No, Bardock is not alive.
The Dragon Ball series confirms that Bardock, Goku's father, died during the destruction of Planet Vegeta by Frieza. While there have been alternate timeline depictions and special episodes where Bardock survives, in the main Dragon Ball canon, he is deceased.
Here's a breakdown:
- Original Death: Bardock, along with the majority of the Saiyan race, was killed when Frieza destroyed Planet Vegeta. This event is a key part of Goku's backstory and motivation.
- Confirmation in Later Arcs: Even in the more recent arcs of Dragon Ball Super, such as the Granolah the Survivor arc, Bardock's death is treated as an established fact. The evolved Gas even recognizes Goku as Bardock's son, acknowledging that Bardock is long dead. Goku's emotional connection to his Saiyan heritage is emphasized when he hears a recording of Bardock's voice, solidifying the reality of Bardock's past.
Therefore, while alternate versions or "what if" scenarios might exist, the canonical answer within the main Dragon Ball storyline is that Bardock is deceased.
