Penny:

Weapon:

I drew this.

The wings are used for flight mode and nonflight mode.

Like this picture:

Penny's wings would extend to those on her back.

The weapons are different, the first one regular mode is a bit heavier than the guardian mode sword.

The regular mode in the laser mode would only cause the guns to go to cool down in twenty seconds while the guardian mode guns would coll down to ten seconds.

The Guardian swords would also be a lot lighter meaning more speed and attack range for slicing.
