"That's right... It's fine if you tell me... to fight... I'll keep answering with the same answer... MAZIN GO..."
Tetsuya is an orphan kid who was raised by Kenzo Kabuto to pilot the giant robot he was developing and repel the Mycenae invasion Kenzo and his father -Dr. Juzo Kabuto, creator of Mazinger Z- were frightened of.</span>
Tetsuya is prideful and efficent but deep down he is a person insecure and frightened of being alone. He had been a lonely kid until Kenzo took him in. He felt Professor Kabuto had given him a home and someone to call "father", and he would do anything for him.
He completely devoted his life to piloting Great Mazinger and combatting the Mycenae Empire. He trained and honed his skills to honor his father, and he refuses to quit or flee because in his mind it would mean letting his father down. Due to his time spent focused on piloting Great Mazinger his interpersonal skills were severely under developed, thus coming off as blunt or rude with most of his encounters.
When Koji Kabuto returned, Tetsuya became afraid and jealous, fearing everyone -including Kenzo- would forget about him, and he would lose his father and the only thing gave meaning to his existence: piloting Great Mazinger. So, he got aggressive, hostile and confrontational, and even he refused to help Kouji when he needed him.
He took the intiative to change his ways after his jealosy and fear and overcame them.
Although similar to Kouji in some aspects –such like being hotblooded and resilient, he was also pretty different. Where Kouji was carefree and enthusiastic, Tetsuya was serious, focused, gloomy and cranky(kinda like going from Jaden Yuki to Yusei Fudo when GX ended and 5D's started). He was completely focused on his duty whereas Kouji had a life beyond of piloting Mazinger Z. Maybe due to him being older, Tetsuya was slightly more mature than his predecessor. However, unlike Kouji, he didn’t outgrow his competitiveness.</span>
Super Robot Wars Alpha seriesEdit
Tetsuya went from normal not really important enough character in the first game, into one of the more developed and important character to the plot and backstory of Alpha Gaiden, and become Touma's main mentor(since he gaves him his training schedule to fit his role as Drill Sergeant Nasty) in Alpha 3
Tetsuya also stars in a story depicting the prequel of Alpha Gaiden, which serves as the moment before Egret Fehu does his job at the Earth Cradle. What does Tetsuya do ? Opening with the classic Thunder Break move to save the crippled base defense line of Gespenst and Valkyrie Squad, then, after making a boast that he doesn't care about anything, his job is to give a trashing to the enemy, he evenhandedly fights a whole Army of Mycenaean Dragoon Squad resulting in a cracked and crippled Great. Then Ryuuma Shogun come only to get handled by a Thunder Break and a point blank all or nothing stab with Mass produced Photonic Beam Saber with a little help from Venus A.
This feat is so awesome that SANGER ZONVOLThimself stares at his prowess in such an expression that signifies fear. You read it right. Sanger motherfucking Zonvolt himself FEARED Tetsuya Tsurugi.
- Violence Jack: In Violence Jack Hell's Wind is some dude named Tetsuya who's in love with (and probably b0ning) a chick named Jun. They gets caught by Hell's Wind and he gets FREEKIN CHAINSAWED DEAD!!(in the manga the gang only hassled them and they lost control of their car and crashd(jun fell out and didn't blow up))(also in dA MANGA the bikers killed him b4 the quake f'd japan). Jun went bada55 and went after em later. it didn't go well.
