Okay, time to explain the hyped planet level statement
First, here is the raw scan of volume 10 where it was stated by Azazel that Regulus Nemea can split the Earth in one swing when mastered. I provided two scans: One is a clean raw scan and the other one is me putting a box around the statement regarding Regulus Nemea.
Red Box is the entire statement from Azazel regarding Regulus Nemea
Blue Box is the "If you master it, you can split the Earth in a single swing" part of the quote
Green Box is the Kanji used for earth

FanTL:
[……It was originally the opponent who the original Hercules faced in one of his twelve labours……. The God from the Bible captured one of them and sealed it inside the Sacred Gear. It became something that was listed as one of the thirteen Longinus. If you master it, you can split the Earth in a single swing, and it can also transform into a huge lion. The "Regulus Nemea"! I remember it also had an ability to protect the possessor from projectile weapons. But I received the information that the possessor has been missing for the past several years. I never thought it would have become the "Pawn" of Bael Team……]
Note on the original raw text that the bolded is the original text for the "If you master it, you can split the Earth in a single swing."
Now let's take a look at the kanji that indicated the supposed "Earth":
ÕñºÕ£░
ÕñºÕ£░ (hiragana is ÒüáÒüäÒüí) could mean ground, earth, solid ground, and vast land.
The kanji for the earth if referring to planet Earth would be Õ£░þÉâ (hiragana would be ÒüíÒüìÒéàÒüå)
Also, here's the video on how to say the name of the planets in japanese
Given the kanji used for earth in the original text, the Earth in the fanTL could be a mistranslation. What's the cause of this? While "split the earth in a single swing" could be a right translation, capitalizing the word "earth" to "Earth" gives a different meaning, which may have resulted in a mistranslation. Smaller case version may refer to ground rather than the planet instead as opposed to capitalized version, which can refer to the planet.
So what Azazel meant by earth here may mean vast land, solid ground, or very earth.
Now into the statement in Hero sub:
Note that while DxD Hero may not be the primary canon of the series, Ishibumi is the writer for this season's adaptation.
To the video itself at around 11:37-11:40 of the video, listen closely to Azazel's statement. Notice how he did not say
chikyuu (
Õ£░þÉâ (hiragana would be ÒüíÒüìÒéàÒüå)) but instead he says
daichi (
ÕñºÕ£░ (hiragana is ÒüáÒüäÒüí)) instead. Given how the original text and what's said in the japanese for the adaptation aligned, Azazel may not meant planet Earth to begin with when he said earth.
What made me look into this?
Even for just the hype statements alone, notice how Azazel's statement seems to be an outlier given the current fanTL compared to other hype statements. let's look at them.
Kokabiel is stated that he can destroy a region (Volume 3 Life 4)
"This is to keep it to the minimum. To tell you the truth, if Kokabiel were to fight seriously, not only this academy, but the whole region would be annihilated. Adding to that, he has already gotten ready for that. My servant has seen him releasing his power at the school grounds."
Serafall is stated that she can destroy Japan (Volume 4 Life 2)
"Onee-sama, Please be prudent. If my onee-sama, the Maou glitters, then this small country would be destroyed many times over."
Dimension Lost is stated that it can transfer an entire country and its people into the dimensional gap to be destroyed (Volume 9 Life 3)
"Annihilation Maker is the same. It can create countless demonic beasts. For example, those massive fire breathing monsters over 100m tall you see in movies can be recreated by sheer will. The ability to create monsters from imagination. Isn't that a disaster? This ability, depending on the user's capability, can create on the scale of hundreds or even thousands. Like Dimension Lost, this is one of the worst bugs in the Sacred Gear system. Dimension Lost is also extremely dangerous depending on the user. Once the mist reaches the scale of countries, it can transfer an entire country and its people into the dimensional gap to be destroyed."
Absolute Demise is stated that it could lock an entire small country within a crystal of ice (Volume 21 Life Lucifer)
—[Absolute Demise], one of the Longinus. It was also an independent avatar type. Once activated, the Ice Princess would appear at the wielder's side. The Princess would obey the commands of its wielder, and freeze anything. As long as Lavinia wanted to, it could instantly turn the entire area into a frozen world. At its maximum range, it could lock an entire small country within a crystal of ice.
Azi Dahaka is stated that he can destroy all of Europe (Volume 21 Life Lucifer)
It was certain that he was manipulating Trihexa alongside Apophis, but Aŝi Dahāka by himself certainly had the strength to destroy all of Europe.
Now look how many country level statements there is while there's a small continent level statement for a Heavenly Dragon Class being. Given the hype statements, misTLed Azazel's statement seems off compared to these hype statements but if the word "earth" was properly translated, Azazel's statement would be consistent to the hype statements above.
And country level would seem more consistent if we consider using the values of how powerful Issei's unboosted Dragon Shot is when using vaporization value or multiplying the value that's calculated when using pulverization value by using the consistent 12-14 Boost (not saying that we should use the multiplier and make another CR but I'm making a point that country level seems more possible than planet level at the moment)
In Conclusion
Planet level hype wasn't even there originally given what Azazel mean by earth could be vague.
