É o grande evento do canal CW com o crossover entre as suas séries de super heróis, começando na Terça em The Flash (que vai buscar a Supergirl à Terra dela para ajudar na luta contra uma ameaça extraterrestre), passando para Arrow na Quarta e acabando com Legends of Tomorrow na Quinta. Tudo isto acontece na semana de 28 de Novembro (Segunda) até 1 de Dezembro (Quinta) deste ano.
O trailer "Heroes Vs. Aliens" mostra um pouco do que vai acontecer, mas é muito pequeno. Confesso que também não quero saber muito mais para depois apanhar tudo de surpresa. Uma raça alien, "The Dominators", invadem o planeta Terra no episódio de The Flash e Barry tem de pedir ajuda a Green Arrow, a Supergirl e às Legends para conseguir parar esta invasão.
Marc Guggenheim, um dos principais responsáveis das séries do CW, falou sobre a inspiração que tiveram para este novo conflito, e como foram feitos visualmente os extraterrestres:
"This year, for our mega ‘Arrowverse’ crossover, we’re taking inspiration from a DC crossover from the late 1980s known as Invasion!, which featured an alien race called the Dominators, who’d previously vexed the Legion of Superheroes. We’re using cutting edge prosthetics and computer effects to achieve a feature film-quality look which is faithful to Invasion! artist Todd McFarlane’s interpretation of the characters."
Guggenheim explicou ainda que a inspiração em "Invasion!" é um dos arcos mais ambiciosos que já fizeram para o CW:
"This year, we’re doing by far the most ambitious crossover we’ve ever done. It’s basically a huge three-part story that also brings in Supergirl, so it’s crossing over all four shows. It’s telling one big epic movie of a story. It’s not setting up any other spin-offs, it’s just big, bombastic, huge action. There’s also some really poignant character moments. There’s a lot of plot lines, particularly I would say in Flash and Legends, that come to fruition in the crossover. It’s by far the most ambitious thing we’ve ever attempted. I want to say it’s by far one of the most ambitious things anyone in network television has ever attempted. It’s completely insane."
Eliza (Helen Slater) comes to town to celebrate Thanksgiving with her daughters. Alex (Chyler Leigh) decides it’s time to come out to her mother; Kara (Melisa Benoist) is shocked when Eliza suggests Mon-El (Chris Wood) has feelings for her, and Winn (Jeremy Jordan) and James (Mehcad Brooks) consider telling Kara the truth about the Guardian. Meanwhile, CADMUS unleashes a virus that instantly kills any alien in the vicinity so Kara enlists an unexpected ally – Lena Luthor (Katie McGrath). The epic superhero crossover kicks off tonight when Barry Allen (Grant Gustin) and Cisco Ramon (Carlos Valdes) seek Kara’s help with an alien invasion on their Earth.
When aliens called the Dominators attack Central City, Barry (Grant Gustin) speeds over to Star City to ask the Green Arrow (Stephen Amell) for help in stopping them. Realizing the battle against the Dominators is bigger than they thought, they track down the Legends of Tomorrow, and Barry and Cisco (Carlos Valdes) create a breach to bring back a secret weapon – Supergirl (guest star Melissa Benoist). Once all of the super friends are assembled, they come up with a plan to attack but a shocking secret related to Flashpoint is revealed and suddenly no one is sure who they can trust. Meanwhile, Wally (Keiynan Lonsdale) wants to join the battle against the aliens but Iris (Candice Patton) tells him he’s not ready.
Oliver (Stephen Amell) wakes up to a life where he never got on The Queen’s Gambit. Robert (Jamey Sheridan) and Moira Queen (Susanna Thompson) are alive and well. Laurel (Katie Cassidy) is his loving fiancée and their wedding is imminent. Everything seems perfect, but Oliver starts to notice small imperfections that make him question this new reality. Meanwhile, Felicity (Emily Bett Rickards) and the recruits take on a new threat with help from The Flash (Grant Gustin) and Supergirl (Melissa Benoist).
Legends of Tomorrow
After learning the Dominators’ plan for the world, the Legends must work together with The Flash (Grant Gustin), Supergirl (Melissa Benoist), and Green Arrow (Stephen Amell) to kill them once and for all. Meanwhile, Stein (Victor Garber) figures out, with the help of others, how the team can terminate the Dominators, but is distracted by the aberration he realizes he created in 1987. Brandon Routh, Franz Drameh, Dominic Purcell, Maisie Richardson-Sellers, Nick Zano, and Caity Lotz also star.
