I see an incredible disconnect with him and the fans that will hurt him beyond repair. Look at all the people coming back/debuting, and who they're portraying. Jericho... well he's probably not being himself but it's not like he's a character. Rock, not a character. Brock, not a character. These guys are what WWE needs in 2012... I'm not talking about old stars, I'm talking about believable, real personas.
Tensai strikes me as someone right out of the 80s and early 90s. He's the odd man out and I don't think that's going to help him any. I think they need to humanize him through vignettes... give everyone a peek at what he's done in Japan, give a little insight into the character and who he's supposed to be, etc. They need to basically remove him from the direction he seems to be going in right now.
It's been a very long time since there has been a prominent Japanese character in the WWE(whether they were played by a legit Japanese person or not). If I'm missing someone between Yokozuna and Tensai... then I'm sorry but I just don't remember. Taka Michinoku is arguable in terms of a prominent character, and I think Taka lacked the same thing that Tensai does now in terms of getting the culture out there and breathing a little life into themselves through that. Yokozuna had Fuji, he portrayed a sumo wrestler, he liked to yell banzai and his finisher even had the word banzai in it, he waved the Japanese flag around, he had the girls in the kimonos/yukatas while Fuji and Yokozuna himself sometimes would wear Japanese robes... that's the kind of flavor I'm talking about, maybe not as over the top as Yokozuna but I think the culture thing would really help him.
