This may seem petty, but I was looking at what has already been nominated for MCU and noticed that there is Bucky Barnes/Okoye (MCU), Bucky Barnes/Sam Wilson (MCU), and Bucky Barnes/Sam Wilson & Steve Rogers (MCU), whilst there are five other pairings with Bucky's name written as 'James "Bucky" Barnes', which is how it is written in the usual AO3 tags.

Personally, I think that a) it would better if they all matched, and b) that the usual AO3 tag way would be the preferred way to write Bucky's name, but maybe that's just me. All I know is that when I was checking, I nearly missed some of the noms by looking under one version of the name and not the other *shrugs* Just a thought :)
