BATMAN IS GETTING A CAMEO IN SUICIDE SQUAD
Was there ever any doubt of this happening. With most of the key members of the Suicide Squad knowing batman as there enemy he will be seen. Now DC has been very secretive on how he will be seen it will go 1 or 2 ways.
1. He will be seen handing the Suicide Squad members over to Argo.
2. Defeating them at the end if they go rouge.
3. A flash back of how they got defeated by the Batman.
4. Or warning Argo of what they can do.
With this DC will not confirm which option it will be but we know it is one of them. But we know that Batman will be involved and will appear [even if it is in a small mention].
