Chapter 143

Let's Duke It Out, Rappa-kun! is the one hundredth and forty third chapter of Kohei Horikoshi's My Hero Academia Manga.

Summary
Excited that the battle is going to get more interesting, Rappa asks Tengai to let down his barrier since he doesn't need it, but Tengai replies that Rappa should not be so selfish since they must not forget Overhaul's orders and that they must use their combination to ensure victory for Overhaul's sake. Annoyed, Rappa strikes Tengai with multiple fast punches, only for Tengai to raise a barrier to shield himself from Rappa's attacks. Tengai admonishes Rappa for his foolhardiness, to which Rappa replies that he was deciding things for him which he didn't like; Tengai ends the argument by saying that Rappa can do whatever he likes as long as he takes care of business. Satisfied with Tengai's understanding, Rappa agrees with him.

Now that their small argument is over, Rappa turns his attention to Fatgum and strikes him with fast multiple punches like before. While he withstands Rappa's attacks, Fatgum ponders about his next course of action; Rappa's attacks are too fast for him to dodge and by simply tanking Rappa's attacks he will eventually wear down. Even if he was able to fight against Rappa, Tengai will raise his barrier to protect him. Fatgum concludes that taking down Tengai is the best course of action for winning the battle, but this will prove difficult since Eijiro is badly hurt. Having no choice, Fatgum taunts Rappa into a fight to determine who is stronger; Rappa's punches or his own body.

Fatgum demands that they duke it out, making Rappa extremely excited. Tengai decides not to intefere, which makes Rappa happy. Rappa launches an assault on Fatgum with his multiple fast punches while Eijiro watches in disgrace as he is unable to do anything.
