Viktor Bolt was squire to Joker, one of Czar Wilhelm of Ruth's five elite warriors, the Shuffle Bogatyrs. Following the czar's overthrow by Voivode Julian, the young Gundam accompanied Czarina Aleena into her exile in the land of Lacroa, often serving as a bodyguard to her and her infant triplets. Now he takes part in a join Sol-Lacroan campaign across Sadrac to find the Sol Emeralds, seven magic objects which are believed to be key in defeating Julian and restoring Aleena to power.

Bolt is based on the GF13-013NR Bolt Gundam, from Mobile Fighter G Gundam (1994). You can see the original design here: https://www.mahq.net/mecha/gundam/g/gf13-013nr.htm
