As if the packaging size and cardback layout differences weren't exciting enough, the in-pack premiums and corresponding offer stickers provide collectors with a whole host of variations/combinations to track down. Premiums packaged within the bubble and located behind the action figure include: mini-comic only, poster only, mini-comic and poster together, and lastly no premium whatsoever.

The mini-comics packaged within tri-lingual packaging contain unique qualities compared to those found in Kenner and Kenner Canada packaging.

To date it appears only the first twelve 1st series characters were sold on this unique packaging style.
