Double Knockout: His battle with the Dan Ketch/Noble Kale Ghost Rider seemed to be a Mutual Kill but vengeance spirits and angels are hard to kill, even for each other.
Nineties Antihero: Has become one because of retroactive continuity, though almost all his major enemies being worse than he was makes it a little easier to swallow, there are still some really questionable things he did in older comics.
Color-Coded for Your Convenience: When Zarathos came back, was retconned into a good at heart angel and started making Blaze's Ghost Rider more like his, Dan's dropped Noble Kale and got a new spirit with blue flames so the two could be told apart more easily.
Flechette Storm: The chain was initially unique to him and he still possess a greater control over it than the other riders, even to the point of breaking it into its individual links and launching them as a cutting barrage.
Mistaken Identity: Blaze attacks him because he thinks he is Zarathos, the demon that Mephisto put in him, then helped Dan with his situation to make up for it. Dr. Strange and Nightmare also attacked him for the same reason. Vengeance comes after him thinking he is John Blaze.
Mode Lock: Blackout tried to kill him by ripping his throat out. All that did was force him to become the Ghost Rider permanently and thus give him more incentive to kick Blackout's ass.
Curse: As a result of both Uriel and Mephisto claiming his soul he's forced to wander between the worlds a spirit. He typically possesses the first born of a certain family to turn them into Ghost Riders, becoming a kind of curse to them too.
It Runs in the Family:The mother of John Blaze and Dan Ketch. A descendent of Noble Kale, as well as his last host before Dan Ketch.
Out-Gambitted: She manages to make Mephisto swear to end "The Curse of Noble Kale". Mephisto instead sticks Zarathos in John. Naomi tried to fight Mephito but he kills her and lets Nobel find his way into her younger son Daniel, since Noble's "curse" was to enter the first born of the generation it technically had ended.
Spanner in the Works:After death her spirit continues to subtly mess with Mephisto and Blackheart's plans.
Killed Off for Real: So it seems. A spirit of vengeance that looks suspiciously similar to his shows up overseas and but doesn't act like him, suggesting Michael is still dead and it has found a new host.
Unwitting Pawn: As caretaker explained, he sold his soul to Mephisto for power he was already going to get anyway. Blackheart also mocks him for being easy to manipulate.
Curbstomp Battle: John and Dan, for different reasons, were not as powerful as Ghost Riders when they started out as they were later in their careers. Alejandra was at full power from day one and had a habit mowing through their old enemies and people they wouldn't have been able to beat head on. She nearly kills Skadi, which would have ended the Fear Itself crossover before it began. This stops once she runs into Blackheart though.
Our Angels Are Different: He looks less like any popular depiction of an angel or the way they were described in scripture and more like a bigger, stronger, more complete version of the Ghost Rider, which made sense with where Noble Kale's story was going. It makes even more since with later retcons, what doesn't is why the angels introduced after him are standard winged humanoids.
Buried Alive: There are apparently many evil beings trapped beneath his cemetery, the man eating people of dust are confirmed to be down there because they temporarily escaped and tried to eat the Night Stalkers.
Dimension Lord: Of one of the splinter realms, which he patterns after hell as described in The Divine Comedy.
Enemy Mine: He is willing to help the Ghost Riders against common threats, though he rarely gets involved directly.
Exact Words: Mephisto will follow the word of his deals, and will go out of his way to violate the spirit of the deals.
Such when he pits Blaze and Zarathos against Asmodeus, saying they would be freed from each other if they managed to outrace him but if they weren't fast enough to win they'd have to serve Asmodeus. Ghost Rider wins the race but Mephisto finds some reason to back out of the deal. Ghost Rider was really bait to get his rival to accept a small fine, Mephisto might consider being blasted into non existence "small" (see Fighting a Shadow below) but it probably wasn't what Asmodeus had in mind.
Fighting a Shadow: He will always come back as long as his dimension is still around. A powered up Alejandra came close to killing him for real.
Satan: He's not the Satan, there are many wannabes who have equal claim to that title (equally invalid claims) but Mephisto is generally the most used stand in with only one or two people introduced so far who are maybe more legit.
