10 Comic Book Characters Who Are Just TOO POWERFUL!
7. Superman
Superman has always been the benchmark for superheroes. At DC, there is Supes, then every other hero comes after.
Before Crisis on Infinite Earths, his power was shown as almost limitless - he pushed suns, traveled through time, had a genius intellect, and had a vast array of powers that writers created as needed (like super-ventriloquism.) Stories involving this Superman often took off into flights of fancy because writers had no problem gifting him with new, one-time only powers as needed.
Post Crisis, Superman's powers were scaled back, but he still had super strength, invulnerability, speed, freezing breath, heat vision, X-ray vision, and flight. There still wasn't much to challenge him, as he has gone toe-to-toe with Doomsday, Mongul, and Darkseid, surviving them all.
Because Superman isn't a cosmic character who makes random appearances for big events, but one who appears every month, his huge power set makes him, well... not very compelling. He is so powerful on a regular basis that it takes something truly special to test him, and something that powerful will inevitably involve his partners in the Justice League.
His character may be about truth, justice, and the American way, but sometimes he is just boring as hell.
