Apparently these Steven and Wallace are evil versions from Altair/Sirius which I haven't played but whatever.
In any other game you would expect some crazy 12v6 with these 2 using the Sinnoh dragons competently but nope, they only use Dialga and Palkia which is kinda sad but understandable.
After that we are free to go to the next City (I should evolve Skarmory ASAP)
