The sprites? My friends did.
If you're wondering if they were stolen, no they weren't. I'm Kradakor
Hot damn, yo! Those sprites are killer, dude.
Edit:
Here are some modest recolors I did.
Nothing Spectacular.
Just an upgraded Alucard Wolf Form with a more common brown coloration and the harness and sword completely separated from the rest of the palette.
Next are some variants for the RoB Axe Armor based on other versions.
Going clockwise from the upper left, original axe armor, the weak green axe armor from SotN, the red axe armor from CVDX, and the axe armor from SCV4.
And the last two are SotN Axe Armor recolors based on the Red Axe Armor and Antique Axe Armor respectively.
The red one is based on CVDX again and the antique is based on SCV4 and I gave it a 'Golden Axe' just cause I'm a silly bastard.
