Monstro was a powerful but peaceful Martian who visited Earth accidentally, by trapping himself in a rocket. Monstro created pandemonium on the streets of Brookhattan. The police assumed him to be the vanguard of an alien invasion. Monstro fled from the police, but was tracked down by the Shield. Mistakenly believing that Monstro was threatening his partner Dusty the Boy Detective, the Shield attacked him. Monstro immediately surrendered and explained his predicament. Monstro decided to stay on Earth, and the Shield attempted to look out for him but became annoyed. Monstro set out on his own for a few weeks. He attempted to help a number of people, but was taken advantage of by swindlers, after which he decided to leave the Earth altogether. Although he is not aggressive, Monstro demonstrated tremendous strength, speed, and athleticism, likely on a superhuman level. He was highly resistant to injury, shrugging off bullets without harm. He had the ability to read minds, which allowed him to instantly learn English. He also had the ability to morph his appearance to look like any human, or anything else he wanted to resemble. He had x-ray vision, allowing him to see through solid matter. Despite his power, Monstro was quite timid. He revealed that he had high blood pressure and that he had recently suffered a nervous breakdown.