Smug Snake: Sort of. While he's certainly very, very powerful and competent and has a not-insignificant amount of major accomplishments to his name, he also likes to act like he's a far bigger deal than he actually is, as beings like Chthon, Set, and Dormammu greatly dwarf him in power and potential reach (he generally accomplishes far more than they do, but that's because they're either locked away or act on a far larger scale, which understandably takes more time and effort).
The Chess Master: He will often allow himself to be beaten if he can use the event to give a greater enemy more grief down the line.
Villain Override: Not usually, but he did resort to it once when he felt a witch had failed him badly enough.
Made of Evil: Centuries worth of sins collected from the "Christ's Crown" area were used by Mephisto to bring him to life. This is what makes him immune to the penance stare, experiencing all the evil he's caused doesn't really bother him since he's made of the stuff. He can still be hurt by simpler, more direct methods though.
Manipulative Bastard: He spends surprising little time getting his own hands dirty, despite saying that Mephisto is too passive.
Hired Guns: He works as an assassin, muscle or whatever else you pay for.
Name's the Same: Blackout also what an insane Nova villain is called. That one manipulates the dark force dimension but like this one also had an Unexplained Recovery after civil war.
Scars Are Forever: Averted but he did hold a grudge against Ghost Rider for burning his face(because he was dumb enough to try and bite a flaming skeleton).
Starter Villain: For Dan Ketch, introduced in issue #2 of his book. Blackout really wasn't a big threat to Ghost Rider then and Ghost Rider only got stronger as his story went on through the midnight sons arc while Blackout's been stagnant.
And Your Little Dog Too:Tries to kill Dan Ketch and his already hospitalized sister because of their connection to the Ghost Rider.
Evil Tastes Good:If anybody ever deserved to die by the penance stare, it was him. He feeds off of other people's pain though so Ghost decides to just kill him in a more simplistic manner. Alejandra later shows the penance stare is capable of hurting him but also ends up settling on a more simplistic finish.
First Law of Resurrection: Ghost Rider kills him, yet he shows up again after Civil War. Two of his minions did want to resurrect him but didn't know how and since they haven't showed up since it is doubtless the writers even remember.
Ghost Memory: He can see another person's memories by drinking their blood.
Impaled with Extreme Prejudice: When Ghost Rider finally catches him. It doesn't kill him but slows him down enough to be caught in an explosion that took out the building they were in. Unfortunately for Ghost Rider, that didn't kill him either. Seems Dan Ketch and Kale weren't too familiar with vampire weaknesses.
Misanthrope Supreme: He didn't choose to become a vampire, but this is why Steppin Razor decided to turn him.
Not Quite Flight: As a member of the Varnae/Dracula line of vampires, he can turn into mist but he also has a nonstandard ability to levitate. Not enough to really fly but enough to stand on and jump off things that really shouldn't support his weight.
Atlantis:She hung around there long ago but was banished long before its sinking.
Summon Bigger Fish: This was accomplished by calling on Tiamat(or the Leviathan, depending on whose penciling the story) and having her(or it) eat Lilith.
Big Bad: She is what drove the midnight sons together.
Composite Character: The primary source seems to be the Akkadian Kisikillillake but she also draws from various Sumerian Lilitu and depictions of Lilith in Judo-Christian apocrypha, including not being the only one.
Deflector Shields: To the point she can cover the moon and isolate entire nations from the rest of the Earth!
Totally Not a Werewolf: She has pale skin and drinks like a vampire so some have mistaken her for one. She is also known for attempting seduce people in their dreams, which leads some to mistake her for a succubus. She's worse than both.
Our Vampires Are Different: She was also accused of being involved in the creation of the vampires belonging to Varne's line(more commonly known as Dracula's line).
Composite Character: Of the various Ba'als, Ba'al Hadad is where his powers come from, the blood spilling of his followers comes from Ba'al Hammon, the association with the Gehenna refuse dump is probably from Ba'al Berith or Ba'al Peor and the degeneration into a demon is of course from medieval demonology.
Demonic Possession:Not often, he only did so out of necessity when most of his body was destroyed.
