Project Supernova
From Transformers Wiki
What little kid doesn't wish they could fly? Just that held true for Alexis, Carlos, and Rad when they were young, which is why they came up with Project Supernova. It was a plan to build a flying craft, for which they used various materials scavenged together, most prominently cardboard and balloons.
Another version was later built by the Mini-Cons Sparkplug, Grindor, High Wire, and Sureshock as a gift to their new friends. This one was also made of stuff lying around, but at least had a higher percentage of strong materials and an engine.
Fiction
Dreamwave Armada comic
Project Supernova was completed in utmost secrecy in the laboratory (garage) of the residence of Agent Secret Agent, formerly coded as Agent Awesome. Agent Sidekick functioned as the project's head engineer, while Agent Secret Agent and Agent Bubblegum concerned themselves with security when not assisting him.
On launch day, Agent Bubblegum and Agent Secret Agent had an argument over the password "Booger Burger", Russian spy activity and priorities, but all was quickly shoved aside when Project Supernova was declared free from malfunction and could be taken out for its maiden flight. The three brought their work, covered under a large piece of cloth, to a small cliffside. After a ceremonial speech by Agent Secret Agent, Project Supernova was shoved off the cliff, successfully remaining airborne.
At its height, the dream was popped by an attack of the unfriendly neighborhood bullies. Its source of lift gone, the craft crashed down and became irreparably broken. The harsh downfall made the three decide to abandon the project, and they would have, if not for one peculiar result of these events. When Rad tried to retrieve the bike helmet that he had given the test dummy, he accidentally reactivated a group of four alien robots. Not knowing what to do with them at first, he had them hidden in his garage, where Carlos gave them his toolbox (still containing Project Supernova's schematics) so they could try to fix themselves.
The next morning, the three humans returned to find their "guests" had not only patched themselves up, but also build them a new and improved version of Project Supernova. A much enjoyed test drive followed thereafter, until Megatron showed up. Armada #3 With Project Supernova and some clever driving, they escaped the giant and retreated to the garage for some time to think. When he came after them again, the humans wanted to use Project Supernova again to flee, but the Mini-Cons deemed their new alternate modes a better means to get away. Armada #4
