Here is a small animation test I did with Toon Boom Harmony ! I chose to animate an old video game boss idea of mine, which I named Tropy Khan, and for whom I already imagined basic pattern ideas. Ideally, he would be fought from a wooden boardwalk, upon the lake he dwells in, as the boss of a jungle world. Tropy Khan would permanently move towards the protagonist, continuously destroying the boardwalk, as a scrolling forces the player to move permanently. His eyes would be his weak points.
The construction of the rig and the animation process took me around ten days.
