His logo which is a large brown "S" (meaning "hope" in Kryptonian) and some dark gold, the suit's cut on his body, a gold oval and silver embroidery which continues onto the legs.

Jor-El was a renowned scientist on Krypton married to Lara Lor-Van. He attempted to warn the Kryptonian council about Krypton's destruction due to its unstable core and wanted to send a Kryptonian genetics codex to other worlds to save their species, but the council refused. General Zod, his old friend, and his army then arrived and tried to overthrow the council, and Zod offered him a place in reshaping Krypton's government. Jor-El refused, escaped and stole the codex.
He returned home, and imprinted the codex on his newborn son, Kal-El, who was the first naturally born Kryptonian in centuries. They prepared to send him to Earth before Zod arrived, and when he did, Jor-El fended him off, long enough for Laura to launch Kal-El's ship. Zod then killed Jor-El in rage.
Clark Kent (Kal-El's Earth name) discovered an ancient Kryptonian scout ship, and inserted Jor-El's artificial intelligence into the ship's mainframe. Jor-El explained Krypton's history, Zod's intentions, and why he was sent to Earth. He also presented Clark with his uniform.
Zod took control of the scout ship and Jor-El attempted to talk him out his plan to turn Earth into a new Krypton. However, the sectarian forced the A.I. to disappear and seemingly destroyed it.
