Moneybags

Moneybags is a greedy bear and minor villain in the Spyro series. He first appears in Ripto's Rage, where he charges Spyro a "small fee" of gems in order to progress through the game. He charges these fees for anything, from learning to swim to opening a bridge, and they are usually outrageous. In Year of the Dragon, he is more villainous when it is revealed that he and The Sorceress made a deal to hold her enemies ransom so Spyro could pay a "small fee" for their release. Although still infatuated with gems, he seemed to have reformed in Shadow Legacy, having started a family and and opened shops.

Spyro 2: Ripto's Rage!
Moneybags owns a castle in Summer Forest, Autumn Plains and Winter Tundra, until each had been usurped by Ripto. He wishes to lay claim to the gems Spyro collects, and is seen at many plot-crucial points in the game. After Ripto's defeat, Elora forces Moneybags to reimburse Spyro by handing over all the gems he collected, to which he strongly objects.

Spyro 3: Year of the Dragon
Moneybags returns with more evil intentions. He has worked out a deal with the Sorceress to hold her enemies (Shiela, Sgt. Byrd, Bentley and Agent 9) captive and ransom them to Spyro for outrageous fees. Following the Sorceress' first defeat, he plans to sell one of the dragon eggs in Avalar for some quick cash, only to be intercepted by an infuriated Spyro. After an exhausting chase, Moneybags resolves to retire as a haiku poet in Spooky Swamp.

Enter the Dragonfly
Unlike the previous two games, he only appears once in the Dragonfly Dojo. He has apparently gone through with his plan to become a haiku poet, and mentions that the shine of gems are an inspiration for his poetry.

Shadow Legacy
Moneybags is arguably redeemed in Shadow Legacy, and has started a family and is considerably friendlier. His wife and four sons share his obsession with gems. Instead of charging Spyro fees at various points in the game, he has opened a proper business and has his sons sell goods to Spyro.

Trivia

 * In the Skylanders franchise, there is a character named Auric that "bears" resemblance to Moneybags. Though Auric's relation with Moneybags remains unknown.
