Mirkwood’s #1 Trainer. Thranduil has always liked fairy-type pokémon and filled Greenwood with all the fairy types he could find. (This may have been because fairy-types are immune to dragon-type attacks; something he’d value very much.) You can scarcely find fairy-types anywhere else but Mirkwood by the Third Age!
Thranduil’s fairy-types help keep Mirkwood enchanted and they often will fool travellers and confuse them so they don’t penetrate as deep as Thranduil’s fortress.
It is the presence of so many fairy-type pokémon, who are resistant to both bug-type and dark-type attacks, that has slowed down the spread of darkness from Dol Guldur into Mirkwood but, alas, fairy-types are not very strong or fierce and they have been unable to stop the spread entirely.
Elves do not use pokéballs. They have more than enough time and patience to train pokémon without restraining them. Since the end of the Second Age it has become very unfashionable to battle with pokémon among elves and, instead, they have been treated as allies/treasured companions who choose to fight alongside their elf trainers.
I went a little extra with the sparkles and sunbeams on this one. I figure Thranduil knows how to lounge on moss-covered boulders and still diva it up when posing for a picture. XD The pokémon from left to right: wigglytuff, snubbull, cleffa, igglybuff! There was a lot more detail I could have put into this, especially the colours and depths of shadows etc. but at some point I have to put the tablet down and just post it.
