Superman tries to stop him, but H'el turns out to be more powerful than Superman, Supergirl, and Superboy. How will they combat a threat this magnitude?H'el on Earth later gained a sequel story in the form of Krypton Returns.
H'el is rather nice to fellow Kryptonian Supergirl, who also wants to go back to her old life on Krypton. He later convinces her join him in his quest to resurrect Krypton, but manipulates her to estrange her from Superman.
H'el was also friendly to Superman, initially. When they first meet, H'el hugs Superman and even says he's like a brother. Superman was already suspicious, but then H'el offers to kill Superboy in front of him to prove his loyalty to Krypton (Kryptonians other than Superman are viciously racist against clones). Superman responded poorly to this.
All Your Base Are Belong to Us: In Superboy #15, H'el throws Superman and Superboy out of the Fortress of Solitude to use the technology in it for his plans. The fortress is so impenetrable that Superman has to call up the Justice League to launch an attack on it.
Armor-Piercing Question: After Superman is done gathering information from Lex Luthor, Luthor gives him something to think about.
Lex Luthor: Why can H'el do much more than you? Is he more powerful than you... or have you just failed to make yourself as powerful as he? And if that is the case... what are you so afraid of Superman?
Batman Gambit: H'el was counting on Superboy to destroy most of the Star Chamber because he was actually destroying the fueling station for his ship and preparing his ship for launch.
Berserk Button: When H'el has Superman on the ropes, he gives him a "Reason You Suck" Speech which ends with him insulting his Earth parents. This gives Superman the strength to get up and fight back.
Bilingual Bonus: The comic covers has a line of Kryptonian under the heading that reads "H EL ON EARTH".
In Superboy #14, H'el telekinetically deconstructs parts of Superboy's body before putting him back together again.
In Superboy #15, H'el damages Superboy so that his DNA unravels, slowly killing him. To save him, Superman puts his Kryptonain battle-suit on him, halting the process, but only temporary.
Broke Your Arm Punching Out Cthulhu: In Superman #17, Supergirl defeats H'el by stabbing him with a kryptonite shard, but holding the shard for so long heavily poisons her. If Superman didn't act fast, she would've died.
The alien hornblower from Superman #1 reappears and is shown to be calling an entity named the Oracle to come to Earth to witness its destruction.
Curbstomp Battle: In Superboy #14, the Teen Titans take on H'el when he attacks Superboy. H'el blows them away with a psychic whirlwind before they lay a finger on him.
Daddy DNA Test: A variation. When Superman puts his battle-suit on Superboy, the family crest should have changed the instant it identified his Kryptonian bloodline. It stayed the same, confirming Superman's suspicions that Superboy's his clone.
Determinator: When H'el tears Superman's battle-suit off Superboy, Superboy keeps himself from falling apart with only his telekinesis and willpower. It takes a great amount of effort just to move, but he still tries to stop H'el despite his condition.
Depending on the Artist: H'el was originally portrayed in promotional art (as well as Superman #13 and Superboy #14) as having a backwards "S" symbol carved on his chest. From Supergirl #14 and onwards, H'el is no longer portrayed with the backwards "S", though this was later revealed to have been due to H'el masking the backwards "S" with his powers, with Kara calling him out on it. Given that H'el was originally a new design for long-time Superman doppleganger Bizarro, the backwards "S" did have a clear purpose, but on H'el it's currently unclear as to how he got it and why he tried to hide it.
Discard and Draw: When Superboy has Superman's battle-suit put on him, it seems to remove his tactile telekinesis, his visceral connection to his surroundings. Instead, the suit alters his telekinesis, increasing his strength and flight while also requiring him to actually touch something to use his telekinesis on it. Once it's off, his telekinesis returns to normal.
The Dragon: Supergirl serves as this to H'el. As long as she doesn't know his plan will destroy Earth, at least.
End of the World as We Know It: H'el must be stopped before he uses his Star Chamber or the energy it drains from the Sun will destroy the solar system. Superman can't stop him in time and he activates it, but he is stopped before he destroys the world.
Exact Words: H'el convinces Supergirl to become his Dragon by claiming that Earth won't suffer after his plan is complete. Superboy later points out that H'el didn't exactly lie: Earth won't suffer when his plan is complete because it will be already dead by then.
Expy: H'el's pale skin and backwards "S" scar was because he was originally meant to be the New 52 incarnation of Bizzaro. However, he was so different that he was made into an entirely different character.
Face-Heel Turn: H'el convinces Supergirl, who just wants to go back to Krypton, to help him resurrect Krypton. However, he never told her that it would also destroy Earth and thus she didn't understand why Superman's opposed to them. Once she learns the truth, she calls him out and sides with Superman again.
False Reassurance: When Supergirl asks H'el if ressurecting Krypton will do anything to Earth, he assures her that the people of Earth won't suffer. That's because they'll all be dead after the Sun implodes if H'el's plan suceeds.
H'el hates Superboy, a human/Kryptonian clone, with every fiber of his body. This is because Krypton used to use clones as servants until they revolted and nearly wrecked their planet.
