Mr. Sunshine

Mr. Sunshine is the main antagonist of Pikuniku.

Pre-Game
Mr. Sunshine used to live in a small community in a mine which their main goal was to connect the entire island with the metro. However, they all dig too close to the volcano and they all perish except Mr. Sunshine. Mr. Sunshine moved in the volcano and built robots and mechs that work for him. Mr. Sunshine ran an ad about taking all the useless "junk" away from each village and in return giving money. However, Mr. Sunshine was actually taking the essentials materials of each village. He sets up multiple billboards in towns.

Early-Game
Mr. Sunshine takes Eli, one of the villagers in the valley to Sunshine HQ for a "tour", but instead being for an experiment to make a "sunshiner". He then drops lots of money onto the village.

Mid-Game
While off-screen, Mr. Sunshine took data from Eli and a pink leaf to create a "sunshiner". Mr. Sunshine then comes and steals Piku away himself and locks him in a jail cell in Sunshine HQ after beating his mechs the third time.

Late-Game
Mr. Sunshine is seen taking to the robots about what his great city is going to look like. He asks if the buildings are ready for the "great eruption" which will wipe out the entire island and its inhabitants except Mr. Sunshine. The robots already launched production, so Mr. Sunshine checks it out. Mr. Sunshine gets mad at the two lab robots for not having the "sunshiners" ready for the great eruption. He tells them to get it fully prepared by next month. Mr. Sunshine is seen getting ready for the great eruption, but Piku steps in. Mr. Sunshine tells Piku his plan: the lava is going to flood the island; the robots will put out the fires with the water from the lake; the robots will install building made from the wood from the forest; the robots will plant some corn from the valley. Mr. Sunshine calls in a mech to shoot lasers at him, but fails. He then gets in a fight about their wages and the robots controlling the mech stop attacking Piku. Mr. Sunshine then runs off and attempts to start the great eruption himself, but Piku follows him. Mr. Sunshine spits out corn from his paddle boat, attempting to get Piku, but misses. Mr. Sunshine then starts the great eruption with Piku and him on the hatch, but realises the lava was more powerful than he imagined. They both get launched into space, where Mr. Sunshine gets kicked off into space, never to be seen again.

Post-Game
Mr. Sunshine plans to build a "sunshine planet", but realises that it's going to take a very long time to get to a planet. All of Mr. Sunshine's robots and mechs get laid off and work other jobs.
