The way Titans/Legion was plotted gave plenty of opportunities for the two (or three) Legionnaires who never used their powers to do so though.
They could have included Kinetix and Sensor in some of the other missions - thrashing Universo’s fleet or the first mission where they discovered the Titans in stasis.
Even in the crowd shots at the end versus Blackfire’s army.
Inexcusable in this instance, in my opinion. though of course you raise a good point that not every team member needs to appear in a crossover
Yeah, I was careful to make it a general point, as 1) I couldn't recall the details of the plot even though I managed to write giant posts about it and 2) I agree that there should have been scope to use each of them in all the side missions.
