17 The Day A New Demon Was Born (Code Geass)

IMDb Rating: 7.6/10

Though this show is popularly commended for having a great ending, it also debuts very strongly. Code Geass' first episode masterfully sets up its world and introduces its key players, accompanied by stunning visuals and a fantastic opening theme.

The one-of-a-kind fictional war rampaging its world is enough to get anyone fully engaged, along with each character's intense personal conflicts and issues. Every episode has its strengths, but things all started with its fantastic debut.

IMDb Rating: 7.7/10

The first episode of this beloved shonen series is a great start that excitedly introduces viewers to the incredible world of Fullmetal Alchemist. It also introduces the Elric brothers, their motivations, and their cool abilities.

Edward and Alphonse quickly become everyone's favorite anime brothers while they work hard to thwart the plans of a rogue alchemist. The world and its intricacies are intriguing and fantastical, plus the animation is impressive. The music is impactful, and the characters are especially fun to watch and learn about during their debut.

15 Encounter (Elfen Lied)

IMDb Rating: 7.8/10

Elfen Lied is a show that many people assume to be nothing more than a gorefest. People who have seen the first episode assume this to be the case, but then the show expands on many themes later on and lets everyone know why it's remembered so fondly to this day.

That being said, there's no denying that the incredible gore and carnage of the first episode both do a great job of making Lucy seem like a psychotic individual. However, it's the events she goes through that turn her into such a diabolical figure, with the anime slowly humanizing her character over time.

14 Easy As Pirozhki!! The Grand Prix Final Of Tears (Yuri On Ice)

IMDb Rating: 7.8/10

Fans of romance shows can't simply watch the debut episode of Yuri on Ice and not want to watch more. It's charming, intoxicatingly sweet, and stunningly beautiful, topping the sports anime charts, along with the romance anime charts.

The absolute bop of a theme song alone will make viewers want to keep watching, just so they can listen to it all 12 times, once at the start of every episode. The first episode sets up the story wonderfully and will continue to be a fan favorite for years to come.

13 Let You Down (Cyberpunk: Edgerunners)

IMDb Rating: 7.8/10

Cyberpunk: Edgerunners is a show many people have heard of by this point. The anime has become a sensation, with David's story of being Night City's biggest edgerunner being equal parts epic and tragic.

12 Surprised To Be Dead (Yu Yu Hakusho)

IMDb Rating: 8.0/10

Before working on Hunter x Hunter, Yoshihiro Togashi penned Yu Yu Hakusho. This anime started on a strong note, even if the conclusion felt pretty rushed.

9 Tragedy (Tokyo Ghoul)

IMDb Rating: 8.2/10

It's a shame that Tokyo Ghoul's anime adaptation fell off the rails since the anime definitely started on a high note. Watching the helpless Ken Kaneki almost be devoured by a ghoul before turning into one in a cruel twist of fate made for a masterfully crafted debut.

Over time, Kaneki goes through another traumatic experience that turns him into a cannibalistic ghoul who acquires the powers of most people he fights. This makes him one of the strongest characters by the end of the manga.

8 Cruelty (Demon Slayer)

IMDb Rating: 8.3/10

Demon Slayer is one of the biggest names in anime right now. The incredible wave of attention brought forth by episode 19 turned the anime into an extremely popular piece of media that fans absolutely loved.

The first episode was more than enough to wow players, with the senseless killing of Tanjiro's family being a truly shocking event that got many viewers interested in this shonen series.

6 Flashing Before My Eyes (Erased)

IMDb Rating: 8.5/10

The concept of this mystery anime isn't exactly new. The Butterfly effect/time-traveling trope has been featured in plenty of movies and shows over the years. However, this show freshens up the concept with relatable characters, nail-biting high stakes, and a sense of urgency that keeps the viewer wanting more.

Erased has gained plenty of praise for its great soundtrack, intense plot, and well-developed characters. It's pretty fast-paced, but it really works out well in this bingeable, one-season series.

Spy X Family is one of the more popular feel-good anime to make the rounds in modern times. The hype for this show was through the roof, and the first episode made it infinitely clear why so many anime fans were waiting with bated breath for the pilot to drop.

The introduction of Twilight and Anya is near-perfect, and the building blocks for a lovely fake family are set from the get-go in a wonderful pilot that builds up this relationship between both characters. Once viewers get through the first episode, Yor and Bond become a part of the family and make for an endearing anime full of action and comedy.

4 Dog & Chainsaw (Chainsaw Man)

IMDb Rating: 8.7/10

Chainsaw Man's twelve episodes may have felt painfully brief, but most people loved how incredible the animation was from the very first episode. Denji is a tragic protagonist who is revived by his pet, Pochita, after things go very wrong for him.

People love this intro for how perfectly it introduces Denji, and his transformation to become the Chainsaw Devil is pretty amazing to witness.

2 To You, In 2000 Years: The Fall Of Shiganshina, Part 1 (Attack On Titan)

IMDb Rating: 9.1/10

With such a unique concept unlike anything seen before, Attack on Titan did a fantastic job introducing its terrifying world of titans and humans. The debut was disturbing and scary while accurately instilling the fear and hatred that Eren and his friends have for the Titans into every viewer.
