An omnipotent being can basically do whatever the fuck he wants, if he says that gravity is not gravity then it's not GRAVITY! That's just how it works with an omnipotent, anything he says goes... Or anything does is considered logic to his perspective. A human mind could never imagine how powerful an omnipotent being is because we aren't that smart enough to realize than an omnipotent being can do whatever the fuck he wants without no consequences. If Kami Tenchi has a limit to his omnipotent powers or consequences that follow him then he is not omnipotent, just nigh-omnipotent. The best example of an omnipotent being would be God from the Bible, One Above All, Man of Miracles. An omnipotent should be above anyone no matter how powerful they are unless they're of course another omnipotent.
I'll take my chances...It really depends on how I swim... Sharks generally mistake their meals to being seals, fishes, etc so if I try not to look like some giant fish swimming strangely fast and try gradually swimming I'll make it... Or not... It all depends on your luck and the circumstances of the Shark.
Referring to Chapter 590
My thoughts on this chpt along with latest chapters is that this one was done good and excellent, we finally gotten to see Itachi's perspective of the Uchiha Massacre and see more of Itachi's emotions. Even though this we knew everything about it we at least saw that Danzo actually tried helping Itachi in protecting Sasuke, Tobi admits he's a Uchiha and wants to take revenge on the Uchiha, and how Itachi's reactions were. And now the curtains get to unfold as Madara notices he's being pulled back to the World of the Dead. The Bad news is that we don't get to see anymore of MADARA! But we all knew he was gonna lose someway or another and this is the only way he can as the Kages are powerless to his powers. I can't wait to see Sasuke's reaction in the next chapter and how Itachi words will affect Sasuke's decision on destroying the Kohona. Oh yeah!
We get to finally see Tobi in action now that he doesn't have any of the paths to back him, it's about time.
Not a clone but as you said he could be the empty shell of Madara as Tobi states so himself he's nothing but an empty shell of his old former self, and Madara in the past by the time was aware of the splitting technique from the Third Tsuchikage which Madara probably used just like the Tsuchikage did but that's only my assumption, other than that there are no other explainations of who he is but Rikudou's son. Recent chapters reveal he is a Uchiha and hates the Uchiha Clan....
Are you serious? Godzilla with ease.... Godzilla is larger than mountains and can sweep a plain field with just his tail, plus his durability is wickedly tough and no one in HST can even scratch him. Hell... He doesn't have to use his ray beam, he'll just stomp on top of team HST. Mountain Busting is a Joke in the GZ verse, hell even a low tier Kaiju like Baragon can mountain bust. Godzilla in final war was shown shooting a giant size monster Hedorah out of earths atmosphere, also Godzilla destroyed an asteroid that carried the momentum to destroy Earth. And no one in the HST is immune to radiation, so all Godzilla has to do is fire one beam and it's over.
Well going off by your feats it's reasonable enough to say that Shakuma wins though just to inform you speed was equalized.
Those feats shown by FormerCrimsonKing are of him restraining himself as he says because he is waiting for the protaganists to give up Elie.
He is shown capable of spamming the meteor rain attack meanwhile using other attacks.
Shakuma is alot faster than Madara.
Shakuma is faster than the fastest flying ships in world of RAVE powered by magic.
Showing his speed, note that the characters attacking him are casually hypersonic already.
Showing a bit of his destructive ability.
Elie having full control over etherion using it to attack Shakuma.
Shakuma able to defend against power of that level. If you don't know how powerful etherion is, it is capable of defeating Endless.
Endless>>>>>>>>>>Madara's perfect susanoo
With a finger beam it was able to do a feat similiar to Madara's but on a much greater scale travelling thousands of kilometres across the planet.
Elie creating tornadoes with her etherion power against Shakuma.
Shakuma able to dodge easily them easily.
Well the creator of FMA did stated that the Truth is basically Omnipotent so going off by this he should win as there is no arguing to an omnipotent being because they can basically do whatever the fuck they want.
