It first appeared during the second half of the trailer, when Adam was preparing to detonate charges on the train and ambushed them by dropping down from the ceiling.
Following the destruction of Atlas, it is likely that the remaining Spider Droids have all been destroyed as well.
The Spider Droid was dark gray and red. It had four legs on its abdomen, two arms and an upright oriented body. It possessed four cannons, one at the end of each arm, and two larger ones mounted on its shoulders.
It was capable of turning into a cannon configuration by merging its four cannons into one large cannon which produced and fired much stronger salvos. In Amity Arena this form also folded its legs.
The Spider Droid's color scheme was remarkably similar to that of the Atlesian Knight-130, implying that they were possibly made by the same manufacturer and/or are of the same batch of products.
In the "Black" Trailer, the Spider Droid attacked Blake and Adam after the AK-130s failed to subdue them. It managed to knock Adam and Blake onto a different cart of the train. Knowing how strong this robot was, Adam requests that Blake hold it off until Adam is ready to attack again.
Blake goes to fight and delivers a series of seemingly ineffective blows to the machine before jumping back. The Spider Droid attempted to fire its main cannons after that, but Adam, ready to attack, delivers a swift, powerful finishing blow that sends it flying backward while disintegrating its frame.
According to RWBY: Amity Arena, these droids were still prototypes, and their exact number was unknown. Following the destruction of the Kingdom of Atlas however, they have likely all been destroyed.
Powers and Abilities
It shared similar traits with a spider, such as the ability to hang in midair for an ambush attack. It appeared to be made of an extremely durable substance that could withstand both Blake's and Adam's initial attacks. At close range, the Spider was able to use its own body and legs to attack and even managed to wound Blake.
At long range, it could fire off each of its four cannons, though it could only fire one at a time at a rather slow rate of fire. The Spider's merged cannon had enough strength and force to knock away both Adam and Blake through the back of a train cart.
- Writers Kerry Shawcross and Miles Luna have stated, with particular reference to the "Black" Trailer, that technology powered by Dust glows, hinting at a possible power source for the Spider Droid.
- In the manga, the Spider Droid was actually a mech that was piloted by an AK-130 Android. After Adam destroys the mech, the pilot android climed out of the wreckage and attempted to attack him, but Blake destroys it.
