An Armor-level Dinosaur Digimon which evolved through the power of the "Digimental of Courage". It is fierce especially amongst Dinosaur Digimon, and is in a hostile relationship with Tyranomon, who is the same type. It possesses powerful leg strength, and Allomon's feature is being able to advance at blistering speeds through posing level by tilting its head before that. Its Special Move is spewing a super-heated air (Dino Burst).

Its leg strength has developed further, and though it's a large Digimon, it carries a keen-witted nature common in small Digimon. Its running speed has also increased, but this large Allomon soars and it is said that there are many Digimon which have seen the sight of it capturing its enemies by springing onto them. Having learned a new Special Move called "Dino Flash", superheated air it fires from its mouth in an instant like a flash, it has adapted its own keen-witted self as a consequence.

勇気のデジメンタル”のパワーによって進化したアーマー体の恐竜型デジモン。恐竜型デジモンの中でもとりわけ凶暴で、同じ恐竜型のティラノモンとは敵対関係にある。強靭な脚力を持っており、頭部を前に倒して水平の姿勢をとることで、猛スピードで走り抜けることができるのもアロモンの特徴である。必殺技は、超高熱の熱風を吐き出す『ディノバースト』。

脚力がさらに発達し、大型のデジモンではあるが、小型デジモン並の俊敏性を身に付けている。走るスピードも増したが、この大型のアロモンが飛翔し、飛び掛って敵を捕らえる姿を見たデジモンも多いと言われている。閃光の如く瞬間的に口から放つ超高熱の熱風『ディノフラッシュ』という新たな必殺技を身に付けたのは、自らの俊敏な体に適応した結果である。
