This addon adds a new fictive Gym Series for the Radical Cobblemon Trainers mod. Some features require Mega Showdown to be installed as well. The Datapack was made for the Modpack "Toppermon" but can also be used without it. Several playtests were held to make sure that all gym leaders feel challenging without making them too unfair. All fights are meant to need preparation and team planning but are overcomeable.
I made this for the group of friends that I play with. The Addon includes 8 Gym Leaders, 4 Members of the Elite 4, a Champion and multiple Trainer fights in between.
Some of the Pokémon Trainers you will face are: Normal, Electric, Fire, Fighting, Poison, Fairy, Ice and Dark Type Gym Leaders. A Special type of Dancing themed Member of the elite 4 and several more trainers with diverse teams!
If you are looking for a difficult yet fair Gym Series that is not from any mainline Pokémon game, this might be the one for you. I RECOMMEND USING THE MOD VERSION OF THIS ADDON
Starting the Gym Series is the same as with any other RCT Series: You obtain a Trainer Card that you can exchange for the "Toppoh Series" one at the Gym Association Villager.
