Dragon Ball Z (Attack Of The Saiyans)
AlexxdaGR8 for Tien
He was originally a student of the Crane School who desired revenge against Goku for defeating his mentor, Mercenary Tao, but realized he was on the wrong side with the help of Master Roshi. He battles alongside the other Z Fighters against major threats to the Earth, often courageously engaging enemies far more powerful than himself.[9] However, he spends most of his time training with his lifelong best friend, Chiaotzu.
Tien Shinhan was originally a cold-hearted and ruthless warrior, never caring for anyone's life with the exception of his fellow students and mentors. This brutality can be plainly seen when he crushes Yamcha's and another fighter's leg during the 22nd World Martial Arts Tournament. However, he finds a lifelong best friend in Chiaotzu, for whom he cares deeply, and vice-versa. He highly idolized his mentor Mercenary Tao and desired to be a famous assassin like him. Due to Master Roshi's and Goku's influence, he changed his demeanor and became one of the most respected warriors on the planet. Before he transitioned to the good side, he planned to kill Goku during the World Martial Arts Tournament as he was seen as a threat to himself and his cohorts.

Master Roshi... I have betrayed the Crane spirit. In its place, I have learned how to wield my martial arts in ways I never imagined before...But I am afraid my training has left me at an impasse.
And I can certainly forget about ever surpassing him...
...Yes, Master. I wish to master my skills to protect those who I hold dear. While I do so, I want to continue searching for the true meaning of martial arts.
...I don't know if I will or not. But if I keep doing everything I can to strive for that goal...I think that'll be what leads me to become truly strong like Goku...
...Yes, Master. Once, I thought martial arts were a tool to dominate others. But the skills I've learned from you are something entirely different. There is warmth... and kindness to them.
What I have learned is that there are some things in my life I must absolutely protect.
(Listen up, Goku! I think I finally taken a step forward toward your strength.)
Until I figure this out, no matter how strong I get, I well never attain Goku's strength.
I also think I understand where Goku's true strength lies...
(I'm going to be a different man when we meet again!)
