What would you name these mythical weapons?

In case you didn't know, in the Spotlight event they gave us a preview of the next mythic skins and mythic weapons and they don't have names yet as far as I remember.

I name Widow's Mythic "The Black Widow", yes I know it sounds pretty generic coming from Widowmaker but I honestly wouldn't hate it if the name was "Black Widow" because it would be interesting

So how would you name those Mythic weapons?

And in case you don't know which hero

Season 15 - Widowmaker

Season 16 - Mercy

Season 17 - Reaper
