Gold Lightan from Tatsunoko vs. Capcom, lovingly recreated in his true form. The only Gold Lightans I've ever seen in Tatsunoko vs. Capcom don't really play fair, all they do is spam attacks, the most common one being the light jab or jumping and stomping. All characters except the other giant robot, PTX-40A, flinches without fail at his powerful moves.
All you do is JAB, JAB, JAB, the enemy won't even be able to attack, and Lightan can disrupt anyone in the middle of any super move.....This guy is friggin invincible. It's enough to make me rage.
Of course, if you're one of the pro types you'll most likely find a way around Spam Lightan, but he's hard to tackle with if you're not skilled enough. Why isn't PTX-40A spam? He's just a little bit harder to use than Gold Lightan, and a bit slower. But his moves pack more punch.
