They glowed in the dark, and so did their discs (and the Warrior’s staff). The discs could be attached to the figures’ backs as well. The line was poorly articulated and sold poorly.
The light cycles were pretty cool. The figures fit inside, and there was a ripcord you inserted into the back of the cycle and yanked. I’ll post them both (yellow and red/orange) separately.
UPDATE (10/21/14): I found another set of carded figures at various price points. See below.
