Terriermon

Terriermon is a Beast Digimon whose name and design are derived from the Terrier dog breed. With one horn growing from its head, it is a Digimon wrapped in mystery. It can be classified as a Beast-species Digimon from its body structure, but it's still not understood how its form changes throughout its Digivolution. Also, it is rumored that it is sometimes born with a twin, Lopmon. Where Lopmon has three horns growing from its head, and has the personality of a lonely crybaby, Terriermon has only one horn growing from its head, and has a calm but robust personality. It's a very cute type of Digimon, and from its calm behavior it doesn't seem like a "Combat Species", but when it battles, it shows that it is more powerful than it appears.

Digimon Battle
Terriermon is a Vaccine Rookie Digimon who digivolves from Gummymon at level 11. The "Terriermon T.F.U." item turns the player's current partner into a Terriermon, maintaining its level but resetting its skill and stat points. It has a stat build of 3-1-3-1. Terriermon's Skill 1 is Blazing Fire, which is a distant single target skill, and its Skill 2 is Terrier Tornado, which is also a distant single target skill. Terriermon gains the ability to digivolve to Gargomon at level 21, Rapidmon at level 31, and MegaGargomon at level 41. It can also replace its Ultimate form with GoldenRapidmon and its Mega form with Raijinmon through Card Digivolution, and a special event Terriermon instead has BlackMegaGargomon as its Mega form.
