Yay for sketch dumps! This one isn't as big as some others that I've done, but that's okay.
Bart Allen (Impulse), his mom (Meloni Thawne), and Thaddeus Thawne (Inertia). The boys are set to about sixteen or so.
The bit there with "Extracirrucular activities" is a visual musing over what sort of activities the boys would be into if they were just ordinary guys. For Bart, I went with track and field, since I doubt there's a video gaming club. For Thad, I figured he would go for debate team or mock trial or anything that allowed him to verbally and intellectually spank his opponents and look good doing it.
Bart, Meloni, and Thad are all property of DC.
