My Isle of Armour team nicknames:
1) Gigantamax Inteleon - "Simo" - named after Simo Häyhä, a Finnish sniper who killed more than 500 Soviet soldiers during the Soviet Union's failed invasion of Finland in World War II.
2) Gigantamax Venusaur - "Rafael" - the name I always give Bulbasaur/Ivysaur/Venusaur, a play on "Rafflesia", the flower that Venusaur's flower is based on.
3) Galvantula - "Charlotte" - after the spider from Charlotte's Web.
4) Talonflame - "Kes" - after a British movie from the 60's about a boy who trains and befriends a kestrel, with a notoriously sad ending (it's basically Old Yeller but with a bird instead of a dog).
5) Hatterene - "Isobel" - after Isobel Gowdie, a real-life witch who lived in Scotland in the 17th Century and gave one of the most detailed accounts of witchcraft and its practices documented at the time. This name also fits with Hatterene's Fairy typing, because one of Gowdie's most notable claims was that she met the Queen of Fairies.
6) Mudsdale - "Magnus" - a reference to Equus Magnus, the horses from ARK: Survival Evolved.
7) Single Strike Style Urshifu - "Wojtek" - after a bear who was adopted by Polish II Corps during World War II, and was eventually given the actual rank of corporal in the Polish Military.
