Canonically who is the strongest?

Master Hand/Crazy Hand
They aren't the real characters, they are animated figurines that are played with - the big ol' Hands are the kid's hand that is playing with the toys. Considering how a child can snap plastic toys, it's Master/Crazy Hand.

From the pic it's probably Samus, firing alien-destroying laser and bombs shouldn't match with boomerangs or swords

Kirby, unironically

>>381892593
If I had to guess, Kirby, Mewtwo, & Game&Watch are probably the contenders.

Between Kirby and Mewtwo.

Kirby, Mewtwo or Game and Watch.
SSE made it very clear how strong Game and Watch actually is.

>>381892593
Ganondorf, because only Link can defeat him.

>>381892593
At the height of their powers, probably Shulk, Pit or Bayonetta

Kirby
Ganon
Mewtwo
Samus

Samus is the weakest, hitting a wall makes her lose all her powers.

>Samus
How? Kirby has another dimension inside him. Samus has a power suit and arm cannon.
Mewtwo is basically a DBZ character and Ganondorf has the Triforce of Power.

Peach, because I said so.
