The Flash Vol.2 #149
Wally West teams up with Barry Allen against Cobalt Blue and his Lightning Brigade, a group of Flashes who have fallen under the control of Cobalt Blue's gem. They battle and Cobalt Blue uses his flame to take away most of Barry and Wally's speed. They flee to the Flash Museum, where they use the last of their speed defeating the guard robots at the entrance. In the museum, they use Mirror Master's cloaking mirrors to hide until their speed returns.
