"Showdown with Raditz" (ラディッツとの対決, Radittsu to no Taiketsu; Viz "An Unexpected Strength") is the one hundred ninety-ninth chapter of the Dragon Ball manga, and the fifth chapter of Part II of the manga.
Rapidly approaching Raditz's location, Gokū and Piccolo continue to fly. Unable to handle the half-Saiyan's constant crying, Raditz locks Gohan into his Attack Ball, and, following Saiyan instinct, resolves to find a meal next. His scouter, however, tips him off to a large fighting strength; Gohan's fighting strength, in fact, and it is coming from the Attack Ball. Raditz, however, decides the reading is a malfunction and ignores it.
Gokū and Piccolo approach fast, and Gokū decides they should descend; Piccolo tells him this is pointless, as the device on Raditz's ear allows him to detect ki. The element of surprise is lost. Raditz once again detects a ki signature; two of them, one of them matching Kakarotto's exactly. Much to his disbelief, it is his younger brother — this also confirms the 710 reading he got from Gohan earlier was in fact true.
Landing in front of Raditz, Gokū proclaims he's here to get back his son, a statement that disappoints his older brother as a Saiyan. Piccolo impatiently removes his weighted training gear, and Gokū follows suit; Raditz notes that the removal of the gear caused their fighting strengths to increase. Amused by their efforts, but annoyed with his younger brother, Raditz decides he will instead kill Kakarotto, as he disgraces the Saiyan race. Effortlessly, Raditz charges at them, only to attack them from the back and take them by surprise, stunning both with his speed. However, Raditz drops another bombshell onto the two fighters: the other two Saiyans alive are even stronger than he is.
