Gutsman is one of the Navis from the original games that still resembles his old design. Gutsman is Dekao's Net Navi, and has extraordinary strength. He can obliterate panels when he pounds the ground and can hit extremely hard. However Gutsman falls into the stereotype that the bigger you are, the dumber you are. Often, the only word we hear Gutsman say is "Guts!" though he does talk more from time to time.

Ever seen a huge giant robot (or program, I guess) blush? Gutsman has a huge crush on Roll, just as Dekao has a crush on Meiru. Gutsman is often trying to compete for her affections, though it seems plain that she is not interested.
