I remember a rumor saying that Iris is actually based off an in-game character, so I'll say yes to her being in the game. However, I don't think there's any relation to Aloe. It looks like Dento will be around too.
You do realize that a child's parent don't have to have the same skin tone as them to be related, right? IE: My father is dark, yet I'm more of a caramel color.
The football players have dark skin.
No one will care if there's a lot of other dark skinned people in the games. You're really blowing this out of proportion. However, if they made every dark skinned person a part of the evil team, I could see some complaining.
