During a garage sale Danny sells Dash Portals XL and gives him the upgrade disc for free to help his computer run faster. Unbeknown to Danny, due to his earlier confrontation with Technus all the technological supplies from the garage sale have been affected by ghost energy. So when Dash uploads the Portals XL software to his computer, he also unknowingly uploads Technus who uses the computer as the head of his technology-based battlesuit. However, due to the software having some glitches which become noticeable via malfunctions when Technus is about to battle Danny in Dash's room and Dash not having upgraded the software, Danny and Technus have a brief skirmish over the upgrade. This ultimately leads to Technus winning the battle, upgrading and becoming more powerful than Danny. Later, after Danny reunites with Sam and Tucker, Tucker manages to hack into the software thanks to Sam's wealth and the newest version of Portals XL, which fortunately has a giant hole in its security system. This allows them to power Technus' armor down.
The desktop icon for Portals XL can be seen on Danny's computer in "Identity Crisis."
