(posted in the order I created them)
I made these using the MMZ3 portraits' palettes (why is Phantom there if he died in MMZ1, you ask? Shhhh, don't worry about it) at Twitch emote resolution (28×28), which proved an interesting challenge, but I think they turned out pretty good! There's probably room for improvement (especially with Fefnir, and maybe also Harpuia?), but all in all I'm proud of the end results.
(Edit: Made a few changes to Fefnir, Harpuia, AND Leviathan)
It's just BTTV, but it's nice having actual custom emotes and not just ripped sprites and memes
