Freakazoid!: Made out of a Spiderman body and some Super Sculpey.
The Bald Eagle: The old guy from my story "The Ultimate Weapon" made from a Total Justice Hawkman and a lot of Super Sculpey.
The Infragable Krunk: Just a slight repaint on a Hulk action figure and maybe a new head for good measure.

Here is a list of what to expect:
Zan and Jayna: The Wonder Twins come to life from Alpha Flight's own Northstar and Aurora.
Gleek: The Wonder Twins' monkey. Most likely made from scratch with Super Sculpey.
Monkey: From Dexter's Lab. Probably also made from scratch with Super Sculpey.
