User blog comment:Erebus Elysium/Ideas for pages that need clarifying.../@comment-24667521-20140704011827

I think the children of Loki thing would belong under Avengers AU, since that AU kinda covers every possible universe that could relate to the Avnegers in RotBTD. If we make an EU for them then that might cause a whole bunch of pages to pop up for every single possible EU that relates to the Avangers, and like you said, it would get out of control. I think Avengers AU kinda covers all that.

As for fan-charcaters, I pretty much agree with what TreepeltA113 said. If it's just an AU version of an existing character, then I am ok with that, since many of them would just fit under an AU that we already have. (Genderbend AU, Dark AU, etc.) But if it's just can rafter made form scratch, then they probably don't belong here. They're not canon and should be left on deviantART or other websites. Otherwise we will suddenly get a bunch of people posting their owne charcater and it might turn into a hectic competition where everyone is trying to get attention for their own OC. And we don't want that. :/
