Ancient Saiyan

Ancient Saiyans (古代サイヤ人) are Saiyans from Universe 15, way older then Modern Saiyans. These Saiyans possess unusual ki then their modern counterparts.

Power
Unlike Modern Saiyans, Ancient Saiyans are actually way weaker then Modern Saiyans. However, A-Saiyans have the ability to transform into Super Saiyan easier then M-Saiyans. A-Saiyans don't have a 2% weaker base than M-Saiyans and M'-Saiyans, in fact they are much more powerful then Mid-Saiyans (Saiyans before knowledge about Super Saiyan).

Homeworld
Like the Saiyans from U7 & U6, They originate from '''Planet Sadala. But they never entered a fierce war with each other that collapsed Sadala.''' Then so, the Tuffles are still alive

Super Saiyan 4 Origins
When an unknown A-Saiyan fought against a monster stronger then him, he looked at the full moon and transformed into a Golden Oozaru with this power, he crushed the monster and ate it. The other A-Saiyans feared this and rejected the Saiyan. This Saiyan in his Oozaru form then attacked the others and ate them as well, he then reverted to a form powerful then the normal Super Saiyan, Super Saiyan 4.
