The Charge Axe/Blade in MH4 converts energy stored from hitting things into energy for a more solidified defense when the canister is charged into the shield. On top of this, the combined weapon unfolds into a gigantic battle axe that harnesses said energy for its skull bashing blows. The weapon transforms because it can serve different purposes functionally. Jaune's just...transforms and I guess he has somewhat more reach? The weapon still does the exact same thing as it did before.
