Lord Frieza has jumped into a warp portal that has landed him and his crew into another universe, very similar but vastly different than what they are used to. Frieza lands on Earth in an open valley and sends his coordinates to his back up reciever. In an hour many ships, pods and squads join the invasion. Frieza plans to wipe out the most powerful threats and take over.
His army consists of:
Frost
King Cold
Cooler
Salza, Doore, and Neiz
Lord Chilled
Sorbet, Shisami, and Tagoma
Abo and Kado
The Ginyu Force
Zarbon and Dodoria
500,000 Soldiers
Everyone is in their current form before death
How long would it take him to take over, or will the available heroes be able to stop this threat?
