They are kind of an exception, seeing how they are BOTH clones of Peter.

Ben became the 'Scarlet Spider' after discovering he was a clone, while Kaine... well, died. and then came back, then died again, then came back as a Gaint Tarantula.

Then eventually took on the Mantle of the Scarlet Spider.



So yeah, they kind of have their own stuff going on, and Kain was either dead or Crazy for most of it. XD
