|First appearance||The Secret Package|
Spidaro is a spider-like Bakugan that stands up on his legs. Each arm has two long sickles that slash his rivals. A paralyzing plasma beam shoots from the top of his head. He can curl up under the shell attached to his body and ram the enemy.
In Mobile Assault, another army of Pyrus Spidaroes appeared.
In A Royale Pain, an Aquos Spidaro is noticeable during the battle royale.

- Its description on Bakugan Dimensions noted it being mechanical, but Spidaro showed no mechanical qualities in its few anime appearances.
- Its ability Drain Impact has a different effect in Mechtanium Surge than it did in Gundalian Invaders.
- Spidaro looks very similar to Krowll. They both take on the form of huge arachnid Bakugan, and seem to stand up the same way.
