Tifa

Tifa Lockhart is a character in Kingdom Hearts II that originates from Final Fantasy VII. Her look in Kingdom Hearts II is modeled on her Final Fantasy VII: Advent Children appearance.

A young woman in search of a certain someone.

Unflinching, unrelenting, Tifa has looked far and wide.

Her journey won't be over until she finds the person she seeks.

Kingdom Hearts II
Tifa appears during one of Sora's visits to Hollow Bastion in Kingdom Hearts II, inspecting Ansem The Wise's study, looking for "a guy with spiky hair," but not elaborating any further.

The person she's looking for turns out to be Cloud, and she almost catches up to him during the Heartless invasion, but he chases after Sephiroth, leaving her to fight a large group of Heartless on her own. She is later the third person to fight alongside Sora in the Ravine Trail, preceeded by Yuffie and Leon, and followed by Cloud.

If Sora wins the optional Sephiroth boss fight, he can find Cloud and tell him that Sephiroth is waiting for their battle. It is as this confrontation with Sephiroth reaches its climax that Tifa finally catches up to Cloud. She tries to help Cloud, saying that all that needs to be done is to surround him in light, and telling Sephiroth that the darkness will always be there, but in a place that he can't reach. She fights with Sephiroth very briefly, then gives Cloud the light to overcome his darkness, after which the two men return to battle and disappear once again, leaving her to continue the pursuit.

After this, Tifa will give Sora the Fenrir keychain. Cloud and Sephiroth are the only Final Fantasy VII characters she interacts with; she never meets with Aerith, Yuffie, or Cid. However, Yuffie is debatable, because Tifa fights along side Yuffe in Round 10 in the Hades Paradox Cup. Although she appears in Hollow Bastion/Radiant Garden, much like Cloud and Sephiroth, it is unclear if it is her home world, though Cloud has been confirmed to originate from Radiant Garden.

Fighting Style
She possesses the same tremendous strength she did in Final Fantasy VII, easily capable of high level martial arts such as lifting a gigantic portrait of Xehanort, and kicking a wall hard enough to shake a whole room (her high physical strength being displayed in a comical way is a small running gag).

She can perform her final Limit Break attack called "Final Heaven", which enables her to send a massive energy blast at her opponent.

Trivia

 * Tifa was intended to be featured with Cloud and Sephiroth in the original Kingdom Hearts, but was removed due to time constraints.
