We all know this ain't really about Katsuyu, Femme.
It's another "Sakura and her jutsus/assets are godly" thread. Just because Katsuyu may be able to tank a Tailed Beast Bomb, doesn't mean jack s.hit for Sakura lol
She may tank one with Katsuyu's help, but by the time the smoke clears out, Naruto already shot 20 more. Or Sasuke got her with Amaterasu, or Obito/Kakashi Kamui sniped her head off, or Madara dropped meteors on her (or negged her with limbo and stabbed her again lmao) or Might Guy rekt her with Hirudora, or Lee speed blitzed her like he did to Madara, or Hinata neutralized her with gentle fist, etc etc.
Sakura isn't the goddess your fanfic and fantasies make her out to be. If she was, she would've been more relevant. She would've had a significant role in the 4th Ninja War as a fighter, not as back-up. She wouldn't have been so overshadowed by the rest of Team 7, she would've helped against Toneri, not fodder puppets.
But to answer your original question, yes, she may be able to tank a Tailed Beast Bomb. Two, unlikely. Three? Nah
She's not immortal, and it'd be completely, and utterly retarded to believe her physical "absorption" is limitless. Otherwise you're gonna be telling me she'd absorb a Kamehameha or a Death Ball from Frieza? Don't be an idiot. You make an underrated character like Sakura look worse than Kishimoto already did. It's time to stop, mang.
