Some of the Dragon Slayers were trained by Dragons, while others gained Dragon Slayer Magic by means of Lacrima implants (as in the case of Laxus). For Lacrima implants, the Dragon Slayer Magic has to be extracted from a Dragon (that's my assumption). So how many Dragons in total, living or dead, exist in Fairy Tail? If possible please provide their names.
According to the Fairy Tail wiki, there are 18 Dragons who have been given a name.
However in the Grand Magic Games arc we learn that 400 years ago the world was ruled by dragons. Many a Dragon were slain, and thus, the humans became known as Dragon Slayers.
Dragons with titles:
- Igneel - The Fire Dragon King
- Metalicana - The Iron Dragon
- Grandeeney - The Sky Dragon
- Acnologia - The Black Dragon (The Black Dragon of the Apocalypse)
- Weisslogia - The White Dragon
- Skiadrum - The Shadow Dragon
- Zirconis - The Jade Dragon
- Atlas Flame - The Fire Dragon
- Belserion - The Sage Dragon
- Irene Belserion - Queen of Dragons
- Elefseria - The Law Dragon
- Mercuphobia - The Water God Dragon
Other named Dragons:
There are thousands, but the main ones (that trained the dragon slayers) are of a number of 5. (Igneel (Natsu), Grandine (Wendy), Metallicana (Gajeel), Skiadrum (Rogue) and Weisslogia (Sting).) There is also Acnologia, making a total of 6 main dragons. There are a lot of other ones, but these are the dragons worth remembering. Especially Acnologia. There are other minor ones, but I don't think they are really important to the plot. The number of names mentioned is of 13, though.
There are 18 dragons Igneel, Metalica, Grandeeney, Acnologia, Weisslogia, Skiadrum, Ziroconis, Atlas Flame, Motherglare, Scissor runner, Levia, Dark Dragon, Rock Dragon, Belsrion, Irene Belserion, Animus, Elefseria and Mercuphobie
