Future Trunks (LOTSG)

Trunks, sometimes referred to as Future Trunks so to differentiate from his counterpart from the Prime Timeline, is a Saiyan-Human Hybrid and the son of Future Vegeta and Future Bulma.

Power
From a young age Trunks trained with Future Gohan in an attempt to gain enough power to defeat Android 17 & 18.

For many years Trunks was unable to match Future Gohan in his base form and was easily beaten when fighting the Androids.

Even after gaining the Super Saiyan transformation Trunks was unable to defeat the Androids.

Shortly before he went back in time Trunks was noted by Bulma to have become just as strong as Future Gohan, who was stronger than either Android individually when a Super Saiyan.

Future Trunks first showed his power in the primary timeline by instantly overwhelming Mecha-Freeza and King Cold, slaughtering them with ease as a Super Saiyan.

Despite his power Future Trunks proved unable to damage the prime timeline versions of Android 17, who knocked him out with one punch to the gut.

After training in the hyperbolic time chamber, Trunk's power increased immensely and was stated to be on par with Vegeta, who could dominate Semi-Perfect Cell as a Grade-Two Super Saiyan.

Trunks, when fighting Perfect Cell, entered Grade-Three Super Saiyan, and seemed to be stronger than the Android until it was revealed that Cell was not only toying with him but was also far faster and could effortlessly dodge his attacks.

Future Trunks later entered the Time Chamber a second time to master the initial Super Saiyan form like Goku and Gohan had, however despite being stronger than before he still proved unable to keep up with a Cell Jr.

After returning to the past Trunks was able to effortlessly destroy his time's Cell, Android 18, and Android 17.

Years later, after training with the Eastern Supreme Kai and achieving the Super Saiyan 2 form, Trunks was able to defeat Dabura and Babidi before Buu was released, however, he was unable to do so without the Eastern Supreme Kai and Kibito dying in the process.

Future Trunks later found himself near powerless against base Goku Black even when using Super Saiyan 2, being forced to retreat from every encounter with him.

After coming to the past Future Trunks proved roughly equal to Freeza's Final Form power after his revival and training.

Transformations
Super Saiyan - Trunks attained this transformation shortly after finding Future Gohan's body. This form boosts his power 50 times.
 * Super Saiyan Grade Two - During his training in the Hyperbolic Time Chamber Trunks gained this form, which boosts his power by a factor of 65 at the cost of increased energy expenditure.
 * Super Saiyan Grade Three - Trunks secretly attained this form during his training in the Time Chamber, and used to it fight against Perfect Cell. This form increases his power by a factor of 70, however, it slows him down and tires him out rapidly.
 * Mastered Super Saiyan - After his second trip into the Time Chamber Trunks mastered the initial Super Saiyan state, allowing him to fight far longer and with next to zero energy being spent on maintaining the form.

Super Saiyan 2 - At some point after defeated Cell and the Androids of his time, Trunks gained this form, which boosts his power by a factor of 100.
