Yep, Spider-Man recently teamed up with his old enemy, Rhino, but not Peter Parker. It was in fact Miles Morales who featured in this pairing.
Aleksei Sytsevich, better known as the Rhino, has greatly evolved since debuting in 1966. At first he was just that dumb henchman in a silly rhino costume. Then at one point he became smart - sort of like when Homer Simpson removed that crayon from his brain. However he quickly grew bored of not breaking stuff. After that, he actually got married, and then he returned to crime because comics need to return to the status quo.
However, in Miles Morales: Spider-Man #2, the titular Spider came across the Rhino whilst on a missing persons case. Miles was surprised to discover that Sytsevich wasn't the perpetrator, but was on a little missing persons case of his own. The pair even ended up teaming up for a short while.
It's a strange partnership to say the least, but it was good to see Rhino continuing to develop beyond hired muscle, and it would be great to see Miles go on more little adventures with unexpected allies.
