Where is Mona on that list
For your mother group, are you just listing characters but you're not going to include the whole group as traveling in all one big group right?
I'd think for any group, we should only have only a maximum of 5 characters per grouping together in the story. Ice Climbers would count as 1 person.
Like you can make a group like this:
-Master Chief
-Claus
-Ice Climbers
-Zelda
-Poo
And that should be good. But even 5 characters is pushing it. 4 seems to be a good number per group. If it gets too big per group each individual person cannot get to say much nor get "air time" to do things and they are simply like in the background not doing much.
I wouldn't want it if Master Chief does all the butt-kicking and smack talking in this group while Claus, Ice Climbers, Zelda, and Poo just sit there and say nothing and once in a great while hit someone in the story. A group needs all 5 to talk and all to participate and be on the screen looking cool and chewing bubble gum. Master Chief (or any other character) shouldn't get all the limelight.
Having small groups of at most 4 or 5 seems optimal to me, so that all characters who are represented get a fair amount of air time and people like Master Chief doesn't get like 90% of the representation and his other team members get like 10% all combined.
Otherwise we'd have trouble with a Ness/Flint interaction like that movie on Youtube
