Yep it must have been Combiner Wars. Show was horrible from what I've heard, and the comic tie ins were clearly forced. But the toyline was great. We finally got the updates to the classic Scramble City style combiners we'd been wanting. Funny most of the Stunticons are new guys in RID, in Combiner Wars Wildrider got replaced by Offroad the pickup truck and Blackjack got added for the chestplate. Also funny since Bee was utterly absent in Combiner Wars and we got two Optimus torsos and a ton of the G1 Cast as limbs.
