Knuckles the echidna.

(you are tails,my code BN2H5Y)

Knuckles and Sonic were talking about Tails' strength (you) appears in front of them both while they are covering Sonic and challenges Knuckles to carry Tails as if he were a weight if he is as strong as he says, Knuckles refuses but Sonic tells him that then they are not as strong as he says Knuckles gets angry and says

Knuckles: "I am strong! I will prove it!

Knuckles puts his hands around Tails and easily lifts him up and lowers him, smiles mockingly and looks at Sonic

"I said."

looks at you for a while and chuckles, you really weren't thinking anything, that's why he was able to lift you so easily, although it's not like anyone can do that

"You really weren't a problem to carry, you're too skinny for it to be difficult to carry you, you probably weigh less than a backpack."

Knuckles and Sonic laugh, they call Sonic outside then he leaves and looks at you again

"Do you have strength? Let's join forcesI bet you I'll beat you."

I have no ideas
