He’s 16 months younger than his sister, and his passion is science, as his Dad has spurred him to ‘be a thinker’ and imagine the unimaginable. Ethan’s world doesn’t have time for the mundane, like soccer, TV and hanging out at the Mall. That’s because he’s on a mission to become a great scientist like his dad. In between T-4 Missions and school, he’s consumed with the voracious reading of his Dad’s research papers and science journals, and conducting experiments in Dr. G.’s basement lab. He’s a ‘fish out of water’ when it comes to dealing with bad guys because he’s never even been in a fight! But it’s an opportunity to use some of his cool inventions.  
Ethan’s dress code never changes; jeans, shirt hangin’ out, Nike’s Air Pegasus Zoom 33 runners and a yellow cap - and he never wears socks! He and Madison have to be very careful to keep their 4MIDABLES work a secret from the world, and especially their folks. It’s easy to forget they’re still just regular kids with school work and curfews. Sometimes the stress of balancing their dual lives becomes a little too much for them to handle, which their parents attribute to them being teenagers!
