History
The early history of the Kronan Warbot is largely unknown.

When the Kronans visited Earth, they encountered Thor and decided to capture him for study and research of him. But the Asgardian thunder god never yield and fought them all with his Mjolnir, his hammer.

With no choice, they had unleashed their Warbot against Thor and it nearly won until Beta Ray Bill arrived to help his comrade. Together,with their hammers powered together the two had defeated the Warbot and sent the Kronans fleeing back to space but Beta Ray Bill followed them to Sakaara where he and the others were captured for gladiatorial battles.
