[GrimZata]

Durian was confirmed as a different Rider, one of the confusions came from the fact that a picture showed Gridon with two silhouettes underneath him, that were representing the Pinecone and Durian Arms, and everyone jumped to the conclusion they were other forms of Gridon. However the image actually referred to them as "Other Riders" plural, so they were all different Riders, and Kurokage was confirmed as the name of the Pinecone one.

Although I honestly didn't think we'd see the durian guy this soon. I wonder if he's Team Mouryu or Spingere's Rider? His lockseed and the silhouette of him from Telebi(I think that's where it was from.) were both green, and so are Mouryu and Spingere's logos.
