For my first Gas post, i bring you the famous Menacing (ゴゴゴゴ) effect,
made famous in the recent years by the anime adaptation of JoJo's Bizarre Adventure.
There are 2 versions of this gas: A purple colored one and a black and white colored one. If you want to have a color close to the anime adaptation or be a ''read the mango'' kind of guy, i got you covered. Theres also a two character and a single character version for both of them (they seem to have quite jagged edges in the imgur previews but they look fine in game).
