Do you think the game protagonists are siblings?

I mean its not impossible most of them look like each other and they have the same mom.

What do you guys think?

Per game, or what?

You and your rival (IE, other character you can play as) share the same mom only if you play as either of them. But per game, it's not the same mother...

I don't know what you mean.

May and Brendan are definitely not siblings. They live in different houses and have different moms.

I don't understand what you mean because the topic is very vague.

But no, I don't think so. I don't think the player character is a sibling.

You can visit Red's mom in gen 2, so the protagonist from those games wouldn't be a sibling.

It's highly unlikely because the only way for that to happen is if they all have the same dad. And there's also the timeline jumps in the games and regional distances to consider here.

I prefer to call them alternate universe counterparts (which can be used as an excuse for almost every other discrepancy in the games).
