I created a set of characters for the board game Rumblebots for the Italian company DV Games. It was quite a challenging task as it required considering many different aspects, such as the type of robots, their level, attack strength, type of critical attack (which could be acid, spikes, electricity, exploding weapons, precision weapons, gas, etc.), ability, defense level, pose, and character color.
The first characters belong to the bio group. Bio robots have strong connections with the elements of nature, which may be reflected in how they are built or power themselves. The design of these characters should contain a green color.
Some characters belong to two groups at once, for example, bio and animal (hence the colors green and pink) or bio and steam (green and rusty).
Each character took me about 8 hours of work, including searching for sketches, line work, color selection, and rendering.
