Implicating toriel → undertale
Link to implication

Reason:

Character from the game. Since it's such an uncommon name, I don't see any need to disambiguate it. Nor should it be aliased to the full name, since that's spoilery.

There's actually been couple of posts that have forgot the undertale tag, so I suppose this implication could be useful. Such as post #619252, which went six months without the tag.

Maybe also implicate some of the more popular characters from post #732094. It's got most of the cast tagged.

+1 for this, a pretty obvious one

Approved

Edit: Based on Genjar's suggestion, I took a look at the characters on that post. They should be pretty straight-forward to implicate but I'll list them here first just in case:

Easy ones:

• flowey_the_flower 71
• mettaton 52
• papyrus_(undertale) 131
• sans_(undertale) 157
• temmie_(undertale) 60
• undyne 164

Probably:

• final froggit 1
• froggit 3
• loox 2
• madjick 1
• moldbygg 1
• moldsmal 2
• napstablook 19

Unsure:

• astigmatism 4
• doggo 35 - Seems like an obvious furry character name
• greater dog 12
• lesser dog 17
• ice cap 1
• mad dummy 2
• monster kid 29

Few more that are missing from that post:
alphys 108
shyren 16
asriel_dreemurr 215
asgore_dreemurr 39 - Dunno why it's not tagged simply as Asgore. But since both tags are in use, it should be aliased.

If we're implicating (most, if not all) Undertale characters, we may as well also hit the amalgamates.
