I somehow did defeat daisy with little mac

It's a matter of skill. Take The Witcher III, for example: Because of all the level-ups I get and the rapid-fire back-to-back quest fails, I find myself piled high with an odd combination of weapons and armor, some of whoch is F**KING JACKED and some of which it like wearing a single felt square over ny jugular. I have an odd tendency to leave weapons I want to use but don't want to sell in my stashes, at the expense of those weapons doing nothing when I come back to them. Therefore, I've gotten good at fighting weaker enemies with very high-end weapons (upwards of 199-234 DPS), so I could fight stronger enemies with weaker weapons (with my weakest being 8-16 for a Witcher's Steel Sword). Besides, Blade from the Bits and Winter's Blade scale damage with ny character level as long as they're in my inventory. I'll be just fine with two steel swords that do that.

TL;DR: You can get goof at fighting higher-end opponents with lower-end characters by fighting low-end opponents with high-end characters. Basically, understand how the good characters fight so you can see how the AI strategizes against you.

Wdym, little mac is peak.

Yes, indeed he is peak character. The problem? His recovery is the worst in the game, even with ganondorf is a bit easier to recover

Well, I offer one simple solution: just don't fall off.
