If Freeza had won on Namek...

[withheldforprivacy]

...would he have gone to Earth to find dragonballs?

 

[Papasmurf]

He already tried to gain immortality when Porunga revived, so yes.

 

[Let's Go Fearless!]

Does he know that there's DB on Earth?

 

[Papasmurf]

Goku explained to him that they revived Freeza and his men's victims with the Earth DBs

 

[Let's Go Fearless!]

If that's the case then he'll definitely search it on Earth but he's gonna kill all the Z fighters first including Piccolo which mean DBs will be dead too.

 

[Papasmurf]

Piccolo would just troll him into killing him so there will be no Dbs left

 

[Jerk Store]

Piccolo: Come at me bro! You can't cause you're a scared little pussy!
