Untangling Xehanort

BUR #47796 has been approved by @evazion.

rename xehanort -> young_xehanort
create implication young_xehanort -> xehanort_(kingdom_hearts)
create implication master_xehanort -> xehanort_(kingdom_hearts)
create implication terra-xehanort -> xehanort_(kingdom_hearts)

Xehanort is a complicated character to tag, as he has five different personas, all of whom are distinct characters. These include:

• Master Xehanort, who is an old man. Often seen as the "main" persona due to being the Big Bad of the whole series.
• Young Xehanort, his teenage self, introduced in Dream Drop Distance.
• Terra-Xehanort, which is Terra possessed by Xehanort.
• Ansem, Seeker of Darkness, Terra-Xehanort's Heartless, and the main antagonist of Kingdom Hearts I.
• Xemnas, Terra-Xehanort's Nobody, and the main antagonist of Kingdom Hearts II.

For some reason, the tag "xehanort" is used only for Young Xehanort, despite him being the last of the five to be introduced. I can't speak for all KH fans, but when I hear the name "Xehanort," I think of the old man. At first I considered having master_xehanort be implied by the other incarnations, but after giving it some thought, it would probably be best to have an umbrella tag.

I'm not including Ansem and Xemnas in this, as from what I can tell, other Nobodies don't imply their counterparts, and I assume the same logic applies for Heartless.

Also, in case anyone asks, the reason I'm renaming the tag to young_xehanort instead of xehanort_(young) is because that's how he's referred to in-game.

If Terra-Xehanort looks like a Terra shouldn't he imply Terra, if anything? idk shit abt kingdom hearts i havent gotten around to playing it

In Kingdom Hearts everyone is everyone else, and on Danbooru none of them imply each other.

Each form of Xehanort is basically an independent character with all the time travel shenanigans. I did think it was hilarious that Xehanort was being used for Young Xehanort though. (personally unqualified "Xehanort" makes me think Terranort's science getup).

I don't care if there's an umbrella tag, but I figured Danbooru was avoiding any implications with Kingdom Hearts to prevent a nightmare.

rename xehanort -> young_xehanort

Alternate BUR. I'm personally in favor of an umbrella tag, but I'm including this as an option in case anyone is against it.

I'll do this for now because they look similar, but I'm afraid this is going to open a whole can of worms.

BUR #50104 has been approved by @evazion.

rename eraqus -> young_eraqus
create implication young_eraqus -> eraqus_(kingdom_hearts)
create implication master_eraqus -> eraqus_(kingdom_hearts)

This may be opening the aforementioned can of worms, but Eraqus should probably be untangled as well. Currently, the chartags used for him are Eraqus for his younger self and Master Eraqus for his older self. This is the same as how Xehanort's young and old selves were tagged prior to BUR #47796 being approved, so for consistency's sake, I've made a similar BUR for Eraqus.
