Kenner Canada produced a single 23-Back card style for the eleven 2nd series action figures. The carded Kalibak shown above illustrates that lone style: the "Superman Cape Offer" variety. Interestingly, the twelve first series characters do not appear to have seen release in this 2nd series packaging.
The bubble found on Kalibak's Canadian packaging differs substantially in form from the one used on Kenner's 2nd series Kalibak packaging. The bubble features indented regions giving it an "I" shaped frontal appearance. A formed plastic tray resides in the bubble to hold the figure in place and likely provide additional bubble support thereby to preventing damage in transit and at retail. While the Kenner Canada bubble may be more structurally superior than the Kenner bubble, I find it much less visually appealing.
