Tifa is stunning, but it was after Cloud's mental breakdown and invalidity in the Lifestream that I became particularly drawn to her. Tifa was the one who entered the shattered fragments of his mind and gently encouraged and coaxed him back into control. Sephiroth's plan would have succeeded if Tifa hadn't intervened, and Meteor would have destroyed the planet.
Tifa is a true unsung hero, with the heart and face of a loving angel.
Final Fantasy VII is set in another planet with an unknown year so we will never know her real age. She is 20 year old in the game but we don't know if Final Fantasy VII is set in the past or future because its not on Earth.
Tifa is my favorite because she is just a regular girl. There was no descendant of a lost race with magical abilities, no superhuman enhancement, not even a weapon. Just a regular girl who fights with her fists. Everything she has or has learned is the result of her own hard work. Her life was turned upside down, but she pulled herself together and emerged physically and mentally stronger. When Cloud is not around, she is the leader.
Tifa always have a place in my heart. When I was younger, I looked up to Tifa, an older female figure. She wasn't scared to reveal her vulnerability, but she had more than enough strength to deal with any situation. She wasn't scared to fight for and defend those she cared about, even if it meant jeopardizing her own survival and well-being.
