Mega Man VS Samus
Link VS Contra
my picks
Mega Man and Samus is the battle one could only dream of. Arm cannon vs arm cannon and multiple different abilities. I have to give Mega Man the slight advantage here. He has way more of a selection of weapons (54 to be exact) as well as the Rush adapters, and that annoying little bird Beat who is like a homing missile to enemies. Samus might have more powerful weapons, but she is no match for the variety of attacks Mega Man has. He uses a combination of charging up his Mega Buster as well as a few charged Heat Man shots to finish her off. He uses Beat as a distraction to get in her face when she is trying to fire.
Link and Contra seems like it is lopsided. On one hand, Contra guys have their guns to kill from a distance. However, Link decides he isn't fucking around anymore. He takes cover under his shield and uses his full heart power to shoot swords at the Contra guys. He then calls out some of his favorite weaponry, the Bombchu (which you remember could be guided for brief moments on the 64 games). He finds a safe spot and uses his homing style bombs to take out the alien hunters.
