Zedicon's contributions on 1.5.0 were centered on sprites from Mega Man 8, since content from that game would be introduced in that update. He contributed partially or totally to the sprites of weapons, while he also designed backgrounds and tiles. 
His final task for 1.5.0 was to create a promotional picture for 1.5.0 where Mega Man, Proto Man and Bass were in front of Grenade Man, Astro Man, Cut Man, Plant Man, Concrete Man, and Tornado Man. It was integrated into the trailer and let as an image to use for gameplay showcases.
Due to medical reasons, he left during 1.6.0's development.
