Weeks ago you stranded on a weird planet were they made a gladiator of you. The people there found you skills amazing. You had fight many fights and today it was time to fight against a unknown warrior.
"YES!" Thor boomed when he saw you walking in the arena.
Mad at Thor for not finding you earlier you didn't give in you sprinted towards him and so the fight begun. Eventually you won, the whole stadium cheered for you making your victory round.
If you have seen Thor Ragnarok. The song you hear in the end fight is:
Immigrant song by Led Zeppelin
