Lean yet powerful muscle packed into places that were once baby fat, lustrous, thick fur the color of snow, razor-sharp extendable claws, teeth big enough to rip chunks out of flesh like a shark, and a massive size upgrade, those were the physical changes Glacia had experienced.

Overall, she had merely aged up, grown slightly, and had her features mature, or at least on a surface level, that is.
