Mr. Oz

Mr. Oz is a unique minifigure due to his distinctive design and the novelty of being from the LEGO DREAMZzz theme. Collectors will appreciate the specialized parts, like his asymmetrical sunglasses and the detailed printing on his torso and legs. The character's role in the DREAMZzz universe also adds to his appeal, making him a desirable addition for fans of the series.

His light bluish gray hair and beard piece, along with his unique head print, are key features that distinguish him from other minifigures. As a relatively new character, his collectibility will likely increase as the DREAMZzz theme gains popularity and the initial sets retire, making him a potentially valuable piece for dedicated collectors.

Mr. Oz appears in only one set, 71460-1 Mr. Oz's Space Bus, which was a $99.99 set. While not a limited edition, his exclusivity to this single set increases his potential rarity as the set retires. The availability of this minifigure on the aftermarket will depend on how many sets were produced and how many are parted out by sellers. Given the set's price point, it may be more likely that collectors will seek out the minifigure individually rather than buying the entire set.

As a minifigure exclusive to a single, now retired set, Mr. Oz has decent investment potential. The DREAMZzz theme has a dedicated fanbase, and unique characters like Mr. Oz are likely to see value appreciation over time, especially as the set becomes harder to find. Keeping the minifigure in excellent condition with all accessories will maximize its value. Comparable minifigures from other LEGO themes that were exclusive to single sets have shown significant appreciation over time, suggesting Mr. Oz could follow a similar trajectory.
