Allan describes himself as "the school's prize sad-sack! Even worse than Clark Kent!" He is a weakling as a result of a "rare disease" he contracted while visiting Hong Kong with his scientist and world-traveler uncle, Jake Vale.
Allan Vale is also an inventor of genius and an idolizer of Superboy, owning perhaps "the greatest Superboy souvenir collection in Smallville!" (SB No. 132, Sep 1966: "The Youth Who was Braver than Superboy!").
