Umbriel

It would be interesting if she fused all her cores and various forms of energy. Honkai energy, for example, could be a nexus for a large part of her powers.

Nobody fights in space in Dragon Ball the closest thing to a fight in space was Goku vs Beerus and it was in the planet's atmosphere. Furthermore, Senjutsu is not another form of energy, it is a technique. Ps: Regarding the destruction of planets, this has never been a determining factor for victories in Dragon Ball. Senjutsu would be much more of a Hax than raw power like the Spirit Control technique that Vegeta learned in Yardrat to fight Moro since all his power to destroy planets was useless in the situation.

It depends a lot on the media, for example in Naruto senjutsu grants sensory abilities such as perceiving negative intentions, something that would be useful for Bulma to train her empathic abilities in Highschool DxD senjutsu grants healing abilities, attacking the opponent's organs, training and strengthening her own organs and even damage the enemy's soul and in Hells Paradise grants pseudo-immortality and insane healing abilities like a plant.

Since Bulma has such a strong connection with nature, how about she develop her own style of Senjutsu?

I didn't even remember that.

Which anime is this Gif from?

Honestly Kohina is the worst thing that happened in this fanfic.

I hope with this reward from the system she finally realizes how much danger she is in and finally invests in safety.

If Gwen goes to a DC universe again choose Justice League Unlimited and if it's in Marvel choose The Avengers: Earth's Mightiest Heroes 👍.

Yes but on the cover she has blue hair.
