"The Core Timeline is an amalgamation of chaos. The so-called real world has been overlapped with the realms of movies, comic books, anime, and more. Portland, Oregon is not immune to this. The City of Roses in the Core Timeline has its own heroes. Mainly the Aegis Organization, a local branch of The Foundation, originally from an alternate version of the Marvel Universe, destroyed in a cataclysm, but reborn here. And when a massive demonic invasion hits the world, Aegis must live up to its mythological namesake and be Portland's defense, for they are the City of Roses' only hope..."
Coreline: Invasion Of Portland 
, by L1701E, is part of the Coreline Shared Universe.
Warning! Contains spoilers for The Shikigami Ranger and the Monster Mashers, taking place at the same time as this other story.
This story has the following Tropes:
- '80s Hair: Amir "Gyral" Khosrow's hairstyle is meant to evoke Keith's mullet in Voltron: Legendary Defender. It also fits with his being a fan of 1980s pop culture.
- Adaptational Nationality: The Alternate of Rosalind Price that leads the Portland Aegis team is German-American because
that is the nationality of her actress. - Adaptation Name Change: Aegis's Chrome is named Jennifer Swann instead of Swensen. Per Word of God, it was in homage to pro wrestler Rich Swann.
- Affirmative-Action Legacy: Silver Sabre is one of those. The original Super Sabre was the white Martin Fletcher. His descendant, Keiko Miyamoto, is a bisexual Japanese-American.
- Age Lift: The Outlaw Star alts that appear here are ten years older than their "canon" selves.
- The All-American Boy: Giovanni "Jack" Magniconte is meant to be a modern take on the concept. The story establishes that before Aegis, he was a high school quarterback, popular with girls, and even managed to have friends from the various archetypical high-school "cliques". His codename, "All-American", is a reference to his being an astounding athlete pre-Aegis.
- Ascended Extra: Aegis's roster is full of obscure characters, and even versions of characters that were originally not native to the mainstream Marvel comics universe, most notably versions of Giovanni "Jack" Magniconte and Jennifer Swensen from Marvel's New Universe line.
- The Atoner: Haywire joined Aegis to atone for his working for a supervillain known only as the Chronobreaker.
- Author Appeal: The author is a big fan of obscure characters. A couple of the characters in this story have literally only appeared in ONE comic book and have never been mentioned again before appearing here.
- Back from the Dead: Played with in Haywire's case. The Avengers thought he died in the miniseries Avengers: Celestial Quest, but this story establishes that it was faked, and Haywire was actually brought forward in time.
- Badass Normal: Luther Banks has no superpowers, but he makes up for it with Marine grit and his skills as a sniper.
- Big Bad: Hexxus, the pollution spirit from FernGully: The Last Rainforest, Emerges in the middle of the chaos and exploits the spiritual pollution that the demons are causing to grow stronger.
- Canon Immigrant: Aegis's roster has a few. Rosalind Price and Luther Banks are originally from the Agents of S.H.I.E.L.D. television series. Taryn Fujioka, Aegis's PR expert, is based on the character from X-Men: Evolution. All-American and Chrome are based on characters that appeared as part of Marvel's The New Universe line in the 1980s. It's also established that Aegis's original timeline had a version of Henry Clerk, the Big Bad of another obscure Marvel imprint from the 80s: The Shadowline Saga.
- Chrome Champion: Chrome has the power to turn her skin into metal, much like the X-Men's Colossus. Also like him, she is super-strong and practically indestructible in her metal form. Unlike the original New Universe version of the character, Jen can change back to normal and got her powers thanks to Terrigenesis.
- Crisis Crossover: The events of this story take place in the middle of all of the world-wide chaos that is shown in The Shikigami Ranger and the Monster Mashers.
- Color-Coded Characters: As a nod to Power Rangers, the main Agents often wear clothing of one particular color: Red (Chrome), Blue (All-American and Silver Sabre), Yellow (Gyral), Green (Haywire), Purple (Quartz)
- Composite Character: Among the secondary characters of the story are alts of the Outlaw Star crew that have been amalgamated with various Marvel characters, mainly members of the Guardians of the Galaxy. Also, another is an alt of Cyclops that is also a Kamen Rider.
- Doctor Starwind is an amalgam of Gene Starwind, Doctor Strange, and Star-Lord.
- "Lucky" Melfina is an amalgam of Melfina, Clea, and Domino.
- Aisha Clan-Clan is melded with Drax and Tigra.
- Jim Hawking is melded with Rocket Raccoon and Bullseye.
- "Twilight" Suzuka is melded with Gamora and Psylocke.
- Crisis Crossover: Not only do we get a different point of view of a major In-Universe event but one of the major characters of the Trope Namer comic book event directly compares the Core Timeline to it.
- Deconstruction: Supergirl remembers her death at the hands of the Anti-Monitor in Crisis on Infinite Earths, and it has left her traumatized. She admits to having nightmares about it, and seeing the red skies TERRIFY her, as she believes they are a sign the Anti-Monitor is coming back. After all, if she could come back, so could he... To Reincarnate in Another World is not always pleasant. It's reconstructed by Supergirl saying that she is regularly attending therapy sessions, and she's in a place where she can actually get some help for her trauma.
