Yerp.
..... A wild Halo heroes figure has appeared!.....
No but seriously one did, the cyan orbital with the skull paint job homage to Emile, Its being sold by a person named Small-world-store,
I cant give direct links but this is what it is titled if you search on Ebay.
Mega Bloks Halo - Halo Heroes Series 1 Spartan Orbital Blue - VHTF NEW In Box
Like the last wild set I saw on ebay, Mega Bloks reminds you This isn't one of their trusted stores and can't gurantee product delivery, or proper price satisfaction, etc etc. Right now its on a Buy It Now option for 8 bucks,
Edit: Looks like he also has the neon green defender HH and Vale.
