That is either a very small Nova or a very big Wily.

At that size, you probably could just Super Jump back to the city(with the risk of toppling several buildings).

I remember seeing something about torpedo locking onto opposing spawners, but am unable to find the footage of this I kinda remember seeing a couple years ago and don’t have a way to readily check this.

Wait, does this effect appear in-game when you shoot an opposing Spawner?
