History YMMV / ShinMegamiTenseiLiberationDx2

*** All Berserk demons, but ''especially'' Berserker Guts and Griffith as of April 2023, having received their own fourth panels and received much-needed boosts to their unique skills to make them properly competitive again. Skull Knight's allows him to spam his Sword of Actuation, Guts now adds another attack every time an enemy gets downed and gets multiple uses of The Struggler, Berserker Guts gets a tremedous 50% Phys damage boost, Griffith now can boost his party with Zenith, spam Charm and gets infinitely faster, Zodd can now spam Rip and regenerate like nobody's business...

** '''''Demeter.''''' She's by far the worst of them all to the point [[UpToEleven people want her nerfed]], her Elusis' Blessing gives her Null mortal, a bulwark at the start of her turn equivalent of 1500 HP to all the party alongside Luster Candy, and while everyone is on bulwark they ''will'' null all ailments, earn 2 MP, and receive -20% less damage of ''everything'' and if anyone gets hit with any attack, let it be physical, magic, and even fractional, she'll give everyone ''another bulwark equivalent of 25% of everyone's HP each time you hit anyone alongside Luster Candy'', and it will keep going until she dies, not even [[FromBadToWorse Elohim]] can outdamage her bulwarks, there's also the fact her skill "My harvest!" also grants a bulwark of 20% HP, her Second panel does that as well alongside defensive cry,making any party where she is in escencially unkillable due the amount of stuff she does. (and unlike Erlkonig, there's no counter to this.)

** Following the return of Elohim, Shaddai and Sabaoth were quickly revealed one after the other, thus making this the Godly Trio's second appearance overall and first playable appearance ever since their debut in {{VideoGame/ShinMegamiTenseiII}}.

** Angra Mainyu. His 16 Scourges is an [=AoE=] fractional attack, a.k.a. [[UnblockableAttack completely unstoppable]], which can slap every ailment in the game, moreso if he's paired with a paneled Mother Harlot or Samael to remove those pesky barriers before he acts. His unique Everything Evil gives him 2 MP at the start of his turn, and when combined with proper setup, this allows him to fire off his expensive 16 Scourges on the first turn ''even when going first [[UpToEleven against Undead Alice or Adramelech]]'' (though not both), so unless you have Mahamayuri, you really can ''not'' allow him to act. Lastly, he has three innate repels that makes him a very attractive ally for Demiurge or Atavaka, as well as innate evasion of up to 30%, making him a potential nightmare for physical attackers.

** Psychic Erlkonig. This guy is considered one of the most annoying things in PvP defenses due how ''hard'' it is to kill him. His passive skill ''Alder King'' [[BoringButPractical is simple]]: at the start of his turn it heals his party by 15%, while at the start of each enemy turn, it casts Tarunda (and if it's fully paneled, it will also cast Rakukaja) and makes it tremendously hard for ailments to stick to him. It doesn't sound bad until you find that if boosted and paneled, it will heal more than [[UpToEleven 1000 HP]] for all the party members (with even more of himself, given his Power of Life passive grants him a 3-turn Lydia), and thanks to its high VIT defense, he will be alive to keep everyone else perfectly fine. And with Null Mortal, [[ShootTheMedicFirst killing him first]] is out of the question. Now pair this demon Beelzebub (97) and you got an unkillable party that will constantly heal until Death Flyers kills you.

* UncannyValley: Hollows in Aura Gate 2 are spirits that have slowly begun to develop humanity, but are still fundamentally incomplete. They are easily swayed and have... ''issues'' communicating. For instance, a Hollow woman asks you to find her child in a dangerous area. When they meet, it's a joyful reunion... only to be revealed they're ''not'' mother and child - you can find their real relatives dead nearby, and they have no idea the other is not who they believe is.

