BotW Bokoblins by MisterMike
Perfect for a custom enemy! Or, if you really want to, you can have your protagonist be a Bokoblin (yes, it looks good in CSet6), though there aren't any BS or Z3 tiles.
I did not make these tiles. They were drawn by MisterMike on the VGResource. Consent was given to submit these tiles to PureZC. All I did was rip and arrange them to be compatible with ZC.
