In this RWBY story by Paulxion, the story starts during the finale of Volume 3 specifically around episode 9 the Fall of Beacon and Vale went from bad to worse. Simply put, during the prologue implies that Penny was hacked and destroying Atlas, Mistral, and Vacuo airships, Team RWBY went missing, the White Fang, hacked androids, and Grimm besieged all of Vale, and the Huntsman of Beacon were down to their last few survivors. Jaune, in the thick of the battle, was saved from death by Raven. Using her powers, she sliced a rift in time and entrusted Jaune with the task of changing the past and protect her daughters Yang and Ruby so the loop doesn't happen again. Jaune suddenly wakes up on the floor of an airship just in time for his first day at Beacon Academy...
The story then becomes example of a subverted Peggy Sue: despite Jaune returning from an apocalyptic future, he doesn't have any of the future memories associated to similar works. Instead, Jaune is still like his canon counterpart with only a couple but significant differences: substantial amounts of aura, above average combat skill, and Black Dust. As a result, Jaune and the rest of the RWBY cast start to take a more proactive response/approach towards old/canon and new events and relationships established by the canon, leading to many deviations especially leading up to canon Volume 3 finale that fundamentally changes the post-Volume 3 setting.
RWBY: Tomorrow and Never Again contains examples of:
- 0% Approval Rating: Cinder used altered footage of Jaune and Ruby "murdering" General Ironwood and make them look responsible for the Fall of Beacon and Vale. Naturally, the Vale Council decided to use Jaune as a scapegoat to redirect the focus of its citizen's, and by extension the world's, hatred towards him. Currently, their bounty is 5 million lien. EACH.
- 100% Adoration Rating: In the story Jaune is beloved by his teammates, friends, and mentors after they witness his courage and strength that he exhibits and are all willing to follow his orders after leading them though missions that would destroy most veteran hunters. In the larger context of the story, after Jaune and his friends stopped the White Fang, "killed" Adam, and saved Vale, they were regaled as Heroes and were awarded the Heart of Courage by General Ironwood himself.
- Ace Pilot: Ren and, to a degree, Neptune, are prime examples of this, both being able to fly a Bullhead into Mountain Glenn and crash it an Ursa Major that took down a building, maneuvering a Vytal air transport through flocks of Nevermore, and escaping the city of Atlas in the Big Flying Whale with the entirety of the Atlesian fleet coming right after them.
- Adaptational Badass: In the canon timeline, Jaune was barely able to pass as a huntsman in training due to his sub-par skills with his weapon, Crocea Mors, and high aura count. As a result, he often left the fighting to his friends till Post-Vol.3, where he matured and joined the fray. Here, Jaune is a very competent Huntsman, with Jaune's teachers Oobleck, Port, Ozpin, Ironwood, and Glynda (reluctantly) acknowledging that Jaune is a prodigy. His Leadership, Aura Levels, Semblance, and skills have all increased, and his arsenal is expanded with the inclusion of Ironwoods Hand Cannon and Wilt and Blush.
- Adaptational Heroism: In canon, Raven is a Social Darwinist who is firmly against involving herself in Ozpin's Secret War. Here, she is unambiguously heroic, and the reason Jaune was able to back in time in the first place.
- Adapted Out: Since Ozpin survives the Fall of Beacon this time around, Oscar Pine doesn't become his next host, leaving him out of the story.
- All Your Base Are Belong to Us: Like in canon, Beacon and Vale are attacked and decimated. As of chapter 75, Atlas-Mantle is under siege by their new hijacked Warship: New Beacon.
- Ancestral Weapon: Jaune wields Crocea Mors as per canon. However, it is revealed that Crocea Mors was not used by Jaune's forefathers for heroic pursuits, rather it was used to massacre their enemies, Faunus in particular, during the Faunus Rebellion and the Great War. The Arc family were implied to be responsible for why Menagerie is currently two-thirds desert due to "salting" the island during the rebellion.
- Badass Crew: At first it was Team JNPR and RWBY. Currently you have Team JNPR, RWBY, CFVY, SSSN, BRNZ, NDGO, ABRN, Qrow, Glynda, Port, Oobleck, Ciel, Penny, and Amber all on one mobile airship base.
- Band of Brothers: All the adventures, missions, and situations that are thrust on our Badass Crew causes them to rely and trust each to undertake some of the most impossible circumstances and surpass them.
- Bombers on the Screen: Atlas makes use of their advance technology including tactical hologram boards.
- Chick Magnet: Jaune is this in spades. Though not a shipping fic, Jaune has gained the interests, friendships, and affections of a majority of the female RWBY cast. Including Ruby, Weiss, Blake, Yang, Pyrrha, Velvet, Coco, Nebula, Gwen, Dew, Octavia, Penny, Reese, Arslan, May, Amber, Neon, and Sienna.
- Death by Adaptation: Ironwood is granted a Mercy Kill by Jaune so he isn't completely taken over by the parasite Grimm.
- Everyone Can See It:
- CFY to Velvet, Yang to Ruby, Weiss, and Blake, Nora and Ren to Pyrrha, and DGO to Nebula in regards to their feelings for Jaune.
- Ozpin to Glynda in regards to her past relationship with Ironwood.
- For Want of a Nail: Due to the nature of the story, Jaune has more of a prominent role in the RWBY universe, and has profound impacts on events.
- Due to his above average skill, Jaune was tested by Glynda to make sure that his transcript were in order. During a combat simulation he has a Heroic BSoD and remember the Fall, causing him to turn berserk on the holo-grimm, passing the test and cementing his place at Beacon. Consequently, the Cardin blackmail plotline doesn't happen and Jaune doesn't train at night with Pyrrha.
- Instead of Professor Port comforting Weiss on Team RWBY's leadership Jaune step in and manage to make Weiss realize her own folly and returning her pendant thus cementing their friendship and Weiss's affection.
- Jaunes presence at the docks with Blake and Sun, and his saving of Blake, causes Blake to fall for Jaune rather than Sun.
- Jaunes friendship with Velvet leads the two to try and visit Tuksons for some books, only to come across the sight of his murder.
- The second battle of Mt. Glenn results in Jaune dismembering Adam and claiming Wilt and Blush himself. As such, Adam gains a mechanical replacement and has to use other weapons.
- Green Rocks: Black Dust is a Dust variant shrouded in mystery. All that's known is that it's extremely rare and provides a substantial boost in power to fighting ability.
- Improvised Zipline: During the Atlas Manhunt, Jaune and his friends escape Glynda's penthouse to the adjacent building via Penny's Strings.
- Indy Ploy: So many of Jaune's insane but effective plans are created on the.
- Nice Job Breaking It, Hero!: Jaune blows up Mountain Glenn to kill the Grimm Dragon ... and inadvertently allows hordes of Grimm an easier way into the already devastated kingdom.
- Nobody Could Have Survived That: After losing an arm to Jaune, Adam is engulfed in an explosion during the second battle at Mt. Glenn, leading everyone to assume he died. So, imagine everyone's surprise when he not only turns up alive during the Battle of Beacon, but sporting a new robotic arm.
- Spared by the Adaptation: Due to the divergent timeline created by Jaune influencing the canon timeline with his actions. This includes:
- Roman: (Saved by Adam from Prison between Volumes 2 and 3 and later by Neo from the Vytal Stadium.)
- Penny: (Ruby stopped the match between Pyrrha and Penny due to Jaune buying time against Mercury and Roman.)
- Pyrrha: (Pyrrha did not confront Cinder and was occupied with the rest of the teams escaping Beacon.)
- Ozpin: (saved by Summer and Raven during the Fall of Beacon.)
- Amber: (Jaune and Ruby manage to rescue Amber out of the Vault under Beacon, averting her death from Cinder)
- Vernal: (Shes actually the Spring Maiden here and was found by Qrow, Oobleck, and Port rather then killed by Cinder.)
- Summer: Summer is alive in the story and currently traveling with Raven. Her survival is attributed to her Silver Eyes causing an incident and then being reported missing for so long that everyone but Qrow, Raven, Ozpin, and Jaune (unknowingly) knows of her survival.
- Violence Is Disturbing: Despite being rated K+, there are multiple examples of rather bloody or heartbreaking and violent scenes during the course of the story.
"Kahh!" Adam dropped to his knees, his katana loosened from his gripor to be more precise, it was cut off. His whole right arm from the elbow down was cleaved from its shoulder. An agonizing screech bellowed from his mouth as he held out his shortened limb".
- During the Prologue, Jaune mentions hundreds of Huntsmen and Huntress' slaughtered during the Fall of Beacon. Cardin is killed saving Jaune's life from Neo who was disguised as Pyrrha.
- In Chapter 35, Jaune cuts off Adam's right arm during the Second Battle of Mountain Glenn.]]
It was not a clean kill. The sound of flesh meeting steel was never enticing. In fact, one might say that it was disgusting in all manners. The blade went through and with it, blood splattered on the boy. His face, his hair, even his armor was soaked. Not a single bit of him was untainted by that color. Ruby cringed as she watched the whole scene play before her. Her eyes moved away on reflex but she forced herself to see it. She etched every moment of that kill into her mind and memorized every detail. She still gasped and held her mouth in response. But kept herself composed nonetheless".
- Jaune delivering a Mercy Kill towards General Ironwood to prevent him from being corrupted from Parasite Grimm was not an easy sight for Ruby and especially Jaune.
"When Glynda took a quick scan on her surroundings she immediately recalled seeing a beautiful reception here with flowers and decorations. She remembered seeing thousands of guest-filled chairs, food tables and enough colors to make a rainbow jealous. There was a beautiful ceremony held here honoring a great man and an equally beautiful speech being said. But now it has turned into a warzone, an arena for survivors and a tomb for the innocent. Piles of bodies littered across the floor, tables and chairs uplifted while giant bonfires burned out of control. The sprinklers that activated barely held them at bay while gunfire echoed endlessly in all corners. There were people running around, some screaming while a few others cradled onto their loved ones with blood soaked tears tracing down their cheeks".
- During Ironwood's Funeral aboard the New Beacon warship over Mantle, Cinder uses an army of Geist Grimm to take control of the warship, creates a Nasty Party by ordering her henchmen to massacre the reception, and then seizes control of the New Beacons weapon systems and annihilates numerous Atlas Warships which in turn devastates the city of Mantle.]]
