Misskey is a Japanese twitter-like. It’s actually older than mastodon and very popular in Japan specifically. They have custom emoji reactions under posts, they have animation and advanced markdown, they can have cat ears on their profile pictures, THEY HAVE QUOTE REPOST, chat, advanced search features, etc.

Misskey have been forked multiple times (foudkey, calckey, etc.) and those forks are more popular in English-speaking communities.
