Commissioned piece. This comes from the Old Republic era comics, and in the original iteration were frankly totally insane. There were Mandalorians riding these droid like vehicles in vacuum without a cockpit, and the original was something that looked like a trilobite meets an Opee from the prequels, with unusable limbs that seemed to be there just for show. Some of the art later got more functional looking, but still the idea seemed nuts to me. To impose some sort of order on the design and the concept, I figured it was basically a flying Robotech style mech/fighter.
The legs can either grab or walk, depending on the mode. There’s some precedent in my older stuff with the Zeta carry-all, and I figure this was an older attempt at a combat version of the same basic idea. Walker mode is basically to slide under shielding and overawe infantry, or offer some level of mobility in poor repulsorlift environments. Once under a shield, it can offer aircraft mobility via repulsorlift, though not starfighter performance. But in either mode, it offers nowhere near the efficiency of dedicated surface or flying vehicles. Perhaps marginally less crazy than the original design, and hopefully cooler looking.
