I'm finished with mine now.
He would have continue watching the battle, if it were not for the momentary distraction of something blocking his vision for a split-second as he followed Sofia on the warpath. Re-adjusting his vision, he zoomed out and saw that it was a massive, thick, cable going from the building he was on to near the top of the monolithic edifice that was supposed to be his target. He realized what he would have to do and sighed; this was going to take a while. With great hesitance he began to go down the stairs behind him and moved through the still eerily empty building to a window two floors down.
From here he was just beneath where the cable came out of the building, and he started to grab a hold of it. It was then that he really began to realize that it would be a miracle if he could pull this off, but it was just about the only way he could think of. With that, he began the tedious, slow climb. Since not everyone wishes to hear about how he ever-so-slowly made his way along the cord, it shall be skipped entirely, as it's far long and about as interesting as watching paint dry.
Now we come to him climbing up the side of the target building. It seems that someone has locked and reinforced every single window up here, so he is now forced to navigate the exterior, it's amazing that he has not already fallen off. He climbs up and up the building, unable to find even a single window that he can enter until he's just a single floor from the top, where he can see that the final floor has a wide window on his side that gives a ledge big enough for him to stand on. As he clambered up he smiled, he was there. It was just too bad that Cthulhu slammed into the building, causing him to lose his footing and fall.
It was not the fall that killed him, it was the kinetic energy of the fall almost liquefying him on impact with the ground, followed by a bomb designed to dispose of his body and equipment in case of something like this. Although he himself was unable to complete the mission, the same outcome was achieved by the building being completely destroyed later in the battle. In any case, when the bomb went off a few lights changed on handful of computers back at the spacecraft he called home, and a timer began to count down on an edifice that bore the generic look of every cryotube, humanoid specimen jar and cloning tank in every science fiction production ever.
The first thought that went through the newly cloned Martian's head was "I'm just going to grow myself a new eye this time."
