Anticlimax Boss: Not that Shu Shirakawa is easier than the mooks, but after fighting someone like Dark Brain, he's much easier, even when he's the True Final Boss for Original Generation Gaiden. Quite a shame when he was horrendously difficult in Super Robot Wars 3 and was the hardest boss in SRW history in his Super Robot Wars Alpha Gaiden incarnation, though probably the primitiveness of the game engines for those games contributed to his difficulty back then, as well as his knack of constantly casting Spirit Commands like his Alpha Gaiden counterpart.
In the Second Original Generation, Euzeth Gozzo is a lot easier, especially after pitting you through Perfectio and his cronies.
Badass Decay: While Lamia Loveless' treatment in Original Generation Gaiden is debatable (be it this or mere Badass in Distress), The Inspectors turned her Angelg into nothing but a "Humongous Mecha that flies and constantly gets beaten up and only good for blowing up" (except that one time performing Phantom Phoenix with Royal Heartbreaker), making Lamia LOOK like a Faux Action Girl, until she gets her hands on the Vysaga, and only started racking up good kill counts afterwards (while they made a black-painted Angelg for Echidna Iisaki and...well it only serves to get shot down, too). The Record of ATX manga portion of The Inspectors (which is based more on the anime while taking up some story elements from the game) averts this, making Lamia using the Angelg just as capable enough of racking up kill counts.
In terms of gameplay, while the Leige Geios from Super Robot Wars 4 is still formidable in the Second Original Generation, it's nowhere near the monstrosity it was when it first appeared in the Classic Timeline. This may be a case of being a Degraded Boss later in the game.
Complacent Gaming Syndrome: For the custom MK II Gespensts in the Second Original Generation, most players will usually stick with the Type-N frame as its weapons have longer range and its final attack is ALL-based, meaning it targets both units in a "Twin Unit" and any adjacent Twin. Expect pilots using this mecha to be near the top of the kill count, especially if they're paired with another pilot for a Twin Unit with the "Violent Assault"note Gain the effects of the "Accelerate" (+3 to movement), "Fury" (the next attack bypasses enemy barriers and defensive pilot skills), and "Assail" (any non-MAP attack can be used post-movement) Spirit Commands or "Continuous Attack"note If the next attack destroys an enemy or both enemies in a Twin Unit, pilot gains an extra action on the same turn "Twin Command". Bonus points if both pilots have the "Continuous Action"note If the next attack destroys an enemy or both enemies in a Twin Unit, pilot gains an extra action on the same turn. This only works once per turn pilot skill.
Crowning Moment of Heartwarming: In the first game, during Ryusei's route, after being told that the SRX (the result of combining the R-1, R-2, and R-3) can no longer be formed (which they had just did some time prior to the conversation to win a battle), Ryusei says something along the lines of "The real 'transformation' is all of us", meaning all his companions. That certainly means a lot for a robot otaku.
Axel/Kyosuke is lent a bit of weight by the fact that some of the dialog when the two fight each other implies that Kyosuke's counterpart from Axel's home universe is gay.
Not really: the implication is because Beowulf doesn't have a female companion, since Excellen doesn't exist there. Beowulf obviously isn't going to have much in the way of friends. This is simply Yaoi Fangirl interpretations running wild.
Axel/Lamia is less of a Crack Pairing now: Original Generation Gaiden threw a short, but meaningful conversation between the two of them that could be interpreted as Ship Tease, plus Axel saving Lamia and claiming that he accepts her as a person.
Goddamned Bats: Every Original Generation game has at least one example, though Barrelions are the most consistent, having too much HP, will occasionally defend when attacked and come in large numbers. They don't exactly pose a threat, but are typically annoying during scenarios they appear in. At one point in Original Generation 2, the game uses this to create a literal Beef Gate made of Barrelions forming a wall.
The mass-produced JinRai in the Second Original Generation has a boatload of HP and armor in the same ballpark as the Barrelions, but higher, with an unusually strong mobility rate. Justified since they're an offshoot of the actual JinRai, though they're made more annoying with each one having the same "Afterimage" ability note Gain a 50% chance of evading any attack at 130 Will or higher as the JinRai. Unless you cast the "Strike" Spirit Command note Gain 100% accuracy for one turn for a guaranteed hit, you'll likely be burning away pilots' Spirit Points you were intending to save for dealing with bosses later in the same scenario. Oh, and mass-produced JinRai come in hordes of at least a dozen at once.
Wilhem von Juergen crosses it when he shoots a defenseless Lamia and makes the team think he killed her. It's more than agreed that by that point, any sympathy he might have had in the OVA's lost and after his demise, he'll forever be cemented as an unsympathetic Big Bad Wannabe. Though strangely, he's posthumously pulled away from the Horizon when they introduced Kaoru Tomine, who turns out to be really remorseless in terms of villainy and even used Juergen's previous designs to fuel his diabolical brainwashing system, basically cementing that compared to Kaoru's remorseless sociopathic tendencies, Juergen would look like a saint and very much a legit Anti-Villain...
Nightmare Fuel: Jun Kanan sending the TouTetsuOh to kill off and devour some allied NPC pilots. Would look normal, if not for the narrative to shift to a first-person perspective of one of the NPCs trembling as the TouTetsuOh looms over them, only to suddenly vanish, reappear with its jaws open and fade to black, all in the while hearing nasty crunching sounds and the game text about the pilot screaming to death.
