Armarouge is the evolution of Charcadet if playing Pokemon Scarlet, has a pretty good design, but a terrible shiny. I think only thing that changes in its shiny is its eyebrows turning blue basically. However, when it comes to battling, Armarouge can do alright since it has decent enough stats, and a pretty nice movepool. Only downside to Armarouge with battles would maybe be its abilities in Flash Fire & Weak Armor, but they can still be useful on occassions. Overall, I definitely still love Armarouge, but I've always been a bigger fan of the other Charcadet evolution still remaining, and I just don't think Armarouge has anything great that makes it stand out amongst the crowd when it comes to the pokemon left on my ranking.
