Tyutyumon is a Beast Digimon. It is a tactician Digimon that has a tiny body but also a shrewd mind. As its plans are absolutely precise, they are enough to admirably guide even the slow-footed dullard Damemon and earn great military gains through combat. Only victory is important to Tyutyumon, and it considers the advancement of everything according to its plans to be more important than anything else. Its battles are settled before they even begin. It must be so, and it will even become partners with someone to do so, but will still betray them at any time. Lukewarm words like "friendship" and "trust" can't even be found in Tyutyumon's vocabulary. As for those who disturb its plans, it manipulates them at will with its "Tyutyu Twitter".
