The third series is set in a universe where the battlecruiser Centurian was late at the Battle of OrionThe Evronians of the original series are a powerful empire that has been virtually undefeated until Xadhoom started hunting them down, while the ones of the reboot are somewhat technologically inferior, fragmented due to a recent civil war and deadlocked in a war with the less numerous but technologically more advanced Guardians of the Galaxy. How it happened? Putting together pieces from both continuities it's possible to find the point of departure. The reboot series mentions there had been a moment where the Guardians had almost been annihilated, and only the merciless Guardian Drones managed to stop them. The original series mentions that the battlecruiser Centurian (once the best warship of the Imperial Fleet, but now only a well-armed but antiquated piece of space junk) arrived at the Battle of Orion at just the right moment, saving the day for Evron. Maybe Orion is the Evronian name for Clonius, where the Guardian Drones had been created, and an Evronian defeat there allowed the Guardians to unleash the warriors that halted the Evronian Empire, even succeeding in destroying the Imperial Palace and burning down millions of Evronian Spores at once, weakening the Empire enough to allow the Guardians to continue opposing it and causing a civil war at the death of a more recent Emperor.
Xadhoom has an Healing FactorShe's shown to have Matter/Energy manipulation powers and shapeshifting. Both of those should allow a Healing Factor to some degree. As for how she would regrow them... Replacements made of the flame-like substance that occasionally appears around her isn't completely implausible. Something supporting this is the fact that, in flight, her lower body occasionally turns into flame and back.
Everett Ducklair in PK2Everett didn't escape from Earth to avoid the impending invasion, he escaped to lead it.
The Evron "Sage Among Us"He isn't a one-shot character intended to give the Evrons a way to return, but is in fact Gorthan. In PKNA #20 he lost his energy tank, which was reused by a technician to power his robot Mekkano. Said robot proceeded to integrate various components into himself, going into a frenzy at the sight of Gorthan's crashed spaceship. When Gorthan recovered the tank, the robot integrated him, took off into space and was recovered by a Evron ship, with Gorthan still inside. It is possible that the Sage is a "reincarnation" of Gorthan?
This series's Organization and the Double Duck version are the same group.It explains why they're so determined to rid themselves of Donald: they know exactly what he is, or will be capable of.
Xadhoom isn't Dead.She's still alive, inside the sun, sustaining it. After all, it was never explicitly stated, that she had died. This also explains why the back-up withdrew into the disc: that version of Xadhoom knows the original's still alive.
Super Duck and Astrongman existed in both continuities, and Lyo was the latterAstrongman is shown in a few flashbacks, and is a Badass Normal Gadgeteer Genius with a great resemblance to Lyo, while Super Duck is a Flying Brick. It's possible that, after Super Duck's death's in combat due his Kryptonite Factor, Lyo avenged him and took over as the city superhero.
Xadhoom isn't an Alternate Company Equivalent of Superman...She's one of Alucard. Evidence: Both originally had four-letter names. (Xado/Vlad) Both set out to achieve a grand and noble goal, and lost everything because of it. (Xerba/New Jerusalem) Both are composed of a shapeless amorphous substance, and merely assume arguably humanoid forms. (Gaseous substance/Blood-shadow) Both were transformed, granted near-limitless power, and adopted seven-letter names. (Xadhoom/Alucard) Both are capable of shapeshifting at will. Both are generally acknowledged to be damn near invincible.
In the 2013 relaunch, there'll be a offhand reference to Xadhoom having been inducted into the Red Lantern Corps, or an Expy of themShe's perfect Red Lantern material, and given her lack of functional blood, it'll be relatively safe for her to remove it. Although, given her own powers, if so, we may well be looking at the equivalent of a Emotional Entity/Ring-Wielder hybrid, who's driven by pure hatred. To give an example, the last time that happened, was Kyle Rayner's first stint as Ion.
After the end of Pikappa, Donald will become the classic PaperinikIn the last issue of the rebooted series, the series itself never happened, with such changes to the timeline that the Guardians never existed and the Evronians became peaceful. However, the day was saved thanks to a last apparition of Donald as PK, who managed to record a message to himself before the original timeline ceased existing. While the Duckburg of the new timeline is safe from alien threats, it is not from local supervillains. Inspired by the mysterious alter ego he saw, Donald will be prompted to create a costumed identity for himself.
All the series have taken place in a single universeThe universe of PK may be similar to The DCU: every few years, some event causes profound changes to the timeline, sometimes rewriting history completely. After all, time travel is routine in PK's 23rd century, and some stories explored the implications of causing changes in history; in one issue, Paperinik and the Raider stopped an experiment that would have initiated the total destruction of time - but maybe it would have just "rebooted" the universe. And Everett toyed with the timeline at the end of the original series, bringing Lyla back to our time, changing the ending of #43. Who knows how many times things like these may have already happened? So, some time after the end of PK2, someone or something changed the dawn of history and created the Pikappa timeline. After all, at the end of those series the timeline was profoundly changed.
In the What If? version of PKNA #33, Lyla lied to Paperinik about the fate of Duckburg's inhabitantsThe Othership was simply lost, Lyla never activated it, and Duckburg's populations (even if there's no mention of them, Donald's relatives were probably involved too) really died. The grief prompted PK to a Face-Heel Turn; over time the Raider, Anti-Villain as he is, felt sorry for him, so he contacted Lyla and they came up with a plan and a made-up story to make PK redeem himself and give him at least some consolation. Unfortunately, neither Lyla nor the Raider could predict that Kronin would shoot Lyla. Whatever the result, however, doesn't change the sad truth that Donald/PK is the last Duckburgian left.
