Lotso is a pink teddy bear. He only appeared in Fantasia in the 100 Acre Wood 2 as the hidden main antagonist. Lotso plotted to rule the Hundred Acre Wood after Pooh Bear had gone to the Pride Lands.
But Lotso is defeated by Buzz and Woody. He was later found by a man who had him strapped to his garbage truck (More likely He remained there for eternity).
