I would have to say the 3 final bosses of Sonic Advance 3, Sonic Rush, and Sonic Rush Adventure
Sonic Advance 3 was love because of the whole story behind Gemerl, a monstocity created from a once kind robot that had been corrupted to the point where he would betray his own master. Plus I liked how it took both Sonic and Eggman to defeat him.
Sonic Rush's Egg Salamander fight was cool because of how it took on two perspectives, one for Sonic and Blaze, as they fight they're respective Eggman.
Then there's Sonic Rush Adventure's final, which I liked mainly because it took a combination of both Super Sonic and Burning Blaze to defeat the machine, and you had the chance to swap between them at any point (and could basically complete the battle with either, though its more fun/easier with both)
Also each of these have absolutely amazing music to bump the already epic tone each of them have
