Aarl, better known as Size Lad was originally a soldier on the planet Murra.

They lived in a militaristic society, which led to their mind set of conquering Earth and the rest of the United Planets. However the planets government learned to their dismay that the Legion of Super-Heroes had heard rumor of a pending invasion and discovered that the Legion intended to implement "Plan-R" to successfully defend against the invading forces.

Murra's military power sent three spies to infiltrate the Legion of Super-Heroes so as to steal the secrets of Plan-R. Aarl was selected along with two others, Xaxan and Graah to take an experimental pill which gave them special powers. The three newly powered spies travelled to Earth and posed as Legion applicants. The Legionnaires were so impressed with all of them that they were all inducted as members. Aarl and his team found the plans for "Plan-R" and headed back to Murra.

What they did not know was that the Legion was on to them the whole time. The induction of the three spies was a ruse which allowed the Legion, and thus the United Planets, to locate and neutralize the planned invasion.


  • This version of Size Lad is no longer considered part of canon continuity. All history and corresponding appearances of Size Lad were erased from continuity following the events of the limited series Zero Hour: Crisis in Time (1994). They were brought back into the main continuity in The Lightning Saga (2007), up until DC Rebirth (2016). Even though versions of the character may have since appeared, this information does not apply to those versions.
