In the present, Rider is drastically different from the monster she was in history. She has her own motivations besides seeking the Holy Grail, and despite suffering through abuse, she stands tall and proud. Frequently demoralized, and unable to comfort Sakura, Rider is presented as a cold and silent woman, bound to her duty more than anything else. She is obedient to a fault, doing whatever one of a higher position tells her, without any questions. And she's a sticker for practicality, preferring plain clothes, and simply tying her ankle-length hair up in a ponytail. Rider is actually very intelligent to boot. Her manner of speaking is very eloquent, even if she doesn't talk much at all. One of her favorite hobbies is reading, and her thinking process is very logical and neutral.

However, what matters most to her is simple: peace. She wants nothing more than to live peacefully with Sakura, though she ironically must fight to get her wish. She is completely devoted to Sakura, and will not hesitate to kill others that are threatening her. She's the happiest in Heaven's Feel's True End, where the War is over.

That devotion is not solely to Sakura, however, and Rider is shown to be a woman of respect and truthfulness. In Fate, when Shinji sends her out to kill Shirou, she recognizes him as an honorable person and says that she won't brutally kill him. When off the battlefield, she proves to be charismatic and kind, and has an affinity for protecting those weaker. She never seems to lie, either, only with-hold information in the first place.

Underneath her fighting prowess and dark history, however, Rider has a lot of self-confidence issues. She frequently worries about her height, thinking being too tall will make her not appear cute. Social situations tend to make her nervous, and she will remain silent as often as she can. Her past haunts her more than what's initially apparent. She prefers being called just Rider, and would really like you to know what she doesn't have snakes for hair. She deeply, deeply regrets her actions back in Greece, and as such never uses her monstrous strength in battle--in fear that it will only help transform her back into a monster.

That doesn't stop Rider from being creepy, though. She is Medusa. She seems to slip into the persona of the monster, every now and then. The strongest example of this is probably in Unlimited Blade Works, when she makes a comment about plucking out Shirou's eyes and orgasming. And while she was not too keen on ambushing people in the street and drinking their blood for mana, the only part she was really against was "killing them."

Servant-wide abilities:
Servant classes: hundreds of times more powerful than your ordinary human. Rider is one of the more agile of the classes, and by far the fastest, able to move at nigh-supersonic speeds. She can nullify most magic thrown at her. She can become intangible when she wills it so, being able to pass through solid objects, and invisible to all but her Master. Though this form presents an advantage, she must switch back to her concrete form if she needs to engage in physical combat. As she is not mortal anymore, Rider cannot truly die. If she is injured, she will sink into spirit form and regenerate with time. Even if she is mortally wounded, all that will happen is her withdrawal from the war; her "spirit" will remain unharmed.

Note that as a Heroic Spirit, she will need a regular flow of prana to survive in this world, properly. Her independent action is C-rank, meaning she is able to exist without a Master for around 1 day.

Unique abilities:
Rider's eyes, called officially "Mystic Eyes" in the Nasuverse, will instantly petrify human flesh into stone, and hamper the magical energy of stronger beings. She also seems to be able to manipulate others' dreams, and sneak into them. Her signature weapon, which she can summon at will, is a pair of large iron nails fastened to the ends of a long chain.

With a prana boost, Rider is able to significantly raise her physical strength to monstrous levels, though she dislikes using this for fear of "relapsing" into a monster. She has a small amount of divinity as well (divinity equating with god-ship).

Noble Phantasms:
Breaker Gorgon -- it takes the shape of her blindfold, and completely blocks out the effects of her eyes. They can also take the form of a pair of glasses.

Blood Fort Andromeda -- Rider is able to set up a barrier in a fixed location, and drain the prana of all those who are within it. More specifically, it drains the occupants of their blood, and only those with magical energy are able to resist it. Those without it will die instantly, and the only ones who won't be affected by it in the least are other Servants, and high-class magi. Additionally, it acts as a barrier between the occupants and the outside world, as when activated, no communication can be done from the inside out. It stays in effect until Rider dies or wills it to dissipate.

Bellerophon -- A harness, bridle, and saddle capable of taming and amplifying tenfold the power of beasts. It does nothing on its own, but once used on a beast, it instantly bends to Rider's will. This comes hand in hand with her status as the Rider class of the War; she is able to tame and ride nearly any beast of any rank in her path, and with ease.

*She's regained some of these from her previous stay, and she'll be keeping them upon her return.
