Mego, with the purple suit, skin, hair, and glow power which gives him the ability to shrink at will. Contrary to some opinions, Mego is never seen enlarging except back to his normal size. Considering Hego's statement about his power in Go Team Go as: "He's a shrinker", Mego returning to normal size is most likely his "turning off" his power, and not activating a reverse of it. Mego is the second oldest sibling, after Hego. His power combined with his coloration makes him evidently based on the Legion of Super-Heroes member Shrinking Violet (yet another DC Comics comparison). However, his name and shrinking ability are more likely a reference to the Mego toy line, considering the identical pronunciation and his ability to shrink to roughly the size of an action figure. He possesses a large and easily wounded ego, and is rather defensive of his seemingly-useless power. After the team reunites, he expresses a desire to be the leader. Because of his self-absorbed nature, he seems to have an attitude very similar to Shego's. However, Shego still gets annoyed with his inability to see past his own nose. Mego doesn't really have a strong belief for justice, but he does show he believes, at least in part, that there should be some. Also, considering how Mego is self-centered and his power is the ability to shrink, he personifies the saying: "A man all wrapped up in himself makes for a very small bag". Through this, his name appears to be a mixture of two meanings. The Me for his narcissism and ego for his inflated ego.
