He first appears at the beginning of the episode with Kid Dynamo and tried to interrogate Bones, only for Kid Dynamo to stop him as he had met them before. Lightning explained that the dust from a meteor is what gives them their powers as Kid Dynamo invited them over to his house.
As Donkey Kong Jr., Bones, Ricky, and Lightning talked about how to stop Dr. Demise (Lightning explains that even his superior sense of smell could not pick up any trace of Dr. Demise's hideout), Ricky's father asks him to rake the leaves; after he does so, Lightning was momentarily distracted with a bone he found, allowing Dr. Demise to kidnap him prompting Kid Dynamo to rescue him; this was actually a trap set up by Dr. Demise in order to chemically eradicate his superhuman powers. After he was freed, Lightning gave a now powerless Kid Dynamo some additional meteor dust to replenish his powers.
He then accompanied Kid Dynamo in going after Dr. Demise at Sweetville Station, helping lure him into a pine tree to cover his helicopter in pine needles. Kid Dynamo then destroyed the helicopter and caught Dr. Demise, ending his schemes once and for all.
Back at his house, he had dinner with Donkey Kong Jr. and Bones before they would take off again in search of Donkey Kong. When Ricky's mother told him to eat vegetables to grow strong, Lightning hinted that he is already strong enough because he is the true identity of Kid Dynamo.
