At that size, that would be difficult.  It can't fit through the door of a gun ship, so it can't get the easy way out.  It can't climb up a ladder to tie a rope to hang itself, and even if it could, the rope wouldn't support it. With that much weight, trying to overdose on something would be very difficult as a pharmacy is not going to dispense enough to kill it, a normal human yes, but it weighs as much as 4 or 5 people.  It would need to ride that Scootypuff to somewhere high and fall off, but going uphill would drain the fuck out of that battery and we all know it is not going to walk uphill far enough to be able to die from a fall.
