Ganon (Hyrule Warriors)
What a whale, this Ganon. The beast stands a million feet tall and tromps around like a troll. He is like a mixture of Twilight Princess Ganon and Ocarina of Time Ganon. This beast resembles that of TP but walks around more like that of OOT. This fearsome beast is just that--fearsome. The Hyrule Warriors Team did and excellent job with this final boss. Ganon first appears in the final story level of the game Hyrule Warriors. When Ganondorf is defeated by Link (or whoever else you're playing as for this final level), he will transform into his beast form and attack. This is a throwback to many previous games. The 2D games, especially, since Ganondorf (the Gerudo) was never even present for them. This pig-like monster is immense, but there's a strategy to defeating him. It takes all four of your items to get the job done: The Bombs, the Bow, the Boomerang, and the Hookshot. For the bombs, Ganon will lift up his hand and charge a fireball. You only have a tiny amount of time to toss your Bombs (NOTE: You must be in range for this attack to function properly) at the hand. Once you do, Ganon will attack with another one of his attacks, unable to throw another fireball again. For the Bow, Ganon will lift up his forearm (which has a beam-shooting eye inside it--ewww!) and shoot a beam at you. You must shoot the eye to defeat that stage. Next comes the Boomerang. Ganon has two stalks on his shoulders, which will shoot seeds at you. They'll be exposed for a moment after firing, so after shielding to block the seeds, you must throw your Boomerang. The last Item Stage is the Hookshot part. Ganon will lift into the air and start to fly. He'll breathe fire at you, but when he's done, you'll have a moment to clamp onto his tail with your Hookshot.
Once you've gotten past all his Item Stages, Zelda will grant you with the Bow of Light. Ganon will proceed to leap at you repeatedly. The procedure is to dodge, then shoot his glowing forehead with a Light Arrow. This will open his Weakpoint Gauge, which you can then hack at. Once you've repeated this process enough times, Ganon will be defeated. In the magnificent cutscene that follows, Ganon will roar horribly before Link, Lana, and Zelda rip the Triforce pieces from him. They then obliterate him with the power.
With all that said, you must be wondering: Was it a good final boss? The answer is YEESSS! There are few things in life that are more satisfying than when you plunge your blade into Ganon with the final blow. The credits will follow, which I advise you to skip, since they have Cia in them (yuck).
Ganon appears a few times throughout Adventure Map stages.
This is how Ganon looks in the original Legend of Zelda:
