No.5, the first flying colossus. I enjoyed this battle so much I was actually sad when it ended. =The feeling I got the first time I leapt onto it's wing and hung on for dear life is one I won't quickly forget.
No.8. The battle takes place inside what I can only describe as a giant leaning tower of Piza. You shoot the feet of the colossus and he falls to the ground from waaaaaaay up high (if you've lured him up that far). Great battle!
No.11. The tiniest Colossus of all, but ironically the most frustrating battle in the game. This is the one you scare with the flame, but I thought it was just such a pain in the arse to kill him. The first time you fall off his back he batters you something rotten until you can get all the way back up the path, round the corner, up the platform and tip him over the edge again. His attacks do very little damage, so it seems to have been by design that the journey back up takes so long. I hated this fight!
No.14. Similar
style of Colossus to No.11, but thankfully a much more enjoyable fight. I love how you climb the towers and make your way around the whole area as he smashes each one down with you on top. I also love the design of this boss, he's like a massive pitbull :mrgreen:
No.16. Final colossus, thought it was a bit of an anti-climax. The hardest bit is just getting to him, but after that it's very simple and not particularly enjoyable either.
And poor Agro

. Ending was good tho
