No he is just the guardians of all the multiverses.
Wasn't it in 84 only a multiverse ??? it was only later that marvel officially approved that they had a omniverse in 90 ore something like that not sure.

Actually LT is the Judge of all the Multiverses.
Merlyn and Roma are the Omniversal Guardians.
Saturnyne plays a role too.
Up until Nov. 86',
Marvel was just a Multiverse and the Beyond Realm in continuity.
Then it became a Multiverse, the Beyond Realm and the New Universe.
The Omniverse was mentioned afterwards in literally a few titles, then it was made Official in 92', when it was stated and depicted as Quasar crossed over to the New Universe which was located Outside the Multiverse.

They're not below or above,
I never rank Merlyn and Roma in a Hierarchy because IMO they stand apart.
They're like TOAA's "nephews and nieces" if you ask me, I'm speculating with a bit humor, but the things Merlyn has been able to do and been Permitted to do, are unbelievable.
Merlyn and Roma manipulate every event they have been involved in, so I can never tell what their true powerset is.
Sometimes they seem like "God and his Daughter" playing around with the Omniverse, sometimes not.
Still, anything LT can do, Merlyn or Roma could do, namely the greatest task of all, obliterating the Omniverse, it's within the power of both.
Have they ever done that, and Roma was killed by Abraxas and Merlyn couldn't do something about MJJ which I believe it would be a walk in the park for LT to do something about???, And couldn't LT IF and ONLY IF he deemed it necessary do it to IF he found it necessary
Thanos stomps. HOTU is a manifestation of TOAA's power.
TOAA>Beyonder. LOL
PS: there is only one living tribunal, his m-body represents the real power of the 'real' living tribunal. If LT was truly second to TOAA than thanos pwns. Oh as well as that classic beyonder was said to represent the power of the writers over the comics. Stan lee (TOAA) > all the writers. Stab lees power was given to thanos. Holy shit.
