I think it is reasonable to assume Raiden won’t be in COTW but it’s def not impossible. The OG MOTW had Dong appearing in Jae Hoon’s background when he’s not being played. Then you have SF4’s airport stage where Boxer pops up from a plane, & if Boxer is being played, Claw appears. (I forgot what happens if Boxer is fighting Claw in the stage tho). There’s also Guile appearing in his SF6 stage when he’s not being played.
Tizoc stage will double for Big Bear, and Dinosaur will be in the background for Big Bear but they will never have that epic tag match of babyface and heel unfortunately
Most SNK grapplers have supers ripped straight from Kinnikuman. Even Tekken's King's new Rage Art is a homage to Kinnikuman. Many devs seem to love that manga/anime.
Raiden is Big Bear's Heel persona, so what if Big Bear is in the game, and when you play him on this stage King of Dinosaurs is in the background commentating. That'd be cool.
Was Tizoc's stand C chargeable in the original beta? Or is it just a slow move that grants a juggle on air hit regardless? They seem to be giving Tizoc a lot of combo creativity outside of rev accel stuff which is always welcome. One more thing the posideon wave special was on counter hit, not wild punish, but I wouldn't be surprised if wild punish posideon wave also granted a huge combo on hit
