He is an Asgardian-shapeshifter hybrid.His mother was a shape-shifter and his father is Thor,however his mother became Loki's wife,and the latter threw 'Zaair'(His birth name)into a portal,but a Saiyan that was on Earth found the baby and raised him,dubbing him Spark.Spark can use lightning without the use of Mjolnir, though it's so dangerous that his lightning,if uncontrolled,could actually make Thor be hurt by it.Spark also knows every move of the Z-Fighters,often mixing them with electricity.After he grew up,he began wearing a mix of Saiyan and Asgardian armor and now wields Mjolnir,making his lightning more dangerous than ever.He can shoot electric beams out his eyes like heat vision and also out his hands,though he prefers not to,saying "it puts his Ki that goes there for a Kamehameha on the fritz until a minute has passed".He does not use Mjolnir to fly,rather,he flies like a Z-Fighter.He has a blue scarf that used to be a blanket before falling through that portal burnt it up,only leaving a scarf of it untouched.He stopped wearing it after his mother's death though.
