Within the Super Dragon Ball Heroes narrative, Yamcha competes in the Super Space-Time Tournament. During this event, he rescues Vidro from an attack by Hit, causing her to develop romantic feelings and express a desire to marry him. This potential romance abruptly ends when Vidro is revealed as underage, underscoring Yamcha's recurring romantic misfortune. In the manga adaptation of the Supreme Kai of Time Saga, Yamcha deliberately avoids confronting Mecha Frieza, recognizing his inability to defeat the tyrant. He survives an accidental kick from Super Saiyan Blue Goku—meant for Xeno Goku—by momentarily locating one of the Time Fairies. Later, Yamcha and Vidro join forces against Transcended Chilled, combining their abilities to execute the "Glass Homing" technique and overpower the foe. The anime portrayal shows Yamcha and Vidro maintaining effective combat against Chilled until reinforcements, Xeno Gohan and Android 16, arrive to aid them. These events occur in a non-canonical context, as Super Dragon Ball Heroes is a promotional series integrating diverse franchise elements without adhering to primary continuity. The storyline provides no further elaboration on Yamcha's background, character development, or motivations beyond these specific events and interactions.
