Dear Stacker Pentecost,
I notice that you are devoting your life to fighting the giant enemies of civilization. As a mechanical being that has not only spent its entire existence in this service, but was actually built for it, I am deeply sympathetic to your cause and wish your organization the best of luck.
I actually wish you more than luck for, as someone built to help in this struggle, it's often been an issue that I was not built larger. Like my creators, you seem to have constructed robot armors at approximately the same height and mass as the monsters you face. Unlike my creators, though, you seem to have at least four times the resources, given that you have four machines, where there is only one of me. I know, also, that you have several outdated machines of similar dimensions, and all of these are also similar to the titanic crabs, pterodactyls and whatever the glowing squidy thing was.
Have you ever considered taking all the material for several machines and making one that was much bigger than the giant monsters you face? Given that your plan of attack is always fisticuffs (my favorite professional approach, as well), punching the things to death would be considerably easier if they were much smaller than you. Many have been the days on which I wished I hadn't been built to the specifications, down to the meter, of the monster I had to pursue. If only I was as much bigger than him as he was than my creators, then the fight would have been over very quickly, perhaps leaving you time to get that nice Asian lady some psychotherapy.
