Benevolent Architecture: An uncanny amount of the scenery is implausibly handy for jumping/climbing/hanging/swinging/free-running around on. Which is lucky, since there's a distinct imbalance in the ratios of really-high-places to staircases/ladders/jetpacks, smooth stable floors vs. fataldrops, etc.
Counter Attack: Plenty of it in the Sands of Time trilogy. In combat, the Prince is able to counter most enemy attacks and deal them a devastating blow. However, enemies can sometimes counter the counter attack, forcing the Prince to block or counter the enemy's counter attack. There are instances where the Prince and his opponent will exchange half a dozen counter attacks before one misses their timing and gets hit.
Did You Just Punch Out Cthulhu?: The Prince is surprisingly competent at this. In the canon ending of Warrior Within, he kills both the Empress of Time and the unstoppable beast that makes sure the timeline stays correct. In The Two Thrones, he kills a god of time. In The Forgotten Sands, he kills Ratash, an Ifrit and supposedly invincible.
Leap of Faith: Used several times throughout the series, such as with an unlabeled potion in the first two games (it turned out to be a slow-fall potion), to a daring leap in the second game off a ledge into the next screen to land on a horse statue (which promptly comes to life).
The Many Deaths of You: The above-mentioned selection box of unpleasant exits gives rise to an exciting assortment of death animations. The original game alone memorably had nightmare-inducing clanging metal jaws in mid-corridor that guillotined you in half if you mistimed stepping through them. Alternatives were being run through by enemy swords, impaled on spikes, and hitting the bottom of deep pits with a skull-cracking smack.
Nominal Importance: Averted. The Prince is never named except in The Movie, and several of the games have the majority of characters go unnamed.
In The Sands of Time, the Prince is voiced by Yuri Lowenthal. In Warrior Within, he's voiced by Robin Atkin Downes. In The Two Thrones, he's again voiced by Lowenthal, with Canadian actor Rick Miller providing his inner "Dark Prince" voice. There was talk during development that Downes would voice the Dark Prince, but ultimately that didn't come to pass. Also in his brief Foreshadowing appearance in the second game the Dark Prince is played by Michael Rudder.
Played straight with Kaileena (modeled after Monica Bellucci and voiced by both her and sound-alike actress Alicyn Packard in Warrior Within and Sarah Carlsen in The Two Thrones) and Farah (Joanna Wasick in The Sands of Time and Hellen King in The Two Thrones).
Pop-Star Composer: Stuart Chatwood, multi-instrumentalist and former bassist for The Tea Party, wrote the soundtracks to all the Prince of Persia games made by Ubisoft.
Reset Button: A key part of the story and gameplay in the Sands of Time trilogy. Unlike many examples, this one is often seen more positively, as the Reset Button and its implications are major elements of the plot, not just a way to keep the status quo.
Sealed Army in a Can: Pretty much any major army from Sands of Time onwards. At some point, one of the characters will even warn everyone present about what will happen when said army is released. Naturally, no one listens.
Stripperiffic: All female characters, at one point or another (particularly the women in Warrior Within).
Take Your Time: In The Sands of Time trilogy, some ledges can support the Prince indefinitely, but collapse immediately after he steps off them.
Timey-Wimey Ball: It's never exactly clear how time travel/manipulation works in the Sands of Time trilogy.
"Most people think time is like a river, that flows swift and sure in one direction. But I have seen the face of time, and I can tell you — they are wrong. Time is an ocean in a storm."
Trilogy Creep: The Sands of Time storyline got a fourth installment, conveniently about the time the film is released.
Two-Part Trilogy: The original games were slated to be this. The first game was a self-contained story that wasn't initially meant to be anything bigger. A sequel was made, however, and it ended on a Cliff Hanger. This was ultimately subverted, since the planned third game never happened, and the eventual sequel, Prince of Persia 3D, was completely unrelated.
Video Game Cruelty Potential: Throw the Sands of Time Prince down pits or into spikes as many times as you like! You've still got the necessary time-rewinding sand, right?
You Can't Fight Fate: A running theme that is subverted and finally double-subverted throughout the Sands trilogy, but it's best defined in Two Thrones. Every single thing the Prince has tried to prevent from happening in Sands of Time and Warrior Within comes to pass in the third game, except one: Farah lives. The Prince accepts it in the end. Similarly, Shadee and Kaileena know their actions are futile but go against the time-line anyway. However, Kaileena's motivations are ret-conned into "I knew this would happen all along and all my actions were to make sure it did."
You Get Knocked Down, You Get Back Up Again: Averted; in the Sands of Time series, enemies can and will attack you while you're down. Fortunately, you can rewind time, block while on your back, or perform a roll to swipe at their feet and get back up.
