Namor may be an egomaniac, but that doesn't mean he's not a team player. This Namor uses the help of several avengers and even a Justice League member to aid him in the battle with the surface dwellers. He doesn't need combos to win; just really powerful moves.
Namor uses six buttons in the standard Light-medium-heavy punches and kicks tradition, although the buttons for them are swapped. While the buttons operate like most characters ((A) hurts the least, yet is the fastest, (C) hits the hardest, but is the slowest, and (B) is somewhere in between), the buttons are coded rather oddly; (X) and (Z) do 55 damage to the average opponent, which is roughly the same amount of damage as the (C), and (Y) hits harder, knocks down, and is safer than (Z). Ultimately, he only has two Normals while crouching (any of the buttons and any of the buttons) and they all hit low, with the buttons hitting . The Normals can't combo into each other from weaker to stronger strengths, but he can combo several crouching buttons into themselves.
Despite being unable to combo much, Namor has some really powerful Hypers that can help him do some damage. His Hyper Move can do 500+ damage to the average character, half of the average character's Life. He doesn't just have hard hitting options with meter though; His Sequence of Golpes 1 and Sequence of Golpes 2 do 284 and 304 damage each respectively. The Hawkeye summon deals 200 damage, which is about the same amount as an average character's Hyper. His attacks have insane amounts of priority, with the Special Kick in particular having a red hitbox that almost covers the entire character.
He's never in short supply of Power because of his ability to passively gain Power over the course of a match. His dash and backdash have no hitboxes on them, and he can go through his opponent; This gives him not only an overpowered way to approach his foe, but also a way to escape the corner. He can fly with (X)+(Y), but he can't attack while in mid-flight. An interesting tidbit is that the head pos and mid pos are incorrectly aligned.
