the otsutski intake the energy of planets and stars (stated verbatim) if they can intake this chakra without exploding like madara, they scale to their chakra reserve, making them multi solar to solar lowballed
This statement is referencing the Otsutsuki clan from the Naruto series, who possess abilities that allow them to absorb the chakra (energy) of planets and stars to increase their own power. The mention of Madara refers to a character who attempted to absorb the energy of the Divine Tree, causing him to lose control and ultimately self-destruct.
If an Otsutsuki is able to successfully absorb this chakra without suffering the same fate as Madara, they would be able to significantly increase their power level. In terms of power scaling, they would be considered to have a chakra reserve that is potentially multi-solar level, at the very least on the level of a single solar system.
Overall, this statement implies that the Otsutsuki clan members have the potential to reach incredibly high levels of power by absorbing the energy of planets and stars, making them formidable opponents in battle.