H'el also thinks Earth and every human on it is inferior to Krypton and Kryptonians. He doesn't care what price Earth has to pay in his goal to ressurect Krypton.
Fire-Forged Friends: When Superboy meets Superman for the first time, he's untrusting of him; only teaming up with Superman because he saved his life. Over time, Superboy warms up to him, impressed by how well he handles situations. He even offers to call in his friends, the Teen Titans to help battle H'el.
Genius Loci: While storming the Fortress of Solitude, Superman and Superboy get sucked into a pocket dimension. Superboy senses it's alive and uses his telekinesis to communicate to it and help them get back to Earth.
Godzilla Threshold: To stop H'el, Superman fears he may have to break his moral code and kill him. However, it's Supergirl that defeats H'el as it is the only way to spare Earth.
I Surrender, Suckers: In Superman #17, Supergirl admits defeat and asks H'el to take her with him into the Star Chamber. However, this turns out to be a ploy to catch H'el off guard and poison him with kryptonite.
Kryptonian Popsicles: The Bottle City of Kandor is a Kryptonian city that was shrunken and locked in stasis many years ago by the Collector of Worlds. It's now located in the Fortress of Solitude. Supergirl finds the place disturbing, especially when she finds her old friend, Tali, frozen in time like the rest of the inhabitants.
Since H'el's a Kryptonian, he's as vulnerable to kryptonite as Superman and Supergirl. Superman planned to use a kryptonite shard he kept in the Fortress of Solitude against H'el, but H'el got to it first and used it to build his Star Chamber
When most of the Star Chamber is destroyed, the kryptonite shard falls out. Supergirl uses it stab H'el and finally defeats him.
Mistaken for an Imposter: Lois Lane mistook Supergirl for a "comely cosplayer" at their first meeting, mostly because she walked into Clark Kent's appartment when Clark and Lois were arguing with each other and romantic jealousy had cropped up.
No-Holds-Barred Beatdown: In Superboy #17, Supergirl pounds Superboy into the ground for trying to stop them from ressurecting Krypton. Having been severely weakened, he doesn't even bother fighting back and instead tries to reason with them.
No Ontological Inertia: When H'el uses his Star Chamber, he directs the temporal portals in it with his psychic powers. When Supergirl mortally wounds him, the portals close, sparing Earth and keeping Krypton dead.
Out-of-Character Moment: In Superman #14. After Superman and H'el are caught in an explosion, Superman comes out of the inferno looking absolutely pissed at Supergirl. He grabs her by the throat, blaming her for everything bad happening and calling her a stupid peroxide brat. He then strangles her unconscious and hangs her by the cape on a lamp post. Why is Superman so angry? Because it wasn't him. It was really H'el disguised as Superman attempting to estrange the two so she would ally with H'el.
Pillar of Light: When H'el activates the Star Chamber and it reaches full power, it emits a giant beam of light that shoots through the sky and out into space.
Punched Across the Room: Happens several times throughout the story. Considering the strength of the characters, they go much farther than a room.
In Superman #13, an undead Kryptonian dragon swats Superman from Metropolis all the way to Ireland.
In Superman #14, Superman punches H'el into a car lot when he tries to kill Superboy.
In Supergirl #17, H'el punches Superman so hard, he's sent flying into space.
Sequel Hook/Trapped in the Past: In Superman #17, H'el falls into a temporal portal after being stabbed by Supergirl. He ends up back on Krypton twelve years before it's destruction, where he is found by a young Jor-El.
Set Right What Once Went Wrong: H'el's plan is to travel back in time to before Krypton exploded, and prevent its destruction. However, the energy needed for the time travel would destroy our entire solar system. Not that H'el cares about our solar system.
Spell My Name with an "S": Is the main antagonist's name H'el or H'El? Promotional materials alternate between the spellings. Since the comics use the traditional all caps font, it is uncertain which spelling is correct.
Storming the Castle: After H'el takes over Superman's Fortress of Solitude, Superman calls in the Justice League to help take it back.
Tailor-Made Prison: Lex Luthor is the only prisoner in a prison that he designed himself. He built the prison when Superman challenged him to create a prison that even he couldn't break out of.
Teleport Interdiction: When the Justice League assaults the Fortress of Solitude, Cyborg tries to save time by teleporting the League to H'el with a boom tube. However, H'el toys with them by redirecting their boom tubes, forcing the League to break in the hard way.
True Companions: On Krypton, H'el was like family to Superman's birth parents, Jor-El and Lara Lor-Van. The day before he was sent into space, they gave him the family crest, making him an honorary member of the House of El.
Unskilled, but Strong: When Wonder Woman fights Supergirl, she remarks that while they are closely matched in strength and speed, she is much more experienced and skilled while Supergirl lashes out with no thought or strategy.
Unwanted Rescue: When the Justice League storms the Fortress of Solitude, The Flash is tasked with finding Supergirl. However Supergirl doesn't want to be rescued because she's on H'el's side.
Villain Teleportation: H'el can teleport himself and others with little effort. When Superboy harms Supergirl in Superman #16, H'el becomes so mad that he teleports the entire Fortress of Solitude miles away.
