I just constructed the last of Mixels Series 1 with the Electroids. Other than a pattern for some of the little hinged arms, I can also see a repeating cycle of character design as in there being a short Mixel, a tall one, and then an 'inbetweener' (middle height). Not a complaint; only an observation. Anywho, I'm not sure who to pick as my favorite this time around. I like Teslo already for namesake being named after a certain inventor just altered slightly, I have not seen that hose part in a long while which was great and having it 'hang' behind him as a tail makes him like some robotic version of Pikachu, and his overall form is nice. Now Zaptor is interesting but may appear a little too much on the 'mentally challenged' side. Ha. Finally Volectro is awesome and better in person honestly. That exclusive yellow bush is both cool and funny, his arms and fingers are very poseable, and the build was a fun one altogether really. It feels like a tie between Volectro and Teslo leaning a tad towards Volectro ....maybe. I don't know. Both were neato in my opinion. On a side note about the three tiny Nixels, those are not bad at all especially with everyone together. Only disadvantage is the ratio with three Nixels and nine Mixels. ....What could the Mixels ever have to fear from these little gremlins? I mean any one Mixel is larger than any Nixel. I guess in greater numbers like piranha they could be fierce. Well anyway, the whole gang of Series 1 looks great and now onwards to Series 2!
