Please, stop changing Black Widow's last name in the appearances list from Romanova to Romanoff.
Like I explained every single time I undid edits like that, the recap pages of Black Widow Vol 5 refer to her as "Natasha Romanova," meaning that Marvel wants her to be called "Romanova" instead of "Romanoff."
Before we start getting into an edit war on the avengers page i figured it would probably be better to share our opinions and come to a consensus. Personally i don't think the particular characters in question should be put in the main team category because they're not part of the main avengers series line-up. They seem to have more of an "on-call" status and don't show up with any of the teams regularly, so i thought they should be put in their own category.
How are Polaris and Havok 'Utopians'? I wasn't sure if they even picked a side, but I thought they both went to X-Factor. Or are going to. Either way, if anything, they'd be on Wolverine's side, right..?
Please be more careful where you add X-Men appearances. Just because two members are there doesn't mean the team is there, just like Thor and Captain America showing up doesn't mean the Avengers are there. It's about the context of them being there and whether they're actively part of the team at the time.
