Yeah, they don't need to show them in the trailer or the opening. What we saw in the trailer is probably the first half of the volume so Adam is most likely going to be the trump card at the end during the final fight against Cinder & Co. and the White Fang (Adam and the two members next to Roman in the WF mecha introduction).
