Danny's stamina
Superhuman (Likely comparable to Jazz, who despite having yet to train spent the majority of the day constantly
fighting off ghosts sent by Vlad Plasmius and showed no signs of fatigue.
[11] Danny himself is capable of using his powers multiple times in combat without getting tired quickly,
and has spent nights rounding up ghosts[14])
Ruby's stamina
Superhuman (Ruby can mutilate hordes of monsters by herself and can train for days with minimal rest and can fight through her long, arduous fights with the likes of Vegeta and Majin Buu, continuing to fight against Vegeta even after her aura broke. Endured the water of the gods for 6 hours straight, a poison described as causing unbearable pain to the consumer and even death and being stated to require immense will power to survive. When she was younger, she can fight hordes of Grimm for a day straight before tiring and she and her team fought on and off for three days straight with minimal rest
[103], with Ruby herself staying awake in the ever after for a extra day
[104] and could endure getting beat down by Neo's clones without a Aura
[105], as well as being comparable to the likes of Clover, Winter, Yang, Weiss, Blake, and Adam, who can continue fighting even after their Aura reserve has been drained. In the
Tournament of Power Ruby was able to fight through nearly the entire duration of the tournament despite repeatedly breaking through her limits and nearly dying multiple times, ultimately pushing herself to fight and eliminate Jiren alongside Vegeta even though she could barely move moments before. Got hit by multiple Pressure Points Strikes from Granolah and got up each time and continued to fight. Can engage in combat in low oxygen environments. Ultra Instinct Only lasts a few moments before regressing back to her base form. Although in the Moro arc, she can use Ultra Instinct -Sign- at will and it lasts longer and After training a lot, the form lasted far longer against Granolah as Ruby only dropped out of the form because of a vital strike when she was off guard)
