This took way too long for me to make, I've made the Death Egg Robot a few times in the past but this time I used a new technique to make it more durable and hopefully make it easier to make in the future. Several parts were made in my 3D printer, the feet, shins, thighs, and hands (basically all the complicated parts that give me a hard time fabricating) While I used craft foam and foam board to make the backpack and face since those parts need to be light and soft, and everything else it cobbled together from things like candy balls, a cheap yo-yo, a Kool-aide container, some plastic shot glasses, and half a pokeball. All the articulation is made from ball joints you'd normally find in Lego Bionicle and Hero Factory sets.
