Julio "Flinch" Escala is a Mexican- American kid with a diet consisting almost entirely of junk food. However, this causes him to be constantly hyper, twitching constantly and turning anything he tries to say into speedy gibberish. His catchphrase is "I AM MIGHTY!" He lives with his grandma Mama Rosa, who loves soap operas.
Flinch is very hyperactive, which is the weakness Benjamin upgraded. Benjamin gave him a harness that converts his hyperness into energy when you twist it, giving him super strength and super speed. He can lift up to 5 tons and run over 100 MPH. It will also calm his nerves, allowing him to talk English, not gibberish, and it can absorb energy.
