The original reasoning for the alias was that Flash Sentry was a EG character only who was, as stated by the creator of MLP, never going to be included in the TV show.
Turns out, she's a lying liar who lies.
Flash Sentry appeared not once, but twice, once even speaking in season 4 of the tv show.
Therefor, he is now able to be tagged separately in pony and human forms and the alias is no longer valid.

The sunset shimmer alias is still good thankfully, she hasn't made her way into the show yet.

Done

Now we just have to handle the clean up.
This will take a while, and suck pretty horribly.

If anyone wants to help, I'd certainly appreciate it.

Same rules as other ponies, Equestria Girls style human form keeps the *_(eg).
Anything else gets the *_(mlp) tag.

Edit: Never mind, less of them than I thought.
Tags cleaned up.

Edit2: Why isn't strikeout working?

Edit3: Ah, right then.

As an ex-admin/dev said once: "Strikeout is a single line effect"

Works multiline for me...

It only stops workingif you add a blank row.

But
multiline
is
fine.
