#3 Rebuilt himself - R Truth

Carmella's pairing with R Truth resulted in the revival of Truth, as the latter had been lost in the mix on RAW. A move to SD Live and the idea of Truth TV made R Truth relevant on Tuesday nights.
In fact, Truth TV featured all the 3 McMahons on the SmackDown 1000 episode. R Truth even once main evented SmackDown Live against The Miz, and is a regular feature on WWE TV. His ever increasing popularity may lead him to a future title reign or involvement in the title picture.

Nonetheless, the dance breaks and Truth's MMC matches have been entertaining for the WWE Universe, which has helped him rebuild his character.
