President Snow from The Hunger Games trilogy reminds me of Scar. They both very evil antagonists and both brought so much devestation to their homelands (Snow with Panem and Scar with the Pridelands). They were like dictators when ruling and they are very cruel. Also, like the Frollo/Scar comparison, Snow and Scar are both old as well.

Katniss Everdeen from The Hunger Games trilogy reminds me of Adult Simba (but also Mulan lol). She and Simba both had very hard pasts, both are survivors who have fought for their lives, and they're very mature and serious when they are older. They're protective of the ones they love (Katniss with Prim and Simba with Kiara).
Bloo from Fosters Home for Imaginary Friends reminds me of Timon. Both of them are small (lol

), they're very self-centered, chatterboxes, annoying at points, and they often think they're better than everyone else most of the time. Plus, they make many stupid mistakes.
