📝 Our Take

The Battle Arena is a fun, early Ninjago set that captures the essence of the theme's initial appeal. With its focus on arena combat and elemental powers, it provides a snapshot of the Ninjago world in its infancy, offering a nostalgic experience for long-time fans.

This set is perfect for Ninjago enthusiasts looking to complete their collection and for younger builders interested in a playable set. The build is relatively straightforward, making it accessible for children, and the arena design encourages imaginative play scenarios with the included minifigures.

Skip this set if you are primarily interested in complex builds or highly detailed display models. Consider newer, larger Ninjago sets like the Ninjago City Gardens (71741-1) for a more intricate building experience and display appeal.

⏳ Appreciating
The Battle Arena, released in 2011, represents a unique entry in the Ninjago theme due to its focus on arena-style combat. While not as iconic as some of the larger Ninjago sets, its age and relatively low piece count for the price point may contribute to its increasing value over time. The inclusion of exclusive minifigure variants also bolsters its collectibility. However, its play-focused design may limit its appeal to serious collectors compared to display-oriented sets. As a retired set, its value is likely to continue appreciating, but potential investors should be aware of market fluctuations and the overall demand for early Ninjago sets.

Compare Similar Sets

Compared to other Ninjago sets, the Battle Arena offers a unique play experience centered around arena combat. While larger sets like the Ninjago City Docks (70657-1) provide more intricate building and display options, the Battle Arena's smaller size and focus on play make it a good choice for younger builders and collectors interested in the early days of Ninjago. Its price point is higher than comparable sets due to its rarity, but the unique play features and minifigures may justify the cost for dedicated fans.

2 Minifigures Included

The set includes Cole DX and Bonezai. Cole DX is a desirable minifigure, and the Bonezai figure adds to the set's collectibility.
