8 Best Friendships In DC Comics
2. Robin & Superboy
The newest friendship on this list, these two young heroes were only recently introduced to the DC universe (with this incarnation of Jonathan Kent only really being featured properly in the Rebirth banner) probably most famously appearing in Peter J. Tomasi's excellent Super Sons, and follow up maxi-series Adventures of the Super Sons, in which the two shared many, well... adventures.
While Damian Wayne has siblings in the form of the previous Robins, the son of the bat has also practically grown up with Jonathan making them, in essence, brothers and, as with most siblings, the two end up arguing a decent amount of the time, but also, as with most siblings, they're always friends again by the end of the day.
