The show has undoubtedly one of the more "CGI-to-death" fight scenes. Nevertheless, one must not discredit the very first battle where Takumi, forced to wield the Faiz Gear, simply does a side kick on the first Monster of the Week and it explodes.
Episode 4. Yuka's epic revenge against the Alpha Bitches who made her life hell.
This one needs context. Kaido, Kiba's friend, had an accident that broke his hand and rendered him unable to play his guitar anymore. Yuka finds out that his professor had a hand in the accident, rigging his motorcycle so that the brakes won't turn on. Kiba goes and confronts the professor, who coincidentally is also an Orphnoch, and the two duke it out all while Kaido plays the guitar to Yuka one last time. What Kiba says to the professor before his transformation is also epic.
Both Kiba and Takumi's pre-transformation speeches are perfect. Both them and the fight afterward are showed as Kaido plays his guitar, making them quiet, subdued moments that are no less epic than any of the other fights in the show, especially since Takumi's speech essentially becomes his defining trait
Takumi: Did you know? When you have a dream, there are times when you get hurt, and times when you get really fired up... Or so I hear. *Flips out Faiz Phone* I don't have dreams. But I can protect dreams.
Kiba: Did you know? A dream is a curse. Those who fail are cursed forever... Or so I hear. *Orphenoch trasnformation begins* Your sin... IS HEAVY.
Episode 17. Takumi's been going through a rough time fighting Orphenochs as he's essentially killing people, but then he looks at all the people that won't die when he fights, and declares his will to fight. Two Orphenochs take him on, and he beats down BOTH, all to the badasssymbolic tune of Justifaiz.
Of course, try creating a hovering, rocket-powered bike without it! Delta's debut, when he breaks out the Jet Sliger against Faiz and Kaixa, has to be seen to be believed. The Delta powers are generally more awesome when in the hands of bad guys, in fact.
Actually, that's not Delta's debut, just the first onscreen transformation into it. But Delta's actual debut and its first actual user are themselves awesome. Up until she's shanked by Sawada before she gets to have an onscreen transformation, Saya Kimura, sweet and unassuming as she is towards the main cast, is an often overlooked awesome female Rider. That ominous scene where Faiz and Kaixa see an Orphnoch dying in flames while Delta looks ominously? That's her. Also, when she drives Itsuro away in fear. And her plan to pass on the Delta Gear? Infiltrate Keitaro's shop, and while her sweetness and nekojita trait weren't a facade, she does test Takumi on how he feels about power, knowing full well the addictiveness of the Delta Gear's. This being a Toshiki Inoue show, however, most female Riders seem to get the short end of the stick, so she gets robbed of her chance in the actual spotlight. Nevertheless, for this troper, Saya Kimura is arguably better than most of the later users of the Delta Gear, even Kitazaki.
The Movie, Keitaro's short-lived but awesome stint as a Rider.
Episode 40. Good god Episode 40. The "triple henshin" at the end remains one of the most awesome moments not of the series, but of the entire Heisei era! It's perhaps one of theSignature Scenes one might think of with Kamen Rider in general.
This one takes context. The Riders of this series are very much not on the same page. On top of that, Takumi himself is suffering from a Heroic BSOD around this time. So he officially finally gets himself through it as he and the others put their differences and own agendas aside, and for the first time ever, the three Riders stand together, enter their transformation codes, and power up to do battle. It was quite a moment.
The theme song starts up as Takumi declares his intent to fight as a human, as Faiz. EPIC.
Also, the zoom on Takumi's hand flick. That flick made this troper shiver in awesomeness.
Faiz Vs. Orga was simply epic, as the brawl was fought in both their Rider Forms and their Orphnoch forms, and one of the bigger moments is when Faiz rider kicks Orga's sword, now charged into a Big FreakingLaser Blade, and it causes a freaking large shockwave that cuts the entire roof of the stadium and even some Orphnochs while they're at it!
Don't forget Faiz vs Psyga. A high speed chase using Faiz Axel Mode ending up in that stadium in a very exciting battle. How does it end? Right before Psyga bifurcates Takumi, Mari screams his name and tosses him his Faiz Edge. Takumi quickly activates it and blocks Psyga's Exceed Charge right before slicing into Psyga himself. Takumi then activates his OWN Exceed Charge, making the Faiz Edge grind brutally through Psyga as he finishes him off with a massive Sparkle Cut.
Now that it's out: Takumi was a major part of Kamen Rider Wars and Kamen Rider 3 and the multi-episode Kamen Rider 4 special. Kusaka and Kaido got significant roles in Kamen Rider Wars and Kamen Rider 4, respectively. We're talking a mini-season-two in films that's reminiscent of (if not quite as big as) Den-O and Gaim! You'll be able to "Open your eyes for the next Faiz" for long after what looked to be the end.
