Signiton appears as a stout version of Signibble, as his arms are more muscular and his build is more sturdy. He wears a yellow hakama.
Unlike Signibble, he can increase your reception no matter where you are. In the anime, he instead eats signals like Signibble and grows bigger when he eats more signals.
Freed from the Crank-a-kai:"I read your signal loud and clear!"
Freed from the Crank-a-kai (Wibble Wobble):"Buzz buzz! You must have sensed my signal in there. Let's be friends!"
In the anime
Signiton appeared in YW007, although instead of increasing reception, he was decreasing Nate's reception. Nate used Robonyan F's Onechanside form, which fused him and Nate together, creating Keita Type-F. This caused Nate's reception to increase greatly.
