@Kurohige: I go with Z here.. seeing that he is a multiversal entity (not by DC but by where he has been), he should be able to bend the laws of a single universe.. He created his own dimension outside the reach of the Choushin where there he monitored Tenchi and the others, and also played with their fate.. I don't see anything stopping him from going to a higher dimension and play with Gio..
Z is not a multiverse buster or multiversal defense, he needs universal for 2 wings and he has 5 so something above low universal will do. He can monitor Giorno but not GER which is independent just like Silver Chariot Requiem or Notorious B.I.G. His actions would also be negated before he could leave. Z is more effective in person. why would he leave the dimension when it would be more effective to use his LHW? His durability should only be around universal+ not that it matters against GER's ability.
GER does everything Kurohige said it does. But the LHW's are pretty much the same thing as GER but I go with Z because of his higher level. He's multiversal while Giorno has only shown universal.
The Chousen stated that 10 LHW existing would destroy the universe, the LHW are>>>>Z, Z himself only has 5. It took all 3 Chousen to keep Tenchi, who's power was above Z to keep from shattering the multiverse. Z is not even universal without LHW.
the scope of the LHW is still greater and has been used against more powerful opponents.
The opponents being more powerful mean nothing given what the LHW are. They could be used by a 10 year old kid and still easily fend out planetary threats. The true LHW are the life force energy of the Chousen so naturally regardless of who you are if they hit you then you're done for. The problem here is that they will never hit as Z's actions and will are set to 0. LHW can delete matter and energy itself from existence, GER uses none of those as his ability as Stands are not energy or matter, nor are the effects of GER.
@Kurohige: considering that all entities higher than the third dimension don't exist in the first place according to the laws of the third dimension, and yet Z is still above the D3 in power.
Z exist outside every dimension, not just the 4th, in fact he exist in a separate dimension not within the Chousin's range, which is the dimension he was in when spying on Tenchi and the girls.
also Z can be anywhere in the universe at any given moment and manipulate the laws of the lower dimension, meaning that fourth dimension time & space. Speed is really a non issue here.
Also Z said that the only way for Tokimi to stop him was to destroy the universe, well that is indeed false because what was said in japanese was this that she couldn't stop him without destroying the universe, it does not say she would kill him, and this is supported by the fact that in order to completely stop Z Tenchi had to practically destory all of reality and every dimension and it is also supported by the fact that Z wasn't completely erased by Tenchi's powers going wild even though he was hit point blank with the full force, knocking him unconscious, which allowed Tokimi to start again with him.
Therefore Z is Multi-universal and a universal entities power would only be a minor annoyance at best. so while yes you would usually be correct that similar abilities would cancel each other out, the big deciding factor is the scope of the ability.
GER is only universal in scope while Z himself is easily Multiversal in scope.
Let me give you another example of this so you can better understand it. Z's five LHW vs Zinv's three. ability wise they are exactly the same, however unlike Zinv, Z has two more wings and can work on a broader scale.
The speed argument alone is debunked as he was seen traveling to Earth, he did not arrive in a mere instant, Z never demonstrated that kind of ability otherwise he would have had an easier time blitzing Tenchi. Z is only MFTL, he does not have infinite speed or reaction like GER, only the activation of the LHW can be considered instant. GER is faster than Z, Z has automatic shield but it wont help since there is nothing to shield against, there is no attack happening.
Also with Tokimi Z himself stated that the attack to destroy the universe would indeed stop him, and Tenchi's power was simply going out of control, that was not a means to beat Z. Even if such an attack can't kill him it is enough to render him into a state on which he can't fight. it doesn't matter anyway since GER is not going to harm Z, there is nothing to suggest that he will be able to prevent his actions from being negated. The LHW require contact to work, GER does not make contact, nor does it deploy some sort of field to use it's ability. It just happens. GER is not energy nor matter, Z will also be unaware of GER and it's ability. He wont even know what he is fighting or defending against, he will only see and experience Girono.
The other problem is that those feats are displays of durability, GER's ability ignores that as it is not an attack, also it can negate things without them coming into contact with him. Z taking universal level attacks don't mean anything since he has not shown resistance to this kind of reality warping on that scale. Z himself has only demonstrated casual planet level ability without LHW and even needed ships to fight before he got them. LHWs function by converting damage into harmless energy as word of god states however things like psionic attacks, GER etc are harder to judge. If something is Multiversal then any attack be it phasing or not bypasses the LHW regardless. Phasing won't work an LHW as it cuts pseudo dimension and 3 LHWs allowed Tenchi to survive a black hole. There is nothing to prove it defends against causality manipulation like GER, which rewrites history so that anything that is “too fast” gets trumped before it happens.
Two LHW can be overwhelmed by attacks stronger than a universe buster. Even with 5 eventually the LHW would fail at some point.
Gold Experience Requiem,stops the attack from ever happening, can completely disable the opponent body, mind, and will, and can send them spiraling off into an infinite death loop.
Ultimate hax > Ultimate speed and destructive capacity which is what LHW are. GER is not doing anything destruction therefore the LHW are not able to nulify it, it's matter manipulation, energy.
At the end of the day Z can't defend against his actions be negated, GER can't kill or harm Z but the LHW only protect him from matter and mental manipulation. Tenchi needed 3 LHW to escape something like gravity. GER easily negated universal time erasure. It's a draw because neither can do anything to each other. The only thing Z has that matters are LHW but Z needs to use them, GER is faster and can stop his actions or will. GER in independent, killing Girono does nothing anyway. Both the LHW and GER are instant, but Z is not instant. GER will continue to disable all of his movements. The very concept time and DEATH ITSELF are negated eternally by GER. It's a draw.
