I created this illustration completely in AI CS1. I like robots and I love the illustrations that were on the box packaging of these awesome old giant robot toys. Below is a brief about giant robots and some wikipedia links.
Super Robot (スーパーロボット Sūpā Robotto?) is a term used in manga and anime to describe a giant robot or mecha, with an arsenal of fantastic super-powered weapons, are extremely resistant to damage unless the plot calls for it, sometimes transformable or combined from two or more robots and/or vehicles usually piloted by young, daring heroes, and often shrouded by mystical or legendary origins. This is distinct from a Real Robot, which is a mecha portrayed as a relatively common item, used by military organizations in the same manner as tanks or aircraft.
