Powers: Super strength and endurance, control of lightning.
Bio: Daughter of Thor in the MC2 Universe, Thena was attacked in error by heroes Nova and Earth Sentry as soon as she landed on Earth. In a fit of rage she battled the A-Next team to a standstill until stunned by a power-blast from Katherine Power.
Thena joined the team on their mission to rescue Kevin Masterson, not realizing that it was a trap created by Selene; as a way to use the Avengers' (and other heroes) powers to transform Earth into a newer version of Asgard. And even though both Thena and J2 were used as sacrifices for the spell; they manage to free themselves and Thena (under her father's orders) restores Kevin's powers, allowing him to become Thunderstrike.
