Those stages are flippin' gorgeous!
The turtles' lair, the Technodrome and even a wild west town? Heck, even the Rabbids get their own stage (which is based on Rabbids Go Home).
I must say that this game is tempting me a lot more now...
That said, I realized why Utrominator is used to replace Krang. the Utrominator's robot suit matches the gritty aspect of TMNT: Smash Up. Krang's robot suit, which looks like a grown man wearing briefs? Not so much.
However, Bebop and Rocksteady will fit in a lot more easily, since they are punks (with the latter wearing army clothes, no less). They look tough without looking silly (although they're not too bright
).
Oh man, oh man! I cannot wait for this game. My guess on the remaining 7 characters:
1. Leatherhead
2. Bebop
3. Rocksteady
4. Hun
5. Baxter
6. Some Triceraton
7. Usagi or a Rabbid (depending on if the rabbids are considered secret characters that don't apply to that list; oh, and I'm still betting that the rabbids are just a single character with alternate costumes)
I'm hoping for Bebop and Rocksteady to show up, since they never got a chance to be playable in a TMNT fighting game.
As for Baxter...I am not sure which version they'll use. The fly version could provide some variety, though.
I was thinking that Tatsu could show up, but sadly, he doesn't really have anything to stand out from the others.
Although the triceraton is a good enough suggestion to me, so that'll make a nice compromise.
Now, as for Usagi...this could be complicated, as he is a character that belongs to Stan Sakai. There would have to be some sort of rights negociation for him to make it in.
Note: the last two images aren't working for me.
