"This is Lan the Fire Imp from Introspurt's Crimson Keep, published on Newgrounds, first debuted in Chapter 1 of the series.

The original character design is made by Introspurt.

The pixelation is made by a Discord user named Z9YE.

The one above is my recreation on Terraria, built in-game and seen on minimap, and shared on DeviantArt, Newgrounds and r/Terraria."
