Haruka can raise her hand in the air and use the crystal to transform into Super Sailor Uranus.
In Act 49 of the Dream arc, Haruka raised her hand and yelled “Uranus Crystal Power!” to give power to Eternal Sailor Moon’s Eternal Tiare and transformed into a form similar to Eternal Sailor Moon’s (referred to by fans as Eternal Sailor Uranus), along with the other Sailor Senshi.
In the Stars Arc, Sailor Uranus was “Eternal”. However Haruka was never shown shouting a transformation phrase for her Eternal form, but it can be presumed that the phrase is “Uranus Crystal Power, Make Up” like the Inner Sailor Senshi.
- A similar transformation brought about by Hotaru's power happened in the 1st episode of the 5th season of the anime.
