Batman (Dick Grayson) and Robin (Damian Wayne)
If you didn't know, things are different in the Batman comics right now. It's... complicated. See, after a fight with Darkseid, Bruce Wayne was presumed dead, however he was just stuck time-jumping in the past. Meanwhile Dick Grayson (the original Robin, but more recently, the solo hero Nightwing) assumed the mantle of Batman and took Damian (The son of Bruce Wayne and Ra's Al Ghul's daughter Talia, the latter secretly raising him up to be an assassin and an arrogant brat) under his wing as the new Robin. Tim Drake, the third Robin, took a new identity as Red Robin and asserted that Bruce was still alive. Indeed, Bruce Wayne eventually returned to the present day and is alive and well, having re-assumed the Batman cowl. Dick Grayson however, under Bruce's blessing, has stayed on as Batman also, as Bruce (having publicly announced himself as the man funding Batman all these years) carries out his new Batman, Inc. initiative which seeks to deputize other heroes around the world in a 'Batman and Robin style mold', carrying out justice in their own parts of the world and working within Bruce's network.
I told you it was complicated :)
