4: Shazam Family
This one is probably going to be more tricky to get back on the page than the others on this list, due to the fact the one that brings them together doesn't even have his own comic. The main reason why I like this team so much is the fact if the Justice League were to up and vanish THESE GUYS and Shazam would have things covered We have a speedster (Darla), a Power House to fill Superman's role(Pedro), a tech. expert(Eugene), an equally powered woman to hold the team together (Mary), WE EVEN HAVE OUR EGO MANIAC! (Freddy) As I said the main reason why I'm sure they haven't been used is because they really can't be used without Shazam having his own book. If Shazam wasn't in God form at the moment, I would have loved to see the six members of the Shazam family flying at the Anti-Monitor forces.
3: Ted Kord
Remember the end of Forever Evil? Remember how Lex Luthor was actually a decent human being and let Ted keep Kord Industries? Then you should also remember the reason WHY Lex let him keep it. According to Lex, Ted is extremely talented in creating technology, especially in robots the size of insects. This is the gateway for Ted Kord to become the new Blue Beetle! After Ted and Booster's run with one another in the Justice League 3000 series, people might be intrigued to see what adventures a modern version of the character could go on. The only problem is that the current setting of the world (i.e. Darkseid War) would tear apart a character like Ted. It's pretty obvious any 'vigilante' leveled heroes would be torn apart during the midst of the battle between Darkseid and Anti-monitor. That should have been made obvious when they turned Batman into the God of Knowledge and sent him on his little search for the truth. Maybe post war, when the Justice League will need some backup for future missions, he will show up in the Bug and be a hero again.
2: Plastic Man
After reading the Injustice Year Four annual, it reminded me how important Plastic Man is as a character. This is a man who has grown up as a bad guy and now tries to make it up now with acts of heroism. In the annual, he isn't part of either side of this war. He knows what Superman is doing is wrong, but all he wants is to get his son back to safety. If anything, this makes him the most human out of most characters with powers in the DC universe...so why not have him? DC claims they want to tell good stories and you have a character that can be played both dramatically and comedic. "But isn't he dead?" You are probably asking yourself, to which I respond, "how many times has the joker come back?" Or "how do you know those chemicals aren't transformative? It's Gotham after all!
