Well, I'm surprised to see pictures so early, so in any case, my thoughts in general.
Nex:
Well, I hope the colours are rearranged at some point, though out of all the small scale heroes this one has the most continuity with the original white/orange colour scheme, though by now I'm used to the silver so I just don't know what to think.
Stringer:
Now this guy looks cool. His colour scheme needs to be revised a bit (why the blue?) but overall I think he looks great.
Bulk:
Errrrrmmmmm...what to say about this guy. Well, I dunno really. At least he's bulky for once, though that's kinda blown out the water with Stormer XL. If I'm honest, I don't know what exactly he is. It's too poor quality and the design seems cluttered...
XT4:
...that is until I saw this guy...I have absolutely nothing to say here.
Core Hunter:
This is cool, definitely. The mix of red and black is never bad, and those spikes, that armour, it's like a mix of all the big villains we've had like Black Phantom and Witch Doctor in canister (well, mid-bag) size, but like 2x the awesome. This guy will rock your megabloks!
Voltix:
Very much a U-turn from the awesomeness that is Core Hunter, this guy just looks dum and cluttered. Why does he use the Black Phantom mask? Why is his colour scheme so wrong? It just looks plain bad...
Stormer XL:
This is where I get undecisive. I'm happy that we get a hero with a NORMAL colour scheme (looks at Voltix) and I love some of the new pieces, but some things bother me. His size is just ridiculous, so I'm hoping that there's a smaller scale Stormer. His arms look very cluttered with those wing accesory pieces, and finally, what is up with his legs? They look awful compared to the Rocka XL design, with the hollowness on one side and thin-ness on the other.
Favourite Set: Core Hunter
Very much looking forward to this guy.
Least Favourite Set: Voltix
Ugh...just...ugggghhhhh...
