I am just asking, are there any other DC alien species which exist in this story ? Like Thanagarians, Daxamites, Tamaraneans, Martians, etc. Well you even make false Marvel planet into real planet like Yttrium and its habitants Yttriumites just like Hyperion. I mean instead of Coluans you should make Brainiac as the A.I. of Krypton same as from DCAU due to you had not shown Krypton's situation before its destruction.
