Tamadra (stylized as TAMADRA) are an iconic mascot of the game and exist in many forms. Usually, this refers to a special card that unlocks one awoken skill/awakening of a base card when fused.
In Japanese, Tama (たま) = Egg and Dra/Dora (ドラ) = short form for Dragon.
Regular Tamadra
These are cards that unlock awakenings when used as fusion material.
Latent Tamadra
These Tamadra grant various Latent Awakenings when used as fusion material.
Cosplay Tamadra
These Tamadra do not unlock any type of awakening. They are commonly met as standard dungeon enemies and used as Skill Up materials for the card they are dressed up as.
Reward Tamadra
A set of Tamadra which sell for a high amount of 
Coins and 
Monster Points. They are typically given out as quest rewards. While some of these still function as regular Tamadra by unlocking awoken skills, it is not recommended to use them this way since regular Tamadra can be acquired very easily, while these Tamadra have higher sale value.
Login Milestone Tamadra
A special set of Tamadra given at a certain number of total login days. They function the same as regular Tamadra but note that you can only ever get one of them, each. Many people keep these as collectibles.