What may happen to Everett between the end of PK2 and the distant future of PKNA #48He has decided to return to Corona and let his daughters decide for their destiny. Considering how his wife won't be the least happy to see him, he'll probably go into hiding, but will begin fighting for a change of his strict society which, by the time he took Juniper and Korinna away, was starting to take a really bad direction, with the risk of the matriarchal government becoming a dictatorship of emotionally stunted women. Either he will manage a pacific change, or a civil war will erupt in Corona; much will depend on what choices Juniper and Corinna will make. Either way, Corona will finally change into a more just society. At that point, a tired Everett will decide to return to Earth, at Dhasam-Bul; forgiven by the old prior, he'll eventually take his place, until the day he'll go help One in his quest to become a complete individual.
In the PKNA universe, Odin Eidolon exists no matter what happens to the timelineIn #34, the Gryphon caused so many changes to history that he created a Bad Future where Ducklair Tower was even destroyed. This should have meant no more One and so no Odin Eidolon in the future. However, the Gryphon had taken One and the Organization used him to create... Odin Eidolon, who raised in their ranks and then underwent a Face-Heel Turn that prompted him to an action that, ultimately, resulted in the correction of the timeline. In the What If? story of #49-50, he was probably the mysteryous individual who ordered the Time Police to free PK; when Duckburg was destroyed by the Cold Sun experiment, he managed to distribute his data around systems outside the city in the nick of time, using the same trick Two employed to survive erasure. It took many years before he finally reassembled himself and regained self-conscience, but he would still become Odin and help his friend. It seems that you can tamper with time as much as you want, but history needs Odin Eidolon, so he will always be there.
One and Two weren't intended as Everett's greatest creationsThey were intended as AI companions to Juniper and Korinna respectively. Even the duck himself realized how callous the plan of virtually kidnapping them was, and created One and Two to aid them in adjusting to Earth society.
Grrodon in the 23rd century isn't really the last EvronianHe's rather the last of the Evronians who wanted to restore the original Empire. After the fall of Evron in PKNA #37, chaos erupted among the surviving Evronians, probably splintering into factions. While some wanted to return to their former glory, others gathered around the mysterious "sage" whom we saw only a glimpse of in the series: Gorthan, now fused with Mekkano. After his experience on Earth, he reflected on what the status of Evronians would be after the dissolution of the Empire: a decayed race, rightfully hated by everyone in the universe because of their past conquests and exterminations. A change was needed, but obviously it couldn't be achieved quickly, so Gorthan decided that a self-imposed exile was needed. When we see Grrodon's sad end, it's just the end of the attempts to rebuild the old Evron; somewhere else in the universe, a new and better Evron is being built under the benevolent rule of Gorthan, waiting for the day they'll be ready to go back and be accepted...
Geena the journalist from PK2 was originally planned to have a bigger roleIn the scene where she's first seen, Paperinik misses the first Channel 00 news hosted by her by a few seconds, with the panel centering on her as she introduces herself to the public. All this made her look like she was going to be important in future issues; instead, she got only a few unimportant appearances. Given she's got the same name as the 5Y droid from PKNA #5 and #12, she may have had some link with her, but given how PK2 was cut short, the writers never managed to use her as intended.
Nebula Faraday is either dead or imprisoned in an Evronian jail or labShe was never seen again after PKNA #7, and at the end of that issue she was lost among the mountains of New Zealand. Since she was quite out there with her head, the possibility that she just died from hypothermia there cannot be ruled out. However, since she was so fanatical about the coming of aliens, she may have met an Evronians patrol some time later and let herself be captured by them. The Evronian scientists would have been very interested in an earthling that expressed feelings of joy towards them, so they sent her to one of their research center, to be subjected to experiments similar to the ones they wanted to do on Angus Fangus. The results, however, were not satisfactory, so Nebula is currently languishing somewhere in the universe, possibly forgotten after the fall of planet Evron. E Ither this, or there's a dormant army of Nebula/Evronian hybrids somewhere...
At some point, Grrodon's true identity was discovered by the US ArmySome time after he was arrested as McCoy, his true nature of Evronian shapeshifter was discovered and he was transferred to some research center, where he was experimented on and interrogated (probably also in unorthodox ways). He never gave up and, months later, the same ability let him escape but the experience left him so broken that, for some time, he even renounced his mission and just tried to blend with earthlings. The friendly truck driver who gives a ride to Korinna in PK2 #12 looks a lot like McCoy, just with thicker hair and beard: it was probably Grrodon.
In both continuities, Duckburg's old superhero community was torn apart by some tragedyIn PK2 and especially Pikappa, Lyo's memories and flashbacks show that, a few decades earlier, Duckburg lived sort of a Golden Age of superheroism (Pikappa shows there was even a Justice League equivalent in the city). However, at some point the stakes became higher; some hero or villain was killed by the opponent, maybe even just involuntarily, and that caused an escalation that plunged Duckburg in a sudden dark age. (Vulnus Vendor probably had a role in all of it - his first appearance showed how dangerous he could be even from prison - but it was never proved, so Lyo is very bitter about it.) Most heroes and villains couldn't cope with it and they left the city, or just quit their careers; the rest was driven away by the administration and angry citizens. Soon after, Scrooge McDuck settled permanently in Duckburg, making way for the city's recovery. Today, older Duckburgians do not talk gladly of those days and the younger do not know of them at all. The first appearances of Paperinik were greeted with tension: since he originally was an avenger, the citizens feared a return to the darker days, but over time he has stayed has the only constantly active superhero in Duckburg, so no fear for history repeating itself... for now.
Xadhoom's powers were amped up way beyond their normal states for the majority of the seriesThe cause? Her absorption of the energies of the Xerbian sun. If they were released, she would be much weaker, but much more stable and less susceptible to her powers killing her.
