Joes and Cobra operatives had animal companions; therefore, excluding them wouldn't have been right. Brummie and I have been talking about ideas of how we can include a few more of the characters who had animal companions.
G.I. Joe Minis Painted (9)
G.I. Joe team: 7*
Iron Grenadiers: 1**
Oktober Guard: 0
As I mentioned, I have prepped rules for personal use, to be able to use Timber in games of Squad Wars alongside Snake Eyes of course (either in a G.I. Joe team or an Arashikage Force).
