a motif of the symbols of individual Grendel clans. One of them is clearly based on [[IconicLogo Japanese mon]].

* {{Cyborg}}: A few characters have cybernetic implants, such as Captain Wiggins' artificial eye. CyberneticsEatYourSoul comes into play more than once. Taken UpToEleven with Grendel-Prime, who is a full-body conversion ''powered by sunlight.''

** Anyone with a SkunkStripe is probably a major Grendel figure.

However, this is not the end of the story; the series proper is set in the future after the conclusion of ''Devil by the Deed'', initially featuring Stacy's daughter Christine Spar. The story then continues in the far future, where the concept of Grendel eventually becomes the basis of world civilisation.

* WithGreatPowerComesGreatInsanity: Lots, including Captain Wiggins, Brian Li Sung, Laurel Kennedy and Abner Heath.

* TheGreatPoliticsMessUp: The USSR still exists in 2120, at which point the simultaneous assassination of its Premier and the US President leads to WorldWarIII.

** HideYourLesbians: Crystal Kennedy essentially has Susan exiled to the Dakota compound so she can take up with a new (male) love interest.

* {{Omnibus}}: The early 2010s saw the publication of the complete series (minus the ''Batman'' crossovers for legal reasons, and the Argent origin story because it was impossible to obtain high-enough-quality artwork) in four omnibus volumes, in order of internal chronology.

** Later in the series, the vampire population explosion started by Pellon Cross's indiscriminate siring habits clarifies several details about vampires in the world of Grendel: each one can assume a single animal form, called a 'totem', that reflects his or her personality; they don't bleed unless they'd previously been hemophiliacs, in which case it makes them ravenously hungry; they can subsist on blood from animals or dispensed by machines; they share Tojiro's vulnerability to water, which can kill them in sufficient amounts; and, while sunlight couldn't kill Tojiro (probably due to his age), younger vampires dislike it so much that they prefer to live far from the equator.

* OurVampiresAreDifferent: The "rules" of vampirism in the series are closer to those in the original ''Literature/{{Dracula}}'' than many later elaborations.

* FullConversionCyborg: Grendel Prime, at the time he's first introduced, is little more than a head and upper torso with mechanical limbs. By the time of ''Batman/Grendel II'', his only remaining human parts are his brain and eyes. The intervening events are described with gruesome BodyHorror in the prose novel ''Grendel: Past Prime''.

* AfterTheEnd: The ''War Child'' continuity clearly takes place in a post-apocalyptic world. Most of the Middle Eastern OPEC states are now an abandoned wasteland, and Europe is shown to consist largely of bombed-out ruins.

* ThoseTwoBadGuys: Cross's minions Zebra and Kiersch.
