Luigi VS Mario:  Would be insanely close, the winner winning by the most minuscule details (Physically, anyway. Weapons are a different story.) If I were to predict, I would say Luigi wins, due to his better jumping ability, being faster than Mario (I would think running on water would make you really fast), and the fact that power-ups like the Thunderhand and the Poltergust don't suffer from Video Game logic, and won't be lost in one hit.

Sonic Vs Tails: I do think Tails will take it. Tails is stronger than Sonic, his flight gives him better control over where the fight happens, his weapons, much like Mario to Luigi, won't be lost after one hit.
