In retaliation from Return iX combining with X and Zero to form the iX Armors, Enemice HL revives the fallen Hyper Limited Mavericks and combines them to make Mix Fort. Mix Fort then proceedes to attack X and Zero, but is destroyed without effort thanks to their armor.
The Japanese writing for Mix Forte is not the same that spells out Forte's. Forte's is spelt as フォルテ while Mix Fort's is spelt as フォート, making it closer to "fort".r. This pronunciation was used for the Mega Man X Legacy Collection's scans for the cards, rendering the name as Mix Fort.
