The name Silverbolt is a popular one in Transformers, working its way through numerous iterations of the brand. Go-Bots had a turn with Silverbolt, with a large flying wing plane that turns into a chunky robot, who is a redeco and retooling of Playskool's earlier Aerobot. Silverbolt would be released several times in the Go-Bots line but was renamed Silver-Bot.
The combined form of the Universe Micromaster Aerialbots is Superion, an amalgamation of six robots plus their pack-in accessories that serve as connectors, head, and extremities of the gestalt warrior. While in Japan, the original source of the design ( Sixwing , 1992) was available in a collected set, this combiner needed to be purchased one bot at a time in the 2007 Universe release.
