4. Necky (Donkey Kong Country)
While I laughed many a time at the level entitled "Necky's Nuts," the World 2 boss in Donkey Kong Country was no laughing matter. Necky was as mad as they come, and that was before he reappeared in Necky's Revenge, the World 6 boss fight, which featured Necky again, only madder. I don't know what it was about Donkey Kong's mountain of rotting bananas that made it so desirable to a giant evil vulture, but I wouldn't want to get close enough to ask him.
3. Cucco (Legend of Zelda)
Of all the birds facing anger issues that we've seen, this is the only one that I feel is totally justified. Imagine you're a cucco, spending another beautiful morning pecking at dirt and fluttering around the garden when a green-clad psychopath bursts out of the bushes and starts beating you with a sword. After taking so many undeserved stabs, I think you have a right to call your friends and make an example of this little twerp. As the old saying goes, 'birds of a feather flock together, and will also straight up murder you.'
2. The Original Legendary Trio (Pokemon Blue & Red)
Articuno, Zapdos, and Moltres (the only 3 latino Pokemon) are not happy. While birds like Pidgey and Fearow could sometimes get annoyed, maybe even irked, they were nowhere near as pissed-off as a bird with lava for blood. Not only that, but these guys only appeared in the game once each. This is literally their only job, and they barely even cared enough to show up.
1. Falco (Star Fox Series)
Falco is a dick. Everyone else on Star Fox team is friendly to the point of annoyance, but not Falco he doesn't need your help, and helping him only seems to piss him off more. Frankly, I'm not sure what Falco has to complain about. He's a falcon, by far the coolest animal on the team, his buddies all put up with his endless snarky comments, and he flies a space jet for a living. What, are your space boots are too tight? Loosen up, dude.
