Team-up You'd Most Like To See
Well, first I'd just like to put it out there that Damian teaming up with anyone is pretty much comedy gold. So just... I would genuinely read a book called Damian Insultes The DCU (And Then He Gets Beat Up). Damian having a stupid crush on Cass! Jason treating Damian like the little brother he never had (or really wanted)! Damian being utterly mystified that Oracle even lets Misfit out of the house! Rose Wilson treating Damian like a little brother WHILE he has a stupid crush on her! BEST BEST BEST.
And, y'know, I have a soft spot in my heart for Oracle & Red Hood teaming up to take down the Joker. ANGRY GROWN-UP BATKIDS WITH JOKER ISSUES ARE MY FAVOURITE. On that note, I also NEED NEED NEED some form of Steph & Jason interaction. Especially now, given that his reaction to death-and-return was to try and kill Batman and hers was to start wearing the bat. I just. They have both been alive at the same time for YEARS now, DC, get on this! Actually as much fun as the others would be, and as many more as I could probably think of if I kept going, I think these two are the real answer to this question. Given that they are kind of an OTP and they have never even met. Batman thinks they are the same! The ways that this is and is not true fascinate me endlessly because I am a weirdo.
If I keep going on about this I will get blathery and it will be past midnight and then I will feel like I failed to post this today, so I am instead going to link to the recently-reopened
Even Robins site which has lots of clever things to say about Steph and Jason, both alone and in the meta ways they are connected despite never having a single team-up, seriously DC what is that about?
