Alot of characters like Tim Drake on Batman 457 get First App as a character like First Robin. So on Justice League 21 how come no one added some of the characters like Pedro as first all in Shazam family?
Well Pedro's 1st Appearance was actually in Justice League (Vol 2) #8 in the Shazam Backup Story. In the Shazam Backup Story the main character that made their 1st Appearance in Justice League (Vol 2) #21 was Mister Mind. I hope that answers your question.
I will try and talk slow this time so u get it. I understand Pablos character first app is Justice League 8. Tech its Flashpoint 1 same character same name. But i understand different timeline blah blah JL 8 is his first in prime earth. Now, my question to do u was if u look at batma 457, it says Tim drake first app as Robin for example. Not Tim drake first app, this is as Robin. Same thing happens in Justice League 21. Pablo turns into a Shazam Family Member with powers. So im saying how come no one has added that. Its the same thing as tim drake turning into robin, if u guys wrote that then u need to write this also.
It's a good question and I do understand were your coming from. I took a look around at some of the other Post FlashPoint/New 52 Issues and it seems this certain 1st Appearance for the character and the characters hero or villain appearance doesn't seem to be done on any Post FlashPoint/New 52 Issues. Only Pre FlashPoint DC Comics Issues seem to be doing this certain thing. I would recommend ask one of the DC Database Staff Members why this is the case they would be the best people to give you an answer as to why this is the case.
