Umm...sorry to spoil this for you, but that ain't Thunderball.
Morgana replaced him on the Wrecking Crew with her own agent. The how and why was....fuzzy, so much so that Thunderball didn't appear in the next Wrecking Crew smack down.
Though for an intelligent Thunderball, might I recommend 'Robin's Revenge'? Thunderball was depowered at the time, but still managed to have a big influence on the plot as a whole.
