Based on available information and feats, Tarble is generally considered the weakest full-blooded Saiyan.
Tarble, Vegeta's younger brother, was exiled from Planet Vegeta by King Vegeta due to his lack of fighting ability and his unsuitability as a warrior. This immediately sets him apart from other Saiyans, who typically value strength and combat prowess above all else.
Here's a breakdown:
- Lack of Fighting Prowess: Tarble's exile explicitly states his weakness as the primary reason. Saiyans like Nappa, Raditz, and even weaker members of Frieza's army demonstrated far more destructive potential.
- Absence of Combat Feats: Throughout his limited appearances (primarily in the Dragon Ball: Yo! Son Goku and His Friends Return!! OVA), Tarble demonstrates virtually no combat skills. He relies on others for protection and shows no inclination towards fighting.
- Comparison to Other Saiyans: Even considering Saiyans of lower power levels, Tarble stands out as exceptionally weak. Other full-blooded Saiyans, such as those encountered in the Saiyan Saga, possessed the Saiyan traits of aggression and a desire for battle, traits largely absent in Tarble. Even the Saiyan babies in Universe 6 showed far more potential.
While other Saiyans might have started weaker, Tarble's never shown an interest in becoming stronger and was exiled for being so weak he couldn't protect himself. This implies a severe lack of power compared to even the most baseline Saiyan warrior.
