Zombies Runners in Zombicide are always a scary proposition because they get to activate twice in a Turn. Toxic Runners are even more scary because if killed in melee combat they explode and their Toxic Spray causes one Wound to their assailant. Here are the first eight of my 16 Toxic Runners.
There is a great sense of movement in the way these figures have been sculpted and you can tell at a glance that they are Runners and not Walkers. I like them.
