Tornado Twin (Don Allen)

Don Allen, half of the Tornado Twins duo, is the son of Barry Allen (the Flash) and Iris West, and he became the father of Bart Allen (also known as Impulse, Kid Flash II, or Flash IV). He inherited super-speed abilities from his father and passed them on to his son Bart, continuing the lineage of speedsters in the Allen family.
==Personality== 
According to his mother, Iris, Don was an introverted child with interests in science and technology, much like his father in his childhood. He is sensible and rational.
Don is depicted as a good husband to Meloni and a good father to Bart. He uses his super speed to fight crime and willingly puts himself in danger to protect others. In a heroic act, he sacrificed himself, along with his sister, to the Dominators during the Invasion in order to save their friends and family.
==Biography==
Don Allen was conceived in the 30th century after his father's retirement but was born after Barry's death during the first crisis. Along with his twin sister Dawn, he inherited a fraction of Barry's speed. Since they never had the opportunity to know their father, they often experienced feelings of jealousy towards their cousin Wally West., who had a close relationship with Barry and served as a father figure to him.
Due to the policies of Earthgov, known for exploiting metahumans, and the prevalent xenophobia on Earth at the time, Iris encouraged her children to hide their powers. When Wally arrived in their century after being lost in time following a battle with Savitar, he was surprised to discover that they weren't using their speed to fight crime. However, they sprang into action to save Wally from a mob that he had unsuccessfully tried to stop from lynching an alien. The twins then shared some of their Speed Force energy with Wally to help him return to his own time. This encounter likely had an impact on the Allens, as they later began operating as the superhero duo known as the Tornado Twins.
Don eventually married Meloni Thawne, the daughter of the Earthgov president, whose family had been mortal enemies of the Allens for centuries. They had a son named Bart, who would later travel to the 21st century and become Impulse, and later Kid Flash.
After Bart's birth, their family was attacked by the villainous Professor Zoom, a Thawne who sought to end the union of the rival families. Don, Dawn, and their families attempted to escape to a parallel Earth using the Cosmic Treadmill. However, Zoom sabotaged the device, causing an explosion that created a rift in the multiverse. Zoom was ultimately defeated by an army of three different Legions of Super-Heroes, but Don and his family were left stranded on Earth-247.
Don and his sister sacrificed their lives to protect Earth from the Dominators. Not long before the Crisis on Infinite Earths, Barry Allen and Iris West traveled to the 30th century, where they settled. There, they conceived a pair of twins: Don and Dawn Allen. Unfortunately, Barry could only spend a month with his children before being called back to the present day to aid in the Crisis, where he was seemingly killed.
In the following years, Don and Dawn grew up and inherited their father's super-speed, becoming the Tornado Twins. Don later became the father of Bart Allen, who would eventually travel to the present day alongside his grandmother, Iris.
== Prime Earth==
Eventually, Don and Dawn were seemingly lost in battle against the Dominators but were saved by Eobard Thawne, Barry's greatest enemy. Thawne used his abilities to corrupt them with the Reverse Speed Force, turning them to his side. He unleashed the twins on a future version of Central City against an aged Flash and brought them back to the present to join his Legion of Zoom.
The Tornado Twins were later confronted by Impulse, Don's son Bart. Bart managed to convince them to stop fighting when they realized that Thawne had manipulated them using the Negative Speed Force. Don and Dawn began to fade, and in his final moments, Don expressed his pride in his son before disappearing.
Don and Dawn were later visited by their parents, who traveled to the 30th century using the Cosmic Treadmill from the Flash Museum. The Allen family had numerous adventures together before Barry and Iris tearfully.
== Powers and Abilities==
The Tornado Twins inherited one-third of their father Barry Allen's speed, as they are known for their connection to the Speed Force and their ability to fly and generate tornadoes, hence their nickname.
===Powers === 
*Speed Force Conduit: Speed Force conduits possess a connection to the Speed Force, a cosmic force that allows its users to surpass the limits that hold time and space together. As conduits of the Speed Force, all aspects of their physiology are accelerated and enhanced. 
**Accelerated Healing: By having a connection to the Speed Force, every Speed Force conduit has incredibly fast healing ability and can heal from most injuries in seconds and devastating injuries in minutes.
*Enhanced Senses: The Speed Force enhances the speedsters' senses, allowing them to perceive and process thoughts faster than a normal person. Phasing: Speed Force conduits can tap into the Speed Force to vibrate their molecules in a way that achieves short bursts of intangibility, allowing them to pass through objects.
*Speed Force Aura: The Speed Force manifests an aura around the speedsters and everything they carry, protecting them from the adverse effects of their speed, such as air friction.
*Superhuman Durability: The Speed Force Aura also protects speedsters from kinetic impacts, making them much more durable and resistant to injuries than an average human.
*Superhuman Stamina: The Speed Force grants its conduits a significant increase in stamina, allowing them to fight or run for much longer than an ordinary person. Although it's a substantial increase, it is not unlimited. Superhuman Speed: Being a Speed Force conduit grants the user imperceptible amounts of speed. All powers that conduits possess are derived from their speed. This also includes:
*Superhuman Agility: The speedsters' agility, balance, and bodily coordination are enhanced to superhuman levels. This allows them to maneuver easily while moving at superhuman speed. Superhuman Reflexes: In conjunction with their enhanced senses, the speedsters' reflexes are immensely heightened, allowing them to dodge or react faster than normal.
