Super Saiyan God 3 (LOTSG)

"I must thank you too for being strong enough that I have to go all out. This is my strongest Godly Form and the limit of a Saiyan's Power, Super Saiyan God 3."

- Kaestos upon entering his strongest state during his fight against Demigra. Super Saiyan God 3 is an overwhelmingly powerful form that is achieved after a great deal of training and mastering the previousSuper Saiyan God transformations.

Appearance
This form looks like the user's Super Saiyan 3 but with blue hair and God Ki.

Upon hearing of this form Goku had a dream about what he would look like in it, but he is still working to achieve it along with Gohan and Vegeta.

Usage and Power
The Ki multiplication of this form is 16 times that of Saiyan God, 8 times that of Super Saiyan God, and 4 times Super Saiyan God 2.

Kaestos considers this form the strongest form a Saiyan can achieve as even using a technique like Kaio-Ken doesn't increase his power beyond this level.

At his strongest Kaestos had a God Ki of 200 in this form, but nowadays he only has a God Ki of 12.5 due to not training seriously for 5 Million years. Kaestos recently began training seriously again and was later given the offer to train with Whis in order to quickly regaining his former power.

Kaestos first utilized this form against Demigra in his Dragon God Demon form and managed to match the empowered demon overall.

Shortly before Goku Black appeared in the present Kaestos showed this form to Goku, Vegeta, Gohan, and Future Trunks, however, he experienced great difficulty transforming and only held it for a brief second.

Drawbacks
Transcendent Aura: More so than with any other Godly Transformation, this form affects the Universe. During the fight between Kaestos and Demigra, the entire universe trembled upon the first clash.

High Ki Consumption: While not as physically stressful as the normal Super Saiyan 3 transformation or even Saiyan God, the energy consumption in this form is still considerable. This is a critical factor for the fighter to consider, especially if extended combat is a possibility, as they could find themselves over-exerted before long.

Unleashed Potential: Those who have this power-up can add it to the Super Saiyan God 3 form and unlock their full potential; however, if the difference between the two levels of power is too great, it will kill them.
