I made some MoCs a while back, and procrastinated publishing them. Brain Attack was my personal favourite wave of Hero Factory, but I thought I could do at least a little better. Massive wall of images incoming!
Pyrox-
Bulked him up a bit, made him a bit more of a Minotaur. The back was my favourite part to build

Storm Beast-
Filled him out a bit, added some colour to his bones. Once Again, I really like the back

Aquagon-
I gave him another sword after I took these pics, which really helps. Kept the original arms for the most part, and gave him a custom shoulder/arm attachment.
Bruizer-
Went for a heavily asymmetrical design with this guy, to make him look a lot more jagged and rock-like. Accentuated his right arm and got rid of the nasty function. Also added some actual orange and red to his colours, to give him a volcanic look. The fingers are a bit weird, but they’re okay.
Scarox-
Put him on four legs, made him more buglike, and gave him some more gold. Not sure how I feel about this guy, but oh well.
Ogrum- has layers
Gave her yes I headcanoned Ogrum as female, because yeah a reverse Pyrox treatment, with one bulky hand and one normal hand. Once again went the asymmetry route to give her a more organic look, and gave her more lime green. The mace/club/whatever attaches a bit weirdly, but it works, and is much more poseable than before. The shoulders were tricky, but I think they came out well. I removed the ribcage after I took these pics, and replaced it with a three long/four long CCBS shell, which looked a bit nicer.
Group shot-
Didn’t make a Dragon Bolt upgrade/revamp because I think he’s fine the way he was as a set. I also made revamps for the Heroes, which I might post eventually, by which I mean when HF gets a reboot, but that’s all for now. Thanks!
