I think Odin has an Upper. I could also tell the blue Deathscyther had a Jerk in the lower quality pictures, but I didn't say anything
Although this set is my favorite so far. Just think, RB 5 might contain X2's, U2's, N2's, and Z2's. I've just noticed that every new RB contains the first 4 beys, the 2nd four, so I'd expect RB 5 to have the next four (likely skipping Yggdrasil). Who knows, they could do something completely different, but it's a nice thought. Wonder where they'll put Minoboros, Trident, and the "A" bey in, assuming December is Longinus and Gaia. January and February? Wonder if they'll get to RB 6 before dual layers are done. I mean metal masters ended with RB 6 killer beafowl, but I'll already be spending too much money
