Despite early tension between him and Saturn Girl, Garth's initial period with the Legion passed with little trouble, until his sister showed up. At this point, they were only permitted to have one Legionnaire per world and Garth, classed as a runaway, was not who Winath wanted to represent them. Ayla, codenamed Spark, was apologetic, but neither of them had much choice in the matter and after he nearly leveled Legion Plaza in his fight with Ultra Boy (after UB had threatened Ayla), he quit rather than embarrass Rokk or Imra any more by letting them plead to let him stay.
