- Not true, Kuramada clearly states in the hypermyth that Saints can fight up to 1000 years
- Sacrifice of Gold Saints was never stated to be just the power of the sun, it was stated to be more powerful than Athena's Exclaimation (Big Bang) so there's no denying. It was only stated to have the brightness of the sun
-Gold Saints are FTL, no denial of that, they can accelerate their speed to being FTL! In the beginning of EP G Aioli was stated to be Light Speed, towards the end Titan Hyperion said that Leo's speed had increased, also with Coeus the fastest Titan who countered Leo's Lighting Plasma effortlessly with one hand
Cancer Deathmask is probably the fastest Gold Saint here, Seiya was blitz by Deathmask who was about to soul BFR him until Mu countered him. Deathmask has blitz massive FTL opponents before, he was even beating Shiryu after mastering the 7th sense. His SekiShiki Meikai Ha seems omnidirectional given by the fact in the Lost Canvas Thanatos couldn't dodge it, The FTL Giga couldn't dodge it, Shiryu during the Phoeubus movie was caught by it, Seiya himself had no way of dodging SekiShiki. Even Wyvern Radamanthys had to counter it instead of dodge it.
- It's true(can fight for 1000 days) reraed Hypermyth, you have online in Spanish(since it appears that you're very fluent with Spanish). By the way their stamina was measured with fight of equaly powerful opponent. It was stated that Gold Saints can fight with themselves for 1000 days (the best measure since Gold Saints are more or less equal). With more powerful opponenst fight would last shorter. With less powerful also shorter.
- Well you're right of one thing. It was never stated to be as powerful as Sun, that was me being generous. As of actual power of tech, let's analyze several things.
First of all they used that technique in order to pierce Hades barrier (Wailing Wall), along with arow of Sagitaurus. All 12 Gold Saints died in the proces. It was stated that Gold Clothes have stored sunlight since ancient times(since they were created), as Dohko explained. They burned their cosmo sky-high and released all of the Sun's energy they concetrated and killed themselves in the proces. Just for the record Let's say that Gold Cloths have been created at the start of the universe 15 000 000 000 years ago (and they were created far, far later), and let's say they could store 10 000 000 000 000 000 000 000 J of energy in 1 day - which is the total energy of the Sun which strikes the Earth each day. Note that are of the Earth is >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> are of the Gold Cloth, but still let's say that Gold Cloth could store the same amount of Sun's energy as etire planet Earth in 1 day (we asume that even Sun was created 15 000 000 000 years ago and not 4 500 000 000 ago ). And we will asume that after 15 000 000 000 years Gold Saints sacrificed themselves and released all of their solar energy.
After all those years they should store 10^22 x 365 x 12 x 1.5 x 10^10 = 10^32 x 6570 . Total energy Sun has is 1.8 x 10^47. so even in this scenario it's <<<<<<<<<<<<<<<<<<<<<<<<< Sun's energy or to be more precise it's nearly 1 000 000 000 000 times less.
So you see that there is no chance that they could release more energy than Sun. There is no chance that they could release as much energy as Sun either (but i was generous) . Fact is that Gold Saints were all killed by power of the Solar Flare.
- No GS are only light speed(they were stated to be light speed limited in both manga and anime). At the beginig of episode G leo could punch 100 000 000 times per second, and wasn't stated to be Light Speed(that's just your conclusion from 100 000 000 punches). 100 000 000 moves/punches per second in less than nano-second reaction time which is required for light speed reflex. When he fought Hyperion he could do 1 000 000 000 punches per second or nano -second reaction time (by the way those 1 000 000 000 punches were with plasma and not actual punches as ). And Leo's feat is actually the greates speed/reaction time of gold Saints.
Out of all characters only Gods(inlcuding unselaled Titans, Typhon and Pontus) and users of God Cloth can be labeled as massivly FTL and that's by power scailing. 1 Sealed Titans (2 seal Cronos) and Thanathos and Hypnos are FTL but not massilvy rather 2-3 times faster than light speed. Since Gold Saints can keep up with them. 2 seal Titans and Spectres ( except 3 Judges or Hell) are slightly inferior to gold Saints and can't be labeled as FTL. Giants are also inferior(by a small amount) to Gold Saints and they are not FTL and for sure not massicly FTL.
3 Judges of hell should be slightly more powerful than Gold Saints (individually) but are not faster. Only Minos can be labeled as more powerful than any Saint, since Rhadamanthys had troubles with Kanon.
