Here is a toxic sludge LEGO Bionicle figure built by Rockmonster2000. It’s here to cramp your style, chap you hide, harsh your mellow, or whatever it is they do with toxic nuclear sludge nowadays. This villain is just oozing with personality! It may not be the personality that’ll win over the nuclear safety inspector but it’s personality nonetheless. Where’s the Toxic Avenger when you need him?
That’s actually Hero Factory! It’s from the first wave, the one that predated CCBS.
Lego has made parts with nuclear/radiological markings, but I don’t see any here. Just green slime. Maybe this robot just likes mint jelly.
I get some Toxikita (Ultra Agents) vibes from the theme and color scheme…
