Tornado
For an instant, Max couldn't make himself move. He stared down in horror at Tom, who was lying on the ground, and at the weird metal spider thing on top of him. Its eight segmented legs of steel pinned each of Tom's limbs while a pair of slicing blades popped out of its silver belly and headed for his friend's head. Somehow, in the midst of all this, Max noticed words printed on the back of the spider's round body:
METASPIDE
Manufactured by Tomikins Industries just like the Gnome spaceship.
He snapped himself out of his daze and grabbed the closest chair. Picking it up by the back, he swung it as hard as he could and smashed it into the creature, sending it flying off Tom and clanking along the paved stones of the pathway. Tom scrambled to his feet and joined Max; Hana and Molly were right next to them, staring at the thing Max had just whacked.
