Agreed that Metamorpho likely wasn't a last-minute addition. In addition to what Psypher mentioned, Deathstroke's reaction suggests it's the first time he's encountered Metamorpho.

I would hope they do get into Metamorpho's backstory a bit in the second half of the season. And it would be nice to see Katanna get some lines and learn more about what backstory she shares with Lady Shiva.
