Sadly I pulled both sketch variants. The figures are hard to tell apart at a glance, and Hydroman looks poor in particular (no translucent effects, which really serve to differentiate him from Sandman). And ClixFX bases are normal. I'm guessing they either didn't think to do sketch colors there or decided it would be too much of a headache.

It is sad to see the nicely painted foam on the crashing wave of Hydroman's ClixFX base next to the b&w color scheme on the figure.

(At least my Kraven Prime wasn't sketch variant. Given how rare SR primes are I'd have gone ballistic.)
