Ohana the helpful bot has plenty of commands, mostly for anime and manga servers. With Ohana you can search for anime and manga, link your MyAnimeList and AniList profiles, and many other things. Ohana mostly focuses on integrating MyAnimeList and AniList, allowing you to view information from each website using simple commands.

• Commands such as .anime searches for the anime your provide (on MyAnimeList) and and returns a set of search results from which you can choose the anime you're looking for. Same thing goes for .manga command.
• Besides that, you can link your MAL using .linkmal in order to easily access your profile and stats later on. Same goes for .linkal (AniList). If you've linked your MAL you will see your own stats for any anime/manga you search for along with its info. 
• You can request any MAL or AL profile using .mal or .al followed by nothing if you've linked your username, followed by a username, or followed by someone's @ if they've linked their username. The profile returned will be presented in a nice navigatable embed.
• Besides all that, Ohana offers a set of fun, utility and moderation commands, plus a list of admin commands that help customize Ohana to your liking.
