It would be fun to have an achievement for unlocking Secret Opponents in the BC and getting titles as achievements.

I think I have most of the secret opponents unlocked myself and have 78. My understanding is that the vast majority, if not all, of these opponents remain unlockable foreverindefinitely so this achievement should be just as possible for new players as old ones. I would never want to see this become unobtainable.

Perhaps it would be appropriate to have tiers for 10, 25 and 50 with the potential for more tiers later.

My own title suggestion: (I would love to hear others!) USER is looking for a fight

P.S. I'm not sure if the Random Challenge achievement is for unlocking secret challenger or random event challenger like Ice King. If it is already for unlocking Secret Opponents, then I suggest adding new tiers. If it is specifically for the random events then I am suggesting a new achievement.

👀 Oh, I'd like this! It would provide a bit more incentive to hunt for hidden challengers. Support!

This is an awesome idea! Side note, This Guide (spoilers) shows how to find the unlockable challengers for anyone who sees this & is curious.

Support!

Awesome ideia!
