"Galatea was stronger than supergirl "
Yamcha trained with North Kaio. Yancha was not as powerful as Piccolo, but I believe he has the skills to defeat Recoome or Burter (at the end of training).
Captain Marvel can defeat Ginyu. In suits of physical force the animated version of Cap Marvel surpasses 1.500.000 lbs.
Cap Marvel has a speed of Superman (Superman in the animated series (1996), Superman and Flash have almost the same level (But Flash is a bit faster). Captain Marvel has a resistance close to Superman (Superman against Doomsday within a volcano. In the animated movie Brolly 2 (I do not remember the name of the movie). Brolly had to use an energy shield to protect from the lava).
Flash in the animated series, also has the speedforce.
Yancha, Flash and Captain Marvel can win this duel without problems. (My opinion).
Galatea (Power Girl from Justice League Unlimited) can lift 1.500.000 lbs without problems.
