Pulsar and Tempest are both members of Strike Force Alpha. One of them is big and yellow, and one of them is blue and white... but it's not clear which is which.

Pulsar and Tempest saw to the defense of Iacon under Optimus Prime. And There Shall Come...a Leader!

Note: The placement of the text balloons weakly seem to imply that Big Yellow is Pulsar, as does Optimus reminding him to provide covering fire for gunners (the blue and white robot was down among the gunners) but there is no real way to say firmly which is which.
