>>45010150I have a few ideas, one of my personal favorites is for a mid game dragon ( a littoe outdated now that Duraludon is a thing, but I'll share it anyway.)
Name/Type: Drakhelm (Dragon) --(Lvl 40)-->Drakarmor (Dragon/Steel)
Abilities: Bulletproof, Battle Armor, Speed Boost (not final)
Special Ability (obtained if Drakarmor evolves in an electrically charged area): Levitate
Stars: not going to post specific numbers, but they would focus on physical attack and speed, with average defenses.
Design: Drakelm (name comes fron Drake/Drakon, meaning a dragon without wings, and Helmet) is a small steel-blue lizard with metal forming a helmet on its head. The rest of its body is undefended at this stage, and the helmet is heavy, so Drakelm is slow and not very defensive.
Drakarmor (from Drake and Armor) is a large drake with longer front legs (pic related) in its standard form, drakarmor's front legs, head and back are heavily armored woth metal plates. In its float form, Drakarmor's armor is much more aerodynamic, and it lifts its legs to hover over the sand of its desert home.
