All Four Riders will transform into Hunter Gamer LV5 to defeat Proto Graphite Bugster. Looks like it's going to be the end of Graphite.
Kamen Rider Ex-Aid Hunter Action Gamer Level 5 (Dragon Fang) can evolve into Kamen Rider Ex-Aid Hunter Action Gamer Level 5 (Full Dragon).
During the Transformation, the Gamer Driver shouts out "Doradora Dragon Knight Hunter Z! Do-Do-Drago Kni-Kni-Knight!"
By the way, your guess is right. They have forgotten about Level 4.