** Astaroth is an insanely fast physical attacker whose main attack, Lord Astaroth, can easily destroy a single enemy, and if it connects, it will proc a second attack. Enemies killed by either attack will be forbidden from reviving, allowing him to seal up to two enemies while dealing a Critical hit (preserving his turn), ''increasing his team's Attack and Accuracy/Evasion by 20% and lowering the enemy's by the same amount'', and allowing his passive, Master of Hell, to ''give his team another turn'', which can make all the difference in a game based on Intimidating Stance and Cerberus A and Masakado A's turn manipulation.

*** Huang Di's sword form is a terror in Battle Tower, mainly due to the BT mechanic giving the MC 90% damage reduction at the start of a battle, allowing them to survive any initial onslaught even when going second before retaliating with the sword's Yinglong Flash, a powerful [=AoE=] Phys pierce attack with massive critical rate, especially when combined with Huang Di's shield that gives further accuracy and critical bonus, or Yoshitsune shield which gives the MC 5 mana after every kill, allowing them to spam Yinglong Flash even more.

** Arioch. On top having ''obscene'' HP, he gives himself the unique Bulwark at the start of battle which gives him additional 3,000 HP, ''and'' a one turn Null Mortal in case you want to snipe him ASAP. Once you fail to kill him, he will give himself charge ''and'' might, then unloads his Lionfall on your team, which all but guarantees a TotalPartyKill. While he doesn't start with ailment immunity, his Protector self comes with the transferable skill Null Bind/Weak, so you can bet he ''will'' be immune to those. If you see him with ''any'' of the above recent game breakers, '''''good luck'''''.

** Psychic Erlkonig. This guy is considered one of the most annoying things in PvP defenses due how ''hard'' it is to kill him. His passive skill ''Alder King'' [[BoringButPractical is simple]]: at the start of his turn it heals his party by 15%, while at the start of each enemy turn, it casts Tarunda (and if it's fully paneled, it will also cast Rakukaja). It doesn't sound bad until you find that if boosted and paneled, it will heal more than [[UpToEleven 1000 HP]] for all the party members (with even more of himself, given his Power of Life passive grants him a 3-turn Lydia), and thanks to its high VIT defense, he will be alive to keep everyone else perfectly fine. And with Null Mortal, [[ShootTheMedicFirst killing him first]] is out of the question. Now pair this demon Beelzebub (97) and you got an unkillable party that will constantly heal until Death Flyers kills you.

** Maria's Miracle of Fatima procs every single time an ally is downed. First, it removes revival block, making it impossible to put anyone on the ground for good as long as she's alive, plus a 1-turn Luster Candy and some healing - and it still procs when ''she'' gets killed, which means she cannot be permanently killed, ever. She has obscene HP (both from her high base HP and the many innate HP bonuses she has), is immune to ailments, Nulls Mortal, is designed to easily spam Salvation, increases her team's natural MP generation by 1 just by being there, and once paneled will cast a 1-turn Tarunda + Rakukaja during opponent's turn to further neuter their offense (especially when paired with a paneled Erlkonig, who does the exact same thing). To cap it all off, Miracle of Fatima will ''revive everyone on her side at full HP'' at the end of the enemy turn if there's a single dead ally. Even if ItOnlyWorksOnce, it's still enough to break any kind of enemy team.

* ThatOneSidequest: The Tokyo Abyss dungeon. For starters, you can't use your demons there, only the Armament you've created, and you start with a single Common demon of 1 or 2 ★, and three demon slots. Your objective is to traverse over 60 levels of pure random horror, from allies and fusion results to extra moves. Nobody can use Brands, and healing and revival are restricted to Founts of Healing and moves - no LevelUpFillUp for you. You can't switch the Shield you start with in battle, only the Sword. Your MC caps at lv 50 and your demons cap lv 99, while enemies go well beyond lv 100. ''Every single battle'' opens with a checkpoint - if you bite it or quit, you return to the exact state you were before entering it, and you can only traverse each level in a single line, denying you any goodies that may lie in other paths or giving you the chance to refresh a bit before the level boss. Welcome to hell.

Welcome to hell. The 2022 update eases some of the horrors; enemies now gain slightly fewer levels per floor (but they still have no level cap), and your demons (but not your MC) can finally go beyond level 50.
