Kid Danger : I would myself would win against Donkey Kong,Kirby,Link,Mario,Mega Man & Yoshi

They’re a bit too strong when compared to myself, probably Mario if he doesn’t have power ups but even I’m skeptical.

Against each other, Kirby hands down since he can inhale and copy them and use their powers for Kirby’s own gain. Either Kirby or mega man if mega man able to defeat and have their powers also.

Edit: to be honest I didn’t read the kid danger part I thought it said kid link for some reason. I also asked how would you beat mega man?

Wait, how do you plan to beat Mega Man? He's the Super Fighting Robot!

Minuano : i would say Kid Danger would use weapons

Donkey Kong has got strength, Yoshii can eat enemies and throw eggs, Mario is well balanced, Kirby can inhale and copy enemies. but at the end of the day I think Mega Man has the edge here.

Here are the reasons

Mega Man has a powerful Mega Buster that can do serious damage. He can also charge it. In addition, he can copy weapons so he could use a weapon of a previous Robot Master.

Mega Man has very good strength. He has lifted the heavy Charge Man and threw him. He also has defeated Guts Man, Hard Man, and Stone Man. These robot masters are heavy and bulky.

He has demonstrated he is good at hand to hand combat as well.

Mega Man has is made out of strong material. This is why he has been able to survive being thrown.

Also Mega Man's Brother Proto Man would likely pop in to help his brother. In the games Proto Man often helps Mega Man.

Of these two characters I think it would be a good battle between Kirby and Mega Man.

Kirby like Mega Man can copy weapons and use them. Also Kirby can summon power ups mainly the star rod. Kirby is also very strong.

So yeah I would say Mega Man would win in a very hard fought close battle.

If Mega Man did not win it would be Kirby.
