XRR, if you've got the bomb pack and the sword. It did a whopping 1 point of damage to him (and emptied my meter, resulting in my death). The only effective attack I've used is the bomb pack, and that manages to get me around 20 points.

I'm at level 5, and I'm pretty sure I have to be at a higher level to have a chance. At the very least, my equipment needs a boost. Then, maybe the program will do more damage.
