Welcome to the Wario Forums, Kiwi! Don't worry about being a newer Wario fan, I only really got hooked on the greedy fatass in early 2024 because I played Wario Land 3 compulsively. Hope you have fun here, even if it's a bit quiet.
I'm not too sure on the canonicity being stated on DK's fight with Little Mac, but for Starfy, Wario appears for all the levels of a stage, helps you progress, and even teaches Starfy a new ability.
I mean, in the case of Punch Out and Starfy, the characters actually play a genuine role in what's happening. In Kirby Super Star, that one is literally just an easter egg and has no weight on the Dedede fight. Not really comparable in my opinion.
Hi!! Welcome to the Wario Forums, things might not be too active, but there's sometimes an occasional spark of life. Nonetheless, I hope you enjoy your time here! :cool:
Wario Land 3 had something like that, you get new treasures that give you new powers which allow you to reach treasures in other levels that opens up more levels.