Eviler than Thou: The tetrarchs of entropy, old foes of the Avengers, briefly show up while he is trapped in the same dimension they are and try to escape at the same time he does but Ba'al shoves them back in. This did not turn out so well for him later when a Windigo sided with John Blaze against him. Ba'al would not have had any trouble defeating Blaze if he was alone, since Blaze could not become a Ghost Rider at the time.
First Law of Resurrection: God gave mankind the ability to kill him and the deed was done. Then he showed up again because an author still wanted to use him.
Hell: Just for pun, the actual valley of Gehenna was where the Hand Of God beat him down. Gehenna being a garbage dump site that was metaphorically compared to hell.
Totally Not a Werewolf: The Ba'alim, his followers, are known for drinking blood and are sometimes granted special powers but they are not vampires.
Back from the Dead: Does this for people in mass when he gets out of hell. He does this just to have bodies though, he does not have as much use as one would think for their identities or anything.
Batman Gambit: He tortures those in his hell even more than just being there already does to give them more incentive to escape, figuring maybe if someone else manages to get out, he can follow them. It finally works when he snares a Ghost Rider.
Bigger Bad: Somehow his activities fall under the radar during Civil War and World War Hulk, even though he could do more damage than both combined.
Cold-Blooded Torture: Besides having demons tear apart John Blaze every day, he also forced Greexix to deepen a pit for the rest of eternity. When an accident causes Greexix to go blind though, Lucifer decided to torture him for real. After Zadkiel's attempt to take over heaven gets him sent to hell, Lucifer takes joy in torturing him too.
Mother of a Thousand Young: Possibly a father, he's supposedly created numerous demons but it can be reasoned he's not the source of all of them, maybe not even the original source of them but who knows.
Name's the Same: The X-men fought an alien who happened to be named Lucifer, in fact that alien is responsible for putting Charles Xavier in a wheelchair. He is a dangerous villain in his own right but not to be mistaken for the angel that started a war in heaven and is now bound in hell.
Not So Different:Tries this on Ghost Rider after they end up in the spot where Blaze made his deal with Mephisto.
Number of the Beast: Since his re-entry to Earth split him into six hundred and sixty six different fragments, which is just fine with him, as he isn't omnipresent. The Ghost Rider sets about destroying all the fragments but each time one is killed, all the others get stronger, Lucifer figuring he will eventually be powerful enough to defeat whoever targets him. If the fragments aren't killed off, he gets to cover more ground.
Satan: He claims to be but many other lords of hell dispute it, some have apparently been at it longer than him. The fact that many religious scholars (even in real life) argue that Lucifer and Satan are not the same entity doesn't help.
Ironic Hell: After getting kicked out of heaven he wanted to become the lord of hell but unlike everyone else competing for that title he can't escape his own realm without help. Even when he gets out, he's effectively trapped as soon as someone sticks him back in. Even his former subordinate and fellow fallen angel Asmodeus had more freedom than him in this regard, despite being much weaker.
Cessation of Existence: He goes about wiping people on Earth out of existence to prove his godhood to other people.
Dark Is Not Evil: He leads a squad of Black Hosts, large dark and intimidating figures who look like many depictions of fallen angels. But only the ones he leads are bad, most of them are good guys despite their appearance.
Infernal Paradise: With Zadkiel in charge heaven is worse than any hell anyone else had managed to come up with.
Manipulative Bastard: By way of retroactive continuity he could be argued to behind Lilith's release and the Midnight Sons story arch, as well as the cause of the depression that allowed him to manipulate Dan in his own story arch.
Our Angels Are Different: He isn't as odd looking as Zarathos or Uri-El but not as pretty as the angels introduced between them and him like Ruth.
Fallen Angel: He may be evil, he may want to take over heaven for himself, but he's still dedicated to slaying demons and the forces of hell.
Rewarded as a Traitor Deserves: He rebelled against heaven along with Lucifer but then betrayed Lucifer and sided back with heaven. His peers were not impressed and demoted him from the rank of Arch Angel.
The Captain: He used to be in charge of the spirits of vengeance as well as a black host.
