Superman hate aside(even though I don't think that's possible for some), I'm actually more curious why people would think Tyrant has any sort of chance against a team THIS stacked..? I mean, he's powerful and all, but damn...

My thoughts are that he can actually take as much damage as Superboy Prime can dish. I am willing to give him the benefit of possibly being able to weather their assaults for a time.
What are his defenses like?
-------------------------------
I've seen him use energy, in the form of force bolts from his eyes.
I believe that Tyrant may just be able to siphon power from them. They are organic life forms, which is exactly what he consumes.
Even their HV may be a food source for Tyrant? If they flew in and used no powers (which would be out of character for them), and they went purely physical, I believe that they would or could knock him out.
Tyrant wasn't at all like Galactus. Galactus deflated as time went on. Tyrant? Nope.
He kept up with a handful of herald level characters, which shows that he probably has the power to match their speed.
-------------------------------
That's one scenario. The other;
OWAW Superman is as powerful as Tyrant, Superboy Prime is nearly, and Ultraman with his K-nite addiction runs slightly lower.
Together they would just waltz on in, and beat Tyrant to death in fractions of a second.
-------------------------------
I believe that it would be a fight for either side.
Tough one, Ultraman has a high probability of getting taken out early. Which would leave Prime and OWAW to deal with, and together, I feel they stand a good chance considering how hard Superman was punching and how tough Prime is.
Not that Tyrant can't dish it. It's a close fight.
He has been affected by Superboy since Infinite Crisis, Krypto, etc. I enjoy Prime I hate Superman. Tyrant would make him cry though. Far more powerful and far superior showings. It isn't close.
