A new item called Trainer Card has been added to the Shop. Using it will give you a rarity-based item which is either Common or Rare. Using that obtained item will allow you to receive a random trainer avatar of the specified rarity via Advanced Item form.
There is a new tab on the profile called RPG. It will have much more relevance in the future, but for now it's just for Trainer Avatars. You will find the member's chosen Trainer Avatar and member's unlocked Trainer Avatars there. If no Trainer Avatar is chosen, Red(Male) or Leaf(Female) will be chosen on default.
Trainer Avatar trading has also been added. This works similar to item trading, but will take longer because it requires the Service Bot. You will find the link in the Shop.
Thanks to Sophie (not tagging so it doesn't send e-mail) for the original idea years ago. Thanks to @Charles and @AJ_ for reviving the idea after migration.
These will NOT replace the traditional avatar system. They are more of a first building block towards the RPG system.
It is possible to get a duplicate avatar. Member economy exists to trade/sell your for the duplicates, but please be careful of scams.
Trainer Avatars are NOT gender-locked.
If you forgot your unlocked avatars, you can find them on your profile.
Be aware: because this is a more complex system, Admins will be slower at verifying the Service Bot forms that are related to Trainer Avatars.
