The story arc for Ayla Ranzz is completely original to this show, drawing no inspiration from the comics stories. In the comics she originally shared Garth's and Mekt's lightning powers, operating as Lightning Lass, before undergoing changes which gave her the ability to negate the force of gravity upon objects, inspiring her to take the name Light Lass.
The origin of Lightning Lad/Garth Ranzz' scar, and Mekt Ranzz' white hair are both explained, in flashback, as being collateral results of their initial encounter with the lightning beasts when their ship crashed on Korbal.
Garth Ranzz/Lightning Lad ends up with a cybernetic arm, just as he did in a classic comics arc from the 1960's.
