"Pokémon Diamond Version (Japanese:
ポケットモンスターダイヤモンド Pocket Monsters Diamond) and
Pokémon Pearl Version (Japanese:
ポケットモンスターパール Pocket Monsters Pearl) are
Nintendo DS games that are the first
core series Pokémon games of
Generation IV. The games were released in Japan on September 28, 2006, in North America on April 22, 2007, in Australia on June 21, 2007, and in Europe on July 27, 2007. They take place in the
Sinnoh region."
"Cyrus is the first leader of a villainous team to have his age confirmed (27).
Looker confirms his age in the Team Galactic Headquarters in
Veilstone City."
"Much like Generation III remade the Generation I games, the Generation II games also received much anticipated remakes in the form of
HeartGold and SoulSilver, and through details revealed in the five main games, Generation IV is thus known to be contemporaneous with Generation II, occurring three years after Generation I and Generation III."
Cyrus is canonically turning 50 next month.
