%% The info on the names of minor characters was taken from Wikipedia. Therefore, it should not be taken too seriously. Hopefully later episodes will give the true names.
%% In regards to MeaningfulNames and CompositeCharacters: Pretty much everyone on this show falls under one or both of these tropes and to list the tropes under their character entries would be too redundant. Therefore entries to these tropes will only be listed on the main page and left out of the character page.

Due to page length, this page has been split into the following:
