| A member of the Fatal Five.
Mano's homeworld is the pollution covered world of Angtu.
Natives of Angtu must wear special suits and helmets to protect
them from the atmosphere of the planet. Mano's mother was exposed
to Angtu's atmosphere while pregnant with Mano and as a result
Mano was born with a disc on his right hand that disintergrates
anything it touches. Mano destroyed his entire planet using his
disintergration touch.
Mano was rescued from having his arm amputated by Ferro Lad in
return for helping the Legion of Super-Heroes defeat a Sun-eater
that threatened Earth. Mano and four other villains were
brought together to form the Fatal Five and continued working
together after the crises was over.
Mano can only control his disintergration disc by wearing a special
glove. He also is forced to wear an enviromental suit to allow
him to breathe the atmosphere of his home planet. |
