Let's see what they're mashups of. The white one is Stormer 2.0 with Stormer 3.0's weapon and Surge 2.0's gun. He also has Stormer 4.0's drone thingies. The silver one is Nex 2.0 in a recolor with Stringer 3.0's claw. The green one is a mashup of Breez 2.0 and 4.0, with Nex 4.0's weapon. The yellow one (I got to see this one) Is Evo 2.0 with Stringer 4.0's armor clip-ons. The red one is Furno 2.0 with Nex 3.0's claw and Stormer 4.0's drone thingies. The blue one is Surge 2.0 with Breez 4.0's swords.
They all have 1.0 Hero Cores (I can't remember how they attach on, unfortunately), and they all have glatorian heads. They modified the 2.0 helmets and headgear to fit them.
All the parts are dull colors, not shiny and reflective like Lego.
And when I was there, they were on sale; 2 for $5. I didn't get any, though.
