Studio Series Thundercracker was excellent when the mold was used for Nitro Zeus and it still is. It is actually very effective as a seeker, especially if you open the wings. I also show him off in both modes with several others, including Megatron, Stinger, Brawl, Lockdown and Blackout, to name a few.