Player Punch: All five units of the Huckebein series are outright annihiliated by newcomer Amara in the Second Original Generation. Doubles as a Tear Jerker for some veteran players. Made worse if players believe the rumour that Namco Bandai and Sunrise are indeed responsible of getting rid the machines just because they look like Gundams.
Up until Original Generation Gaiden was released, Lamia getting shot down dead by Juergen, making it look like Death by Adaptation, was rather convincing enough to punch you in the gut with the prospect of Lamia, one with all original plot threads resolved, being Killed Off for Real to leave some space. Thankfully, averted/softened once Original Generation Gaiden was released.
Scrappy Mechanic: Zigzagged with the "Twin Battle" system. Unlike the squad-mechanics in the Alpha games and Super Robot Wars Z, a Twin Unit can only be formed during scenarios rather than before in the intermission menu. Furthermore, the system requires pilots to reach 110 Will first before players can form a Twin Unit, making this unlikely at the start of scenarios (since all pilots start at 100 Will) except for characters having reached "Ace" status AND are part of the top three Aces on the roster, which will grant them the required 110. The problem still persists because that only applies to at least three characters on the rosternote More are possible through Will-raising Spirit Commands or through appropriate equippable parts given to units which grants their pilots higher starting Will at the beginning of scenarios, while Will gains vary between characters. Finally, the Twin Command can only be accessed from a Twin Unit, and requires Spirit Points from both pilots to activate, though the Command's effects apply to the Twin Unit, with some Twin Commands being better than others (for example, "Soul"note Deal 2.5 times the damage for the next attack).
Come the Second Original Generation, the Will prerequisite is gone, and players can form twins in the intermission menu. Unfortunately, so are Twin Commands.
Despite Sanger being one of the top characters in the Second Original Generation, players can't seem to figure out what benefits his Ace Bonus providesnote When Sanger reaches 130 Will, auto-cast the "Fury" Spirit Command because of the following reasons:
Players normally cast "Fury" when they want to apply debuffs to enemies using specific weapons that deal debuffs (most enemy barriers/defenses can negate these attacks), and all three mecha that Sanger can pilot in this game (Dygenguard, Grungust Custom, and Grungust Type-0) do not carry the "Armor Breaker" equippable weapon to deal the debuffnote Decrease enemy armor by 10%, which makes having "Fury" pointless.
"Fury" would likely be used half the time in conjunction with the new "Maximum Break" mechanic, which also ignores barriers/defenses by default, except it isn't possible for Sanger to trigger it.
The AM Gunner in the Second Original Generation is a unit no player wants to use as its arsenal needs a pilot who has the pilot skill "Hit & Away"note Enables movement after attacking, weak attacks that can't be used post-movement, and no Huckebein MK III to dock with to form the Huckebein Gunner, since all Huckebeins are destroyed in a mandatory event.
It's implied the Machine Cells stopped functioning after the Earth Cradle collapsed, particularly since the supercomputer Magus Gebo that powers the Machine Cells has also been destroyed in the collapse.
Win the Crowd: To say the announcement that Namco Bandai will personally translate the Sony PlayStation 4 version of The Moon Dwellers into English being a good thing is an Understatement - the publisher is being universally praised for it.
Ensemble Darkhorse: Latooni's perhaps the most well-received character (who isn't Ratsel) and didn't appear in prior SRWs (although she was loosely hinted at in Super Robot Wars Alpha 2). A fair bit of the plot in the first two games involves her backstory.
Nightmare Fuel: Snarking aside, let's just say if you're not Lamia, you WILL never want to get absorbed by them and turned into goo.
The Scrappy: Second by a far margin, with Lee as one of the biggest scrappies in SRW. With Lee possibly getting Rescued from the Scrappy Heap, Juergen and the ODE System could take the throne, but as far as SRW goes, he still has to compete with Mist Rex.
You Keep Using That Word: Beowulf's MK III is NOT the Alt Eisen Nacht, which appears in Endless Frontier and coincidentally in the prologue scenarios of Original Generations, where Excellen coins Kyosuke's Alt Eisen with the "Nacht" monniker after he paints it temporarily blue in hopes to fool Divine Crusader Remnants. This is because The Federation in the Shadow-Mirror universe approved of the MK III's specs, rendering it as the next-generation machine.
Also, the Nacht in Endless Frontier sports an additional mini-claymore launcher, something the MK III and Alt Eisen don't have.
It actually is called the Alt Eisen Nacht. The prologue scenario naming and the Endless Frontier versions are both named after it, with the former being a Mythology Gag. This is known from Original Generation 2 where the Alt Eisen Nacht is a Dummied Out unit, implying they originally intended to have the fight between Axel and Beowulf be playable, but decided against it.
Draco in Leather Pants: Destroyed the entire Huckebein line, shot down Ing twice in a surprise attack, and is very fanatical of her boss Euzeth. Fan reaction to all this? "It's not her fault! Banpresto had their hands forced by Namco Bandai!". Granted, those acts are very far from Moral Event Horizon (compared to, say, Lee and his killing of Daitetsu) and ever since The Inspectors, they have been shuffling out the Huckebein series, so the reactions might look justified. Also look at Evil Is Sexy right below.
