Created by Billy and Alpha, this was the first Power Ranger Zord controlled by telepathy, with help from a little Aquitian technology, that is. As it was an alien technology, Billy was unskilled and this caused the Zord to be very unstable. This meant that if Tommy was not in a focused state of mind, then the Zord would not respond properly.
This Zord was hugely powerful, firing blasts from the guns on its arms. When Tommy was under a spell by the Machine Empire, the Battlezord was adjusted to respond to Adam’s brainwaves.
