A member of the Heroes of Lallor
Sev Tcheru is the real name of Evolvo Lad. Sev was born to
parents exposed to the radiation from an atomic accident that
destroyed the continent of Antillar on their home planet of
Lallor. Sev was born with the ability to evolve into a future
being or devolve into a primative ancestor. Calling himself
Evolvo Lad, Sev and four other youth with extra-ordinary powers
became the Heroes of Lallor. Sev and the other Heroes of Lallor
used their powers to protect their home and occassionally, the
galaxy. The Heroes of Lallor came to the aid of the Legion of
Super-Heroes on a number of occassions.
One can imagine that Evolvo was an extremely unpopular hero among
citizens of Lallor.
