Mine would be from Tales of Symphonia, I called him "Oh-I'm-A-Man-I-Just-Look-And-Sound-Like-A-Girl", tho his name is Mithos. He was a fun boss.
Number two would probably be Perfect Chaos from Sonic Adventure (Dreamcast):
He was an also fun boss. Both were time consuming.

Dark Falz from Phantasy Star Online.. i loved the beautiful scenery before encountering him.. but then everything is covered in darkness *-*
And if you thought that you have won he changed into his next form XD
I was thinking "That was the final boss" from that game? Then I remembered, I was thinking of Phantasy Star Portable (PSU for the PSP) That game was so fun.