- Also hinted at is a mentioned Noodle Incident in which Haywire encountered an alt of his deceased girlfriend Inertia during an Aegis investigation and got really freaked out. For some, the Coreline can bring up some emotional issues.
- Disco Dan: Somewhat with Gyral. He's a big fan of 1980s pop culture and movies.
- Elsewhere Fic: This story takes place at the same time as The Shikinami Ranger and the Monster Mashers, over on The Other Rainforest.
- Fanboy: Jack Magniconte admires Captain America.
- Funny Animal: The alt of Jim Hawking that appears in this story is an anthropomorphic raccoon. Which makes sense as he's an amalgam of the original Jim and Rocket Raccoon (as well as Bullseye).
- Half-Human Hybrid: Keiko "Silver Sabre" Miyamoto is sort of this. She is a mutant with the power of superspeed, but she also has Inhuman genetic markers, which allowed her to undergo Terrigenesis. When she did, she gained a "telepathic radar", allowing her to sense people around her, but she can't read minds.
- Happily Married: Doctor Starwind and "Lucky" Melfina are this. They got hitched not long after arriving on the Coreline.
- Lawyer-Friendly Cameo: Quartz is fond of a tabletop game called Fiends and Fjords.
- Legacy Character: Keiko Miyamoto, aka Silver Sabre, is a descendant of Martin Fletcher/Super Sabre, a character that first appeared in Uncanny X-Men #215 (March 1987). She inherited his mutant power of superspeed. Her father was also a Kamen Rider-esque superhero in his native Japan called "Captain Silver". Her codename of "Silver Sabre" is a way of honoring both her parents.
- One of Aegis's allies is Jerome "Jerry" Chang, an Inhuman consulting detective with cryokinetic powers that took up the "Iceman" moniker in honor of his friend in his home universe, the X-Man Robert Drake.
- Manly Facial Hair: Doctor Starwind sports an epic handlebar mustache.
- Noodle Incident: Some have been mentioned.
- Origins Episode: The origins of the various Aegis agents that appear are told throughout the story.
- Purpleis Powerful: Andy "Quartz" Cortez has the ability to create crystals. They're purple in color. He can create tough barriers with them, or shards that are razor-sharp.
- Race Lift: In the original New Universe comics, Jennifer Swensen was a white redhead. Her Aegis counterpart, Jennifer Swann, has a black father and Native American mother. Still retains the red hair, thanks to Terrigenesis.
- Red Skies Crossover: Literally, with the skies over Portland getting a deep red tint Crisis on Infinite Earths-style while all hell breaks loose, which is even lampshaded...by an actual veteran of the Crisis.
- Reincarnate in Another World: What happened to Supergirl. It left her with mental scars.
- Shout-Out: The Jim Hawking alt here speaks with a Cockney accent. This is a nod to Greg Ellis's vocals as Rocket Raccoon in Ultimate Marvel vs. Capcom 3 and The Avengers: Earth's Mightiest Heroes.
- Solar Punk: The city of Portland's interest in going green has increased after the Vanishing, with lots of hanging gardens and green power. This is a problem for Hexxus, who decides to change that. Because of the Vanishing, Portland itself has become the very antithesis of his existence.
- Take That!: When the second Iceman recalls learning of the events of Death of X and Inhumans vs. X-Men (those crises never happened in his native timeline), he thinks the whole thing was pure insanity. The author disliked those stories as he felt they made the X-Men and the Inhumans look like complete idiots. Per the author, those stories never happened in Aegis's original timeline either.
- The Bus Came Back: Combined with Ascended Extra in the case of Jacqueline "Nightcat" Tavarez. She originally only appeared in one comic from 1991 and that was it. In Aegis's original timeline, she continued her musical/crimefighting careers, until she encountered Aegis. During that point, the serum that had empowered her had stated to cause her DNA to destabilize, potentially causing a painful death. Aegis was able to cure her, but at the cost of mutating her further into the feline appearance she has at the start of the story.
- Also applies to Hal "Haywire" Danforth. He appeared in the 1980s Squadron Supreme miniseries and died in the 2001 miniseries Avengers: Celestial Quest. The story explains his return from the grave (It turns out he never really died, he was brought forwards in time by a supervillain), but also gives an explanation as to how he got his powers in the first place. The story also delves into his personal life (notably revealing he is Jewish), and also explains where he was where Nighthawk recruited him to the America Redeemers. These are things the original Squadron Supreme miniseries never did.
- Also applies to Hal "Haywire" Danforth
- Trauma Button: One of the secondary characters is a Pre-Crisis Alternate of Supergirl who Emerged on the Core Timeline after dying in the Crisis on Infinite Earths, and obviously seeing the red skies and apocalyptic madness make her start to fear the Anti-Monitor may appear.
- There also was a Noodle Incident mentioned in which during an Aegis investigation, Haywire encountered an alt of his deceased lover Inertia. Naturally, it freaked him out. It led Haywire to grumble he hates the Coreline sometimes.
- Wrench Wench: Chrome is introduced fixing up an Aegis vehicle. The story also established that she worked as a mechanic before gaining her powers and becoming an Aegis agent.
