Eddie GrandSmith

Edwin GrandSmith is the grandson of Donovan GrandSmith, a wealthy resort chain CEO. Tending to be slightly arrogant, off-putting and selfish, Edwin was in the underwater resort when it was attacked by some robotic jellyfish/octopus-like aliens, that almost seemed like machines. After seeing Ben Tennyson disappear and "suprisingly helpful aliens" appear, he began to guess Ben's secret. After being trapped with Ben and his cousin Gwen in a tunnel that was rapidly filling with water, Edwin finally guessed Ben's identity and revealed this. Edwin then traveled with Ben into a chamber with the Undersea Manta Ray, saw Ben transform into Upgrade, and escaped via the upgraded sub. He keeps Ben's secret from his grandfather.
