OK, this is hot. Gorgeous artwork showing a petite Asian girl transforming into a strapping, muscular, amazon robot fighting hottie.
This really has everything you expect to see in a female muscle growth or giantess growth comic. First off we have the juxtaposition of the first and second panels, which show a total role reversal – in the first panel Kinniku is smaller and below the robot, but in the final panel she’s grown tall and powerful, and is now occupying the superior position. The intermediary panels show the transformation occurring, with her clothing first tightening over her growing body, then beginning to tear as it suggests the extent of the transformation (in this case her large, bulging biceps protruding from what had previously been her slender arm. Finally the clothing bursts almost entirely, revealing the final result and teasing for a better view in the final panel.
