But then kids wouldn't' associate Furno with fire. Give a random kid, show him Vakama and ask him what element Vakama controls; they'll almost definitely say fire. Show him Nuju, he'll say ice. Even though they have identical builds, their colour tells them apart. The same principle applies to Hero Factory, even though they have no elemental powers.
I think it's silly how the brains mutated all the creatures, but didn't mutate Surge. As he's being made into a set, they probably didn't want it having around 2 minutes of airtime.
OK, Webs's 1.0 colour scheme I like. The light blue cores and heads on Webs and Shocked spoil them IMO. Gunmetal core/head for Webs and a invert of the blues on Shocker? The light purple works on 1.0, not 2.0.
Good Day!
