how can i make different enemies spawn (in my case it's different phrases) with the spawn item rando

how can i make different enemies spawn (in my case it's different phrases) with the spawn item randomly?

I'm making a game about fake news and I should make several sentences spawn (in my case they are the "enemies" of the game) which the character will then have to shoot down with bullets.

how could I do?

Make a family and then spawn the family. It will randomly spawn an object (enemy) from that family.

I would like them to appear only once though, not multiple times. They are sentences ("fake news") that must be practically destroyed. Being that they are different sentences therefore, I have to appear only once

yes, i mean that. I'm doing a game for my university thesis on fake news. it should be a revival of space invaders only instead of enemies there is fake news
