Mr. Terrific
Well as much as I'm hoping Mattel makes an official version I'm not that patient, and I wanted something to do, so here he is. He is basically parts box bits cobbled together, the only real work was fitting the jacket and shaving down the inside of the arms.
Recipe:
Head: JLU Superman
Torso and Legs: 9 POA Flash
Arms: TNBA Bruce Wayne
Jacket: X-Men Movie Professor X
