In the non-canon 13 Riders Special, when Knight sacrifices himself by jumping in the way of Verde's Final Vent, instead of lying down and dying, he immediately gets back up and Final Vents him right back. He is clearly injured the whole time, and dies soon after.
Which is then followed by A now deck-less Shinji picking up the now user-less Knight deck, using it (going straight into survive in the process) and then either getting into a massive rider battle royale (which is basically everyone unloading their Final Vents onto him, or destroying the source of Mirror World, escaping in the process, depending on which of the Multiple Endings you go by.
When Shinji finally gets to be the cool one for the first time, saving an injured Ren from Volcancer.
Tezuka, the man who gave Ren the Survive Shippu card, took a direct hit from Ouja's Final Vent. Buying time for Shinji and Tezuka to run away, Ren slowly draws the card as, true to its name windy gales blow through the Mirror World. Ren loads the card, transforming his visor to the Dark-Visor Zwei, and takes out the Dark Blade as he changes into Survive Form, his flowing cape billowing in the wind. He then proceeds to completely decimate Ouja, and probably would've finished him off for good were it not for the Mirror Monster getting in the way.
The first time we saw Dragredder turn into Dragranzer, and then into the most awesome Cool Bike ever.
Ryuki Vs. Ryuga. No flashy moves or the usual Toku camp. It was just Shinji against his copy who was a pale imitation of the real thing, in a brutal fistfight. It ends when Shinji, having been punched all the way back to the building, gives a wordless challenge by simply drawing the only card in the entire fight: The Final Vent. Ryuga responds to his challenge to settle once and for all who the real one is, ending with a Rider Kick showdown that ends with Shinji slamming Ryuga to his death.
And there's Odin's reaction. While the punch didn't hurt him, it did manage to shock him shock him since he never expected Shinji to know where he'd teleport. And there's the fact that he actually hit him since Odin's Teleport Spam meant he's hit a total of three times in the main series.
Episode 40. A 7-way free from all, from Knight vs. Alternative Zero on a Final Vent clash, to Ouja vs Tiger, and ends with with Imperer's monsters joining the fight and Zolda, and Survive Mode Ryuki. Truly awesome.
When a Rider goes up against Kamen Rider Ouja, they can never put up a decent fight. Such is not the case with Tiger. He is disarmed of his Wolverine Claws, but still fights with his Axe, being one of the few Riders to resort to using their Weapon Visor. He attacks Ouja with Destwilder, who counters with Metalgelas, and freezes Venosnaker just as Ouja prepares to use his special Final Vent. Tiger forces Ouja to resort to using the weakest Final Vent after having no Cards left to counter, and still lived to tell the tale... until his Heroic Sacrifice.
Combined with Tear Jerker, Shinji's final stand against the Mirror Monsters in episode 49. Wounded by a Mirror Monster while protecting a little girl, Shinji still musters up the strength to fight. He and Ren manage to kill several monsters before Shinji gets disarmed, and even then he kills some more with his Rider Kick. Once they go into Survive Form and unleash their Final Vents, they manage to destroy every single monster rampaging through the city streets. And epic last stand for a noble Rider.
