The number after the card name is which "edition" of the card it is (ignoring rarity levels 1 and 2).

Megatron this episode is "Megatron [12]" because there are 11 other Megatron cards of rarity 3 or higher. You'll note the R3 Megatron is [1] and R4 Elite Megatron is [2]. This was done to make matching bots with their correct weapons easier.

Megatron from Beast Machines was [9] and the R5 and R6 evolution cards from... whatever campaign it was that I barely played... were [10] and [11] respectively.
