Disagree. A Tier 9 being with Mid-Godly Regeneration can return from being erased by a Tier 1 being with Low 1-C using Existence Erasure, as the potency of the EE doesn't matter if the erased aspect is within the Tier 9 being's ability to recreate. It's a similar scenario here.
Super Shenron can restore universes because Zeno's action was limited to erasing universes. The fact that it was done with 5D Existence Erasure is irrelevant, as Super Shenron only needed to restore the universe and its history.
No, it doesn’t work that way. Super Shenron doesn’t need to counter Zeno's EE directly to undo his actions; the two actions are separate. For instance, if a Low 1-C being uses EE to erase a planet, unless their EE includes some specific conditions that prevent what they have erased from being restored, even a Tier 9 with Low 2-C time reversal could bring that planet back.
Respect doesn't have to originate from something or someone being equal to you in power.
This situation assumes that, because no limits have been explicitly shown, the character's abilities should be scaled to the highest level within the verse. I disagree with this approach. The safest and most logical option would be to restrict Super Shenron's abilities to what has been explicitly demonstrated, rather than speculating on potential, hypothetical capabilities that haven't been confirmed.
