These are 2-d front-view 'battler' monsters that I commissioned for my game Nighthawking 2, which has kind of shifted scope and might not use this style after all. This art was done under commission by Teo/Saorlaith, @mnaago on Twitter.

The fightable enemies in this game were intended to be a mix of skeletons and ghosts, nocturnal wild animals, and different kinds of mimics, some with a 'medical equipment' theme. Many of these were made to match up with sprites from the Dawnhack set, which I intended to use as the overworld art like in Nighthawking 1.

There are 24 sprites in total:
Angry crow
Angry goose
Brain jar
Candle knight
Cerby
Ghost
Hellhound
Kraken tentacle
Kraken
Lich p (phylactery)
Lich
Mimic bpc (blood pressure cuff)
Mimic chest
Mimic door
Mimic iron lung
Mimic spellbook
Owl
Reaper
Robe boy
Skeleton default
Skeleton fire
Skeleton shield (green)
Skeleton sword (gray)
Stray dog

All of the .png files should have alpha-channel transparency. I originally requested (and have included here) the raw .sai files as well, so that color edits can be made relatively easily.
