Mecha and Mercenaries
He hits things with swords and has a ridiculous "name".
Thunders has had a long and varied career, assuming “varied” means “hits things with swords”. Fortunately he is good at it. He has spent the last 18 months, give or take a few weeks, working with the Fortuna Group after skipping out on his previous shady acquaintances shortly before they were wiped out by rivals.
He claims to be older than he looks due to having recived at least one rejuvenation treatment, but he won’t say where or when, and he apparently started using the “Truck Thunders” identity about five years ago, leaving no record of where he was before then.
