Dragon Ball: The Strongest Training

As Earthlings, they are inherently limited by their natural aptitude. In the original Dragon Ball series, Krillin's power level was recorded at 1,083 during the fight against Nappa, with a maximum of 1,700 when going all out. Therefore, setting Krillin's initial limit at 1,500 aligns with established canon. At the same time, Yamcha's power level was around 1,400, which illustrates the general ceiling for Earthlings' potential.

Namek Saga:

Krillin experienced a slight increase in strength after his battle with Vegeta. He also engaged in mental training with Gohan during their journey in the spaceship. His power level was roughly 1,500 at this point, as confirmed by Zarbon's scouter.

Post-Great Elder's Unlocking of Potential:

After the Great Elder on Namek unlocked his latent abilities, Krillin's power level shot up to 13,000 (officially recorded). This unlocking raised his potential limit to approximately 100,000.

During the Battle with Frieza:

Krillin's power level reached 75,000 by the time he fought Frieza.

Tien Shinhan:

Tien Shinhan's power level stood at 1,823, slightly higher than Krillin's due to his lineage as a descendant of the Three-Eyed People. This unique heritage means Tien is not a pure Earthling, granting him a natural edge in potential.

With the aid of the auxiliary system, Krillin now has the ability to repeatedly break through his natural limits. Through rigorous training and perseverance, he has the potential to ultimately surpass Goku himself.
