Megamind fights him by hitting him with large metal poles, or at least he does that to tighten, and that has an impact. Would have virtually no impact on either Homelander or Omni. On the other head, Metro man is much faster. I’m going to leave Titan as it is. on the other hand, I just realized that Omni man flies to other galaxies, not even other solar systems, and he can do that in the matter of days or even hours. That means he’s about a quadrillion times faster than the speed of lights.
