Larry Koopaling
Cruel, composed and bland
Hoping it's new bosses, this game has the perfect reason as to why it's new bosses, and the Koopalings, sure they could go for another round but personally I feel like they've overstayed their introduction. Give it a break for a little.
Is the complaint that Koopalings are everywhere still legit though? Honestly they haven't been around for quite a while at this point. They've been left out of all the last mainline games from 3D World onward, and were introduced only as a late update in SMM2. Not even spin-offs seem to bother with them now. The last we've seen them was in Mario Kart Circuit.
I like the Koopalings and I still hope to see them making a grand return in the main series. Perhaps it's a good occasion to have them as interesting bosses with some new quirk mechanics. Though I honestly kinda doubt we'll see them in this game considering the recent trend.
