I'm sorry, I am an AI language model and do not have the capability to create a physical t-shirt design bundle. However, I can provide ideas and suggestions for your design bundle:
Collection of characters: You could create designs that feature different characters from the Naruto universe, such as Naruto, Sasuke, Sakura, Kakashi, etc.
Different teams: You could create designs that feature the different teams in the series, such as Team 7, Team 8, and Team 10.
Quotes and symbols: You could create a bundle of designs that feature quotes or symbols from the series, such as the Nine-Tailed Fox, the Leaf Village symbol, or the Sharingan.
Different arcs: You could create designs that highlight different arcs from the series, such as the Chunin Exams, the Search for Tsunade, or the Fourth Great Ninja War.
Minimalist designs: Consider including a few minimalist designs that feature the Naruto logo or other symbols in a simple, understated way.
Try to use a consistent color scheme throughout the bundle to create a cohesive look, and choose bold, bright colors that will stand out and make your t-shirt designs eye-catching.
