As much as I don't agree with you I can still understand some of your reasoning. I get that they don't really fit the feel of Mizhar, I get the assumption that they're mostly used by adolescent players, and the copy write infringement stuff. I mostly just don't understand the I can't picture what they might look like if they were real, I'm pretty sure everyone in Mizahar isn't supposed to look like a fashion model with modern day clothing.
I just want to point out that anime has multiple genres..and a lot of them don't have dragon ball z powers or any powers at all. Some do have giant robots mind you >__>..but the people that pilot them are normal. There are highschool dramas, romance, period pieces, even studio ghibli did a movie about world war 2 and Not all anime's have the same art style..even if it sure as hell seems that way sometimes.
Here are some honourable mentions.
