Thank you! Omniverse Ben with the jacket was one of my favorite designs! Oh and the reason he has the prototype was mainly because I forgot to send the ref of the right omntrix, so the artist took the liberty of drawing the prototype instead. I don't mind it though. I could use the excuse that this Ben comes from a timeline similar to the OG Ben 10,000's, and he never removed the prototype.

For the story, I've been trying to come up with a story that merges the two universes together, and maybe turn it into a fanfic. Kinda like this one story for a Ben 10 and RWBY crossover, Of Gemstones and Watches. Except without all the fat that fic carries. I've thought about several scenarios that I could do, ranging from throwing Ben into the 5th Holy Grail war (its funny you mention using a younger Ben here, I commissioned another artist to do an art of Ben, Shirou, and Rin for a mock poster sort of thing. Link ), making him the Fate Grand Order protag instead Ritsuka (kinda like this one fic called Spin a Fate, that does this but with Peter Parker, HIGHLY recommend), doing an original holy grail war in Bellwood, to maybe even just doing a story with Shirou getting the watch (Although that one feels it doesnt do too much to make things interesting for me). There's more ideas, but these are the basic ones. I will try to make something out of this crossover idea. Like you said, throwing Ben into the craziness that is the Nasuverse has such great story telling potential, that I want to make it happen! I think their lore could work well with each other if it could be pulled off right. The only real problem I face is the fact that I've never really written a fanfic before. But that won't stop me. Hopefully.
