Add these features to an existing Fort Max and we'll have a sexy, blocky, articulated giant to play with.
with all those addons i think just a new for max would be more logical, I'm all for add-ons but that seems excessive and gets into the relm of eithor articulated custom or brand new figure not simple mass produced addon. on other bit there are articulated spikes out already headrobots centurion.
Headrobots already released a new Cerebros head - both the Japanese and US versions are in a 2pack along with a small sword for Cerebros. Heck - there's even a Brave Max head if you went to TFcon and picked it up.
I'd be happy is someone just released an entire Cerebros replacement. Maybe a triple changing one with a computer mode, a head mode and a robot mode. This would work for people with new Fort Maxes, and with one ones.
