End of June I missed mentioning all the other Hero Mashers figures being found here.
Noted already were the Basics and 2-pack, but the Battle Upgrade packs and Electronic ones were found here as well... which is all of first wave figures here.

It was a Kmart that I saw the Battle Upgrade packs (the ones with the arm of another character included), as they were in their June catalogue sale.
