I created this custom toy last year [2016], but I never uploaded it anywhere, until today.
I fused the Combiner Wars / Titans Return Hardhead toy [for his lower body / legs] with the Fall of Cybertron Shockwave [for his upper body]. Hence I made his new legs sturdier. The winged backpack came from Transformers Prime Voyager Ultra Magnus and the arm-blasters came from the Combiner Wars Thundercracker, and some Gundam model fodder [used for the two cannons that are pointing upwards on his backpack]. He still can transform, but he doesn't look so cool in his "cyber-tanky form", per his new legs, which were formerly jet parts.
I made a corresponding good guy... or more accurately, a good girl, to be his opponent. That customized fembot is StrongArm, from the TF Robots in Disguise Cartoon. I'll upload that custom as well, next. More pics of Shockwave are shown in my DSNG blog, just search for it.
