Volt Opt is more difficult than in the Dreamcast version of the game. If you are an Android, you will get shorted about 8 out of 10 times that he shocks you in his first form. Kill the center thing that hangs off the ceiling. Once that is down, shocks stop occurring more often. Shoot Volt Opt in the monitors when you see him. When the poles appear from the ground, find the red pole and take it out. If not, you will get a nasty shock that could short you out for awhile. Repeat these steps with 10 Monomates and 10 Dimates and you should be fine. Once his first form is done, he will become a huge red robot and have multiple attacks (but no more shocking). He usually starts by turning his missile pods towards you, and fires them after three seconds. You can avoid the missile by running around Volt Opt (get a 3-hit combo in before he fires them, then run). He will then turn his laser sights on you. Do another 3-hit combo and run. Keep running and when you hear him powering up, he will drop a huge pole on you. He does this three times. Yet again, you can avoid this by running. He will chase you with the laser sights twice. After that, he will heal himself by about 40. During this time, attack him heavily. He will then switch over to his front and shoot a floating ball at you. Do not stop running or you will be imprisoned in dirt wall while he charges up to do his ultimate attack. If you get hit with this ball in multi-player or online mode, call someone over to. They can get you out by attacking the dirt walls. Repeat this to defeat him and get good experience.
