here's one I was inspired to create the following mech from Claymore's "Invincible" mech AND from looking at the Striker and thinking "I want a lowtech assault that can dish out the damage and never have to reload!"
So the story goes like this. The Free Rasalhague Republic... yada yada yada... to celebrate their newfound independence, decided to commission a home grown battlemech using their knowledge and available resources as of their birth as a nation in 3034. They had a large battlemech manufacturing base, and even some Lyran and Kuritan expertise to help them with the new design. Comstar frowned upon the endeavor at the time, but by this point so many other nations were doing it that they made no overt moves to stop it. The design had to reflect the national pride of the FRR citizens, while still being an effective machine.
The SW variant is...

The Clan Invasion variant goes like this. Remove 5 Heat Sinks and upgrade the remaining 16 to double strength. Remove Flamer. Upgrade PPC's to ERPPC's and Medium Lasers to Medium Pulse Lasers. It only adds around 1 million C-Bills I believe to the cost, so not a big jump in price there. Also well within the Republic's ability to create. Alas, it does not match other Clan Invasion upgrades in that no Streak SRM-2 was installed. I'm sorry.

The only other variants are the 87, which upgrades the myomer bundles to triple strength. Although most pilots will gladly tell you that it already hits pretty hard; and the 84, which is a field refit of the 85. It upgrades the armor to Ferro Fibrous, which maxes it out, and 2 of the Medium Lasers become Medium Pulse Lasers.
The primary planet manufacturing the Jotun was not lost during the Clan invasion, and therefore the Jotun has remained in service with the Kungsarme throughout its history.
